I have a 1999 Winnebago Motorhome on a F53 Ford V10 Chassis and the A/C clutch will not engage when turning on the A/C. I have check the Freon 134A and it appears to be fine (in the red zone) and actually put a jumper across the pressure switch connector (harness side) and it still will not engage. Is there a fuse within the circuit if so, where it may be located?
View 1 RepliesOn my 2001 Excursion the ac clutch went south over the weekend. I replaced the clutch with a factory clutch kit. Now the problems are baffling me.
I set the air gap at .020. The problem being when I turn the ignition switch on and turn on the ac switch the clutch does not engage. I still get cold air. When I start the truck and it runs the clutch is engaged without any problems, I turn it off and the clutch disengages.
So clutch doesn't engage and compressor is not running. I have 12-13v at the low pressure switch and the same at the high. When I jump the low pressure I don't get any voltage at all at the plug that controls the relay for the clutch.
Where I'm confused is:
Is this a low pressure problem - gauge is reading 60psi on the accumulator
Or
Is this electrical somewhere?
I recently purchased a 2003 Grnd Marquis that has EATC climate control. It was a cold day, snowing some and the heater was set to 72 degrees on floor/defrost mix. Several days later it warmed up to over 40 degrees so I decided to try the AC. When I switched over to Max AC, I still only got airflow through the defrost. Any airflow setting (floor, vent, AC, Max AC) only gets airflow through the defrost. Also, the AC clutch did not engage when I set it on Max AC or it is not engaged when set on defrost. Will replacing the EATC head unit fix it? Is this also why the AC compressor clutch does not engage?
View 2 RepliesThe patient: e99 F250 Super Duty with 7.3 "Million Mile" motor, 350k miles.
Symptoms: AC won't engage, low pressure PSI reading is over 85, past my needle's capability.
Story: Bought the truck and found a big fat rock hole in the condenser. Swapped condenser and dryer, vacuumed, oiled, and recharged the system. Worked great for 1 month. Now seems any time I turn the truck off or turn off the AC it sends the low pressure soaring above 85 PSI. If I "De pressurize" the system to normal, Turn the truck on, then the clutch engages, and things go back to normal, then below normal because I just depressurized 2 cans worth of the system. Add two cans and it's good to go.
I just picked up a '94 7.3 IDI Turbo, and I can't figure out what ails the AC. It appears that there should be enough refrigerant (according to my recharge kit), but the compressor clutch will not engage. I have checked the fuses, and all are fine. All other HVAC functions are normal. Is there a way to test the compressor?
View 5 RepliesSometimes in the morning the AC will work just fine, but after a while it stops working. It looks like the clutch will not engage and I don't know how to troubleshoot it. I'll take a picture later on today. I'm wondering which part is what, and what might be causing the problem.
View 9 Replies1999 Ford Ranger 2.5L 5 speed transmission. I am a little confused I can not get the transmission to engage the clutch, I replaced the clutch 3 weeks ago, now I have no pressure in the pedal, I have bleed the system 5 attempts with clean solid flow of fluid. What else can I do to fix this or trouble shoot from here?
View 6 RepliesSays A/C Compressor Clutch Circuit open. A/C blows hot air....go to VENT and the EATC controls the temp fine (ambient air only). It's on a '97 Lincoln Mark VIII if it makes any difference. Pulled code # 1530 ...
Clutch does not engage but the compressor does turn. Also the EATC will NOT go into the test mode. Push OFF and Floor at same time, then AUTO within two seconds. Nothing. Is this a clutch gap problem? New clutch was installed about a year ago.
I have a 94 Ranger with 2.3L motor. Last week my ac quit working. I push the in and the ac light goes on, but the compressor clutch won't engage. I changed the relay, but that didn't work. The fan still works, but the ac does not come on. I tried banging on the compressor pulley, but that didn't do anything. The clutch is not frozen -- it spins freely. The connector looks good and I haven't done any work in the engine compartment so I couldn't have accidentally moved any wiring. What I might try or is my compressor simply dead?
View 2 RepliesI have a 2001 m5r2 ford f-150 standard transmission. i have replaced the slave cyl., the entire clutch assy., the master cyl. pilot bearing. the trans. will engage all five gears plus reverse while truck is off but will not engage a gear while running. i have bled and bled and bled and still will not engage.
View 1 RepliesThe A/C in my truck stopped working last year, and this year I intend to fix it. I believe the problem is with the compressor clutch because it was making noise as it would engage or disengage. It was making this noise for a good year or so, and then one day the noise stopped and I have no A/C. So I am only assuming its the clutch.
