Ford A/C :: 2001 F350 - Clutch Cycling On And Off / No Cold Air
Jun 25, 2015
I Just replaced the ac condenser filled it with new freon and now the clutch cycles on and off every few seconds but doesn't blow cold air. Does it need to settle for a while or run on high max AC for a while before it works properly? I filled it to the proper level. I'm pretty confident its full. Do I need to adjust anything? It hasn't worked in a few years I bet. I just got the truck. 2001 Ford F-350 7.3 diesel ....

At the first of summer I had typical A/C Clutch cycling not much cold air. Checked the Low Press side said it was low PSI took a Gamble that the pump was good and just filled it worked great. Lost All A/C the other day checked it out thought it may have small leak somewhere but clutch didn't cycle hardly at all Had a gut feeling it wasn't simple leak.
Well I just found a Hole in the condenser at the bottom Tube that runs across. So looking for new condenser. I also don't know what to do with recharging it and the ac oil in the system how much? maybe its safe to say most the oil was pumped out. Would standard procedure be to repair it then FLush cooling system to get to a baseline and then refill prescribed amount of oil and Freon

I have a 2001 ford f350 v10 dually. about 2 months ago it blew a plug out and i had it fixed and shortly after it developed a starting issue. It starts fine for a day or so then after it sits for a day it wont start without out cycling the key 5 to 10 times....It cranks fine just wont try to start or even sputter....took to a shop that replaced my jem Module and he had it for a week and only one time did it not start. I drive it home and it sits overnight and wont start the next day. took it back and he couldn't find out what is going on.
Its has started and ran just fine no issues once its running but shut it off for a couple hours you got a chance it wont start. I've eventually got it to start every time so far. The shop said my fuel pressure was 40 psi but would go down after it sat to about 10 to 20. The one time it did not start for the shop they said it had no fuel pressure but then he just cycled the ignition a few time and it started. What to check that would be normal like the fuel pump or relays and fuses. I should say early this year around jan feb it had the starting issue once and thought it was due to a autostart that was installed before I bought it and so got it going and just removed autostart when started having trouble with starting.

I have a 2002 F250 on which the AC compressor clutch is not cycling: I have checked and added coolant so low pressure is correct (don't have high pressure gauge). I checked the clutch air gap and it is at 0.030 " as specified in another post. I replaced the low pressure AC cycling switch (on the evaporator/dryer). With the AC on, I disconnected the AC cutoff switch and the clutch disengages. This circuit has the correct (>10V) going to it. I am thinking it could have something to do with the AC relay.
When you switch the ATC to a setting other than AC or Max AC, the clutch disengages fine. I noticed this problem because the AC shuts off when it is really hot, after I have been driving for a long while, about 1 hour or more. If you shut off AC, wait a few minutes, then turn on it works fine.

He has a 96 explorer and his ac compressor clutch was cycling on and off. So he went and bought 2 20 ounce cans of 134a and proceeded to add it to the evaporator service port. Of course a lot of it sprayed out side of it as it did not fit well (duh). So he has no Idea how much he actually got in there out of the 30 or so ounces he dispensed. He is laughing at himself with me on this. He says hi ahead of time
I have access to good gauges and a reclaimer and vacuum as I work sometimes for a residential ac guru. So what to do? I was thinking the evaporator should be changed out but I want a second opinion. Then vacuum and add new 134.

How would I test (if Possible) the A/C Clutch Cycling Pressure Switch on my 88 E-150 4.9L? I had to replace the evaporator, it was leaking along a seam. I have a feeling the Cycling Switch is bad too.
I was hoping for a simple test w/o Gauges. The Switch is in a real tough spot to remove it. I also heard they could be adjusted. There are no leaks in the system and no blockages, that we detected when we evacuated and recharged the system.

I purchased an 89 F350 460 EFI factory air. The air worked fine for the first 6 hour on the drive home then It just stopped blowing cold. When I got home I saw the air gap on the clutch was quite wide so I took the washers out, still was too wide. I could only get the clutch to pull in if I tapped it in by hand and it only stayed in for a short time. This was all last fall.
Today I replaced the clutch, compressor and drier, took it in and had it charged. They replaced the pressure switch because the compressor cycle on and off. Even after replacing the switch it still cycles on and off and I still have no air! They removed some of the charge but still no air. The clutch pulls in and runs for 2 sec every 15- 20 seconds. I assume the reason it cycles is a high pressure. What should I be looking at now?????

