Ford Super Duty (1999-2016) :: AC Stopped Blowing Cold / Clutch Clicking On And Off
Aug 16, 2015
2002 F350 with V10. A/C stopped blowing cold. I can hear the clutch clicking on and off, so probably needs refrigerant? Other thing is that with A/C off, the temp control turned to cold, and fan on, it blows hot air. On my other vehicles with A/C off and temp turned to cold, I get outside air at ambient temp.
I removed the cover off the evap core under the dash and observed the blend door opening and closing as the temp selector is moved. The duct door moves correctly, so am I'm missing something? Is the Ford system such that ambient air is always heated? This happens even in cold temp conditions.

Background : 2002 Excursion 7.3L, 320k miles ...
AC was working OK, but not great. Then AC stopped blowing cold at all. Checked pulley, gap was huge, but pulley bearing was completely destroyed. Like, 1/2" wobble, half the ball bearings in there. Amazed it hadn't seized. Replaced pulley, set air gap to bottom of the spec.
Air seems to blow kinda cold briefly, then fades to no cooling after a couple minutes. Same at idle or moving. Front and rear both not cold. Lines in engine bay are cool, but not real cold
Compressor body feels hot, like...right at that threshold of too hot to touch. Don't have pressure gauges, but will buy/borrow some and take some readings.
What would symptoms of a clogged orifice tube be? What would symptoms of a clogged condenser be? If low on r134, I could refill, but any tips on chasing down leaks?

Got in my truck this morning and everything worked fine, no problems. Arrived at my destination and parked. Come out about two hours later start the truck and my A/C wont blow air, My truck is an 05 lariat so it has the climate control A/C. Everything was working fine it just wont blow air, When i turned the A/C on and off i could hear/feel the small thump of the clutch engaging on the compressor. I am thinking the blower fan just went south? or maybe something stupid that controls the blower fan? Summer is in full swing here in central florida, temps are 95+ not including the humidity...

I think the truck needs a recharge, it's not blowing any cold air. The question is - which port do I use? There's one on the top of the accumulator and another in the line just off the passenger side of the radiator, near the coolant tank.
My only recharge experience was after I replaced a leaking accumulator in my 2007 Crown Vic police interceptor, and this obviously doesn't look quite the same.

Here's what's happening:
I can have it on hot and be driving along, then it will start blowing cold air. I can move the temperature switch to cold then back to hot, and it'll start blowing hot air again.
Need to know if that would be temp or the motor? I don't want to just change parts randomly.

This week was our first nice week of the year. Monday I got in my truck at lunch time turned the a.c. on and it blew ice cold. Today my truck sat in the sun all day and I got in it and turned the a.c. on. I noticed instead of the normal "click" you hear when the clutch engages in the a.c. compressor I got a wine and wimper kind of noise. The system never cooled the air after this happened. Is the compressor shot? Is it safe to drive or is the compressor going to tear itself up and send metal pieces thru the system?

My '01 Super Duty 5.4 has an overheating/heater problem that the dealer can't seem to fix. I noticed my heater was blowing cold then a few miles later it overheated pushing coolant out of cap. Next day drove fine to Ford dealer who replaced my heater core, thermostat, reservoir cap and a hose. Drove it for a day till the exact original symptoms occurred again with a gurgling sound in dash. Dealer kept for a week pressurizing system but no leaks found. Replaced my thermostat again and gave it back. I drove it 300 miles over a week before the exact same symptoms occurred. Brought back to dealer who said that air was in the system, added a bunch of coolant and supposedly got all the air out. Same symptoms still. Brought back to dealer that finally changed the water pump they said had a leak. Guess what, same symptoms. Heater will work fine for days then it will blow cold, then hot, then cold and sooner or later truck will overheat then just as fast cool down and heater will work again. Still hearing gurgling. Dealer said I don't have a HCV.