View 4 RepliesI have a 1995 Ford Windstar. When I turn on the air conditioning, the compressor clutch does not engage despite having sufficient refrigerant in the system. Jumping current directly to the compressor clutch will engage the clutch, so it's not the clutch. I suspect the relay for the compressor clutch inside the CCRM may be bad, but am not sure how to test it. I have a Haynes repair manual, but how to test this device?
View 12 RepliesI have a 1995 Ford Ranger 4 cyl w/ hydraulic clutch, about 95k miles, and an intermittent problem. Normally, my clutch works fine, but a few times a year, normally during the summer, and normally only after driving for a half hour or more, it starts to act up. First, the pedal starts to feel a little spongy. Then, I'll depress the clutch, and when I release it, the peddle comes up, but the clutch does not engage; a few seconds later, the clutch engages fully instantaneously, which usually stalls the engine if I am stopped.
Then, when I try to reengage the clutch so that I can restart the engine, the clutch is very stiff, and I have to pump it a few times, at which time it will depress easily, and then I am usually back to the original problem where the peddle comes up but the clutch does not engage. When I finally make it home and the truck sits for awhile, the clutch then works fine again. I think it is the orig clutch. I have talked to several mechanics about this problem (including the Ford garage!), and they are mystified. One mechanic thinks that it is a problem with the master and slave cylinder combo, and can replace them.
So I just had my entire clutch replaced while another repair was taking place. What I've noticed is the "clutch engagement" has changed. Where as I would have the clutch start to engage/disengage at the 1/2 way point on the pedal travel is now the last 1/4 of the pedal. Is this a "normal reaction to a new clutch that just takes getting used to or is there an adjustment I can fine turn it with? Do I just have to wait for it to "break in"? When I replaced the clutch on my dearly departed 94 ranger, I replaced the bearings & disc only reusing the pressure plate and did not have this issue.
View 3 RepliesMy daughter has a 2003 Saturn Vue 2.2 and it seems that the clutch if froze up... I have checked Freon level with a gauge that I use to top of Freon and seems ok... the vehicle has 170,000 thousand miles... are these compressors prone to failure and is there a "Quick Fix" without replacing compressor, orphis tube and dryer?
View 3 RepliesI traded for a 99 passat 1.8t aeb based on the assumption the slave cylinder was out. My 3rd b5 5 speed. Kid told me clutch pedal had no pressure and fell to floor.easy fix! Get the car to my house from 2 hours away and this is not the case.Pedal is fine. Decent clutch pedal starts with clutch pushed in. But clutch does not engage. Even when motor off or on goes into all gears without clutch pushed in. no engagement. So I put in new slave and bleed out.
Car no longer stuck in neutral shifts fine. Put in reverse barely crawls but is MOVING! Put into first and start to pull forward..stops moving. No clunks or booms just back to ALL neutral. starts with clutch but wont engage. So try bleeding again nothing.. I think it is the clutch but i dont want to spend 1400 if i dont have to though the car is worth it. Going to replace dual mass as well. The cv joints are fine. so thinking throw out or pressure plate. i work on this car like crazy but im definitely not going to do the clutch. Not enough time or a warm dry location. I haven't checked clutch master yet but with slave bleeding out,no leaks and a firm pedal i dont believe she is the culprit..
if the fan doesn't work, could this make the AC compressor clutch not engage? I think the fan is burned out because it doesn't spin at all, and only moves with a lot of effort. If the fan circuit is open, will this cause the Compressor to not work as well? the car is a 1991 740 GL. 2.3L engine, non turbo.
View 3 RepliesI have a 2001 Ford ZX2 with 170,000 miles on it. The clutch pedal doesn't engage the clutch until it is almost touching the floorboard. I thought it had a hydraulic clutch being a 2001 but I can't find a reservoir for the fluid so now I must assume now that it is a mechanical clutch.
1. Does they hide the reservoir on these ZX2's?
2. What could cause the clutch issue?
My AC doesn't work right now, however, sometimes it works. It's very random, it doesn't matter if its hot outside or if its cool.
What happens is my AC clutch doesn't engage. when I turn ac on, it raises the idle for a second, and as soon as it does that, my ac compressor gets around 12 volts for less than a second, and the idle drops again. it does that in a loop.
My fans work fine, both high and low speeds, everything else works, all the fuses are good. I changed the pressure switch, didn't fix the problem. I also checked the ac coil and clutch. everything clicks and works. ground on the compressor is good.
Other odd thing - positive wire on the compressor constantly getting around 3 volts. What can it be and what else do i need to check?
148,000 miles, and yesterday my R decided it would no longer allow me to use first gear. It sort of starts to go in gear, but feels kind of mushy, not positive, and if I let out the clutch, the gears grind, but will not engage. All other gears feel and perform normally.