So my Ac is not blowing cold at all. I can hear the compressor cycling. I filled the sys with freon. Still not cold I am pretty sure I have a leak but wouldn't it still blow cold? What do I need to check to fix this? The temps are getting in the upper 90's and 100 s I need Ac bad...

I thought originally I had a leak so I tested with dual gauges I'm getting 85 psi on low and high side, which I believe is good. So I tried grounding the low sensor, then high sensor, then both, then both just pulled out and any combo possible. Still not engaging. Switched out the relay, checked fuses, still not engaging. Tried taking shim out of compressor still nothing. Jumped the relay and it will engage and air comes out cold. What should I check next?

2001 F350 7.3L with 140K. Have had it for 7 years and this has never happened. I let the engine warm up (I'm in Cheyoming and it gets cold!). I'll have warm air coming out at all settings (foot, dash, combo, etc) for a few minutes, then the air turns cold!
I've checked the actuator and blend door and they seem to be working properly. The heater hoses going into the firewall are not particularly hot/warm. Is there a valve or thermostat that could be shutting water off to the heater core? Cause that's what it seems is happening. Like starting off in the shower with warm water . . . then someone gradually turns it to cold. Then next time I get in, warm air to cold again!

I have a manually operated air conditioner. On cool days it seems to be working, but on hot days, after sitting for a while it can take 15-20 minutes for my air to come on after starting the car. It then stays cool for about 10 minutes and slowly transitions to warmer air and sometimes back to cool. I've had the freon checked and topped off, but that has not solved the issue.

I have a 01 f350 7.3 turbo dsl. will not start cold. engine turns over fine. plug into block heater over nite , will start! outside temp does not make difference. I have replaced glow plugs, glow plug relay, wiring harness under valve covers. Where to go from here?

I have a 2001 Nissan Altima. I seem to be having a fan problem. I started noticing that about 2 seconds after I turned the car off, the fans would come back on and run for ~25-30 seconds. I brought it in and my mechanic was thinking maybe a defective thermostat, so we replaced that. It still keeps happening, but now I've realized that the fans come back on anytime the car is turned off when the fans are running. If the fans are not running, they won't come back on. I've been trying to pay more attention to what is going on and when I first turn on the car, no fans are on (at least not the high fan, not sure if there are more than 1) After driving around town, the fans will turn on.
Normally, I believe the fan should then turn off once the coolant temp gets below a certain level. I let the car sit idling in the driveway for 15 min and the fans never turned off. I took it back to mechanic and repeated the idling for 15 min, fans never turned off. He checked the coolant temp with some sort of sensor and the temps were reading between 166-170 depending on where he aimed his device, so he said the fans should be turning off and it doesn't seem like the car is overheating.If he unplugged the temperature sensor, the gauge would go all the way to cold, but nothing changed for the fans, so he didn't think that was the problem.He took the fan relays along the edge of the car and swapped them around and nothing changed, so didn't think it was a relay problem. He removed some sensor on the passenger side on the back part of the engine and the fans got really loud and really fast. When he replace that, the fans would go back to normal until the engine temp got hot enough to turn them on and then they wouldn't go off again. He's thinking that sensor might be the problem, but isn't 100% sure. I think he said this was the cooling fan sensor or switch.
On a side note that may or may not be related. About 5 years ago the water pump broke. It started having the fans on all the time (even from a cold start), that turned out to be a faulty knock sensor. There was a knock sensor code and he replaced the knock sensor and then the fans went back to normal cycling. I didn't have any problems until early last fall, when I started noticing my current problems. I didn't worry about it until now, because as it got colder outside, it wasn't an issue. So outside temperature definitely effects it.
There are no codes this time.

Where to find shims for the ac clutch. They guy at O'Reilly didn't know what I was talking about when I mentioned an air gap for the ac clutch. He recommended switching out a sensor on the compressor. I have a 1999 F-350 7.3. with 266550 miles. I seem to be having a problem w/ my ac cooling for a few minutes then blows warm air then will blow cool again. All happening while never making switchs to the controls. I have read the other post regarding this issue and it seems to be the air gap is to wide. I backed out the screw in the center and then pulled off the faceplate of the clutch. Question, is the shim the washer looking item which was up inside the faceplate of the clutch? If so, how many are supposed to be there? I saw only one. This is the first time this has been opened up. And if there has been excessive wear, wouldn't the gap get narrower instead of wider?

I just got done changing a/c clutch on a 96 f-350 5.8 because it was making a lot of noise. The new one is just as bad. Would the air gap cause this? When I took it off I could see it was hitting the pulley. The gap was 0.21 is that the specs on it.

I have a 99 f350 7.3 diesel. The AC clutch cycles on for 3-4 turns and then off for 45 sec. It the does it again. The low side starts to cool down and then the clutch quits. as the truck warms up the clutch quits completely. it will restart for a few times if I push in on the elec conn on the ac clutch. My Ac has quit cooling and summer is almost here.

So I have an 02 f350 and I just recharged the ac system today. At first the clutch wouldn't engage, I tried tapping it and nothing. Then when I went to pull it out of the garage I left it in park to close the garage doors and I could hear it locking and unlocking.
I checked the voltage at the plug and am barely getting half a volt but it still doesn't lock up when I apply direct power to it. I didn't mess with the shims because I do not believe that to be the issue.
After I had shut the truck down and started it back up the clutch wouldn't engage at all. Do I just need to run the system or what? Its working just not consistently, I was thinking the oil needed to be recalculated a bit.

I'm getting a random 'no start' fault which I think is related to a clutch position switch. The dealer tells me the clutch pivot bushing and master cylinder push rod are worn out, which is causing the switch not to close when the clutch pedal is depressed.

I recently replaced my Ford Factory clutch with a new LUK kit, lever, pivot & hydraulics and I have to say it is absolutely perfect. If you are going to take the time to do the clutch, do it all. While we had it apart, I decided to push up my Up-Pipe replacement and do it while the transmission is out. What takes several hours to do is done in 30 mins this way. As we all know when we start in a job, we see other things and say well while it is apart I may as well do this, and do that. I decided to do the U-joints in the rear shaft. I had marked the shafts prior to removal for orientation but my assistant did not mark all 3 U-joint knuckles when he changed the joints and reinstalled the shaft.
I took the truck out for a drive and starting at about 15 MPH all the way to 60 ( I dared no faster) it was making me nauseous. Today I looked into it, marked current locations and started rotating front and rear joint 180 to no avail. I said lets just rotate the center joint and go from there. as I was pulling the carrier i noticed a HUGE but dull yellow arrow on the short shaft. I decided to look at the rear shaft and found a HUGE but dull yellow arrow 180 degs from the front. It looks like it could have been a factory mark. I repressed the center u-joint so the 2 arrows line up and the vibration went away. I can not express the aggravation this could have caused if not for those arrows. Take the time to properly index the drive shafts, it will save you tons of time and agitation.

Here is my problem: A/C not blowing cold air, blower motor working fine, checked all relevant fuses for A/C and R202 relay under the hood. Everything is fine here. Next, low pressure switch, jumped, clutch does not engage. Next removed relay R202 (clutch relay) measured voltages (at female sockets) where pins 1 and 3 would go, voltage OK. Jumped where pins 3 and 5 would go (bypass to see if clutch engages) and it does. Appears that the pressure switches check out OK (low pressure and A/C cycling switch - although this one not sure). CarMD unit was used as well, and no codes generated so perhaps PCM is working OK? I'm stumped, as a loss of GND by PCM or perhaps a corroded or open wire issue??
Also, possible the A/C switch on the HVAC control could be bad, but the light comes on, (doesn't mean switch is good necessarily). The rest of that unit works fine, control ***** that is, fan speed adjusts properly, air flow looks good. It appears this is an electrical problem where the clutch is not getting juice but I don't know the source of the problem. However, I also noticed that when the clutch/compressor was running (temporarily as described above) cold air still didn't come out. This, I assume, would mean I would need to add refrigerant or re-charge the A/C AFTER I get the clutch to engage electrically. 2004 F-150 5.4L ....

I've observed that on a cold start first thing in the morning that there is a noise that appears to come with the depression/release of the clutch. This only occurs the first couple of times and then goes away. My drive is down a hill with speed bumps so the clutch gets used a couple of times shifting down from 3rd to 2nd. After the third/fourth/fifth depression of the clutch the noise goes away.
The car as of now only has 140 miles on it. My daily commute is 2.5 miles each way.
I've emailed the Ford dealer from where I purchased the car, but had no response.
Sounds like the clutch release bearing to me.