2008 F-250 Lariat with EATC climate controls... My truck suffers from the knocking/buzzing/clicking that is apparently associated with faulty blend door actuators. I have been putting off getting them replaced because of the hefty price tag associated with tearing apart the dash and whatnot that is required to get to the lower actuator that sits right on the transmission tunnel. Anyhow, today was the first day I really needed A/C and it just wasn't cold. Cool yes, but not cold. Is there a way to determine if this is a function of the blend door(s) not doing their thing versus the system A/C needing a repair/recharge? I don't have access to any A/C equipment myself, how to determine if it's a blend door issue?

this doesn't make any since to , what's going is, sometimes the AC starts blowing warm air, I found out if I goose it I can hear what sounds like the damper door slamming shut, then AC starts blowing cold again. I changed out electric vacuum pump, but it still does it, starting to get worse & its hot.
Truck is a 2002 f250 powerstroke, the way I understand it, is only thing vacuum pump is supposed to control is AC & 4 wheel locks, my truck is only 2wd. I don't understand why when when I goose it ,it goes to working, what can I do to fix this.
I just found out the " heat and cool "adjustment is electrical, not vacuum, it goes to something under dash, but what it is, heat strip, reastat(sp)??? where and what damper am I hearing. It is not like heater is on ,not that hot, feels like ambient temp, I am at a loss...

I have followed the vacuum lines but don't see any holes or cracked lines. I dont have the ESOF hubs so that is ruled out. Also checked the connector on the vacuum pump to make sure it still had power. Everybody says that when I turn the key to acc I should hear the vacuum pump running. I don't or do I feel it moving. Am I on the right track? I don't want to replace if not bad. Do all vacuum pumps run on keyed power? I honestly don't remember hearing it run before but that doesn't mean anything with my memory.

My problem had been intermittent for last few days. I have a Ford Crew Cab - 7.3 Powerstroke Diesel. The ford store told me it would cost hundreds of dollars to chase this short- to wait til it finally burns out then - bring truck to them.?
My fuse # 45 a 10 AMP fuse . Keeps blowing out. This fuse controls the gauges on dashboard and fuel peddle. I can start engine and if gauges come up like they should- I can place into driver - and give engine fuel from peddle- gauges down dead and no fuel go to motor. It just idles and still runs and will still move forward or backward. But only at idle speed.
I could replace blown fuse - #45 - 10 amp and it would a the first few times would go and work normally.
Now everytime I replace fuse it blows fuse - sometimes after putting 10 or more fuses in- one might work until I stop or put into park. Then fuse blows again??
Last night and today it took no less than 20 - 10amp fuses to get close to home and end up straight wiring with a small piece of electrical wire - severing as a jumper- it ran great - til I stop at mail box and got mail - saw slight smoke and pulled wire quickly out and idled down driveway to house..

I was driving to work this morning and my hydraulic clutch linkage messed up on the 1999 f-250 super duty 7.3 with zf 6 speed. It acted like any clutch master cylinder when they go out, the pedal went to the floor and the clutch would not release, but it also became very hard to shove in the clutch pedal, so I speed shifted it without the clutch and made it to work. So I figured no big deal I will swap out the clutch master and slave cylinder complete assembly in the parking lot, except I had to get a ride 30 miles to an auto parts store that had it in stock. I changed out the complete assembly and same problem with the new one, extremely hard clutch pedal, so I did not dare to push it anymore and risk damaging the new cylinders, and left the truck at work. I am thinking broken throw out bearing jammed into the clutch, or dislocated throw out arm causing the problem. The clutch disc, pressure plate and single mass flywheel were replaced by the previous owner 3 years and 15,000 miles ago.

I have 2002 F250SD, The horn just starts blowing by itself. Bump the horn switch and it stops for a couple of weeks. I've looked at the wires to the fuse box and no wires shorting out the horn wire. I read some very old posts but nothing conclusive was ever decided on, just a lot of guessing. The horn switch has always been sensitive.
Somebody said the air bag is warming up in the sun and expanding causing the horn to blow. Somebody said the horn relay, but in 55 years of working on trucks, I have never had a horn relay act like that. I'm told the horn relay is built in the back of the fuse box and it all has to be replaced. Some say the clock switch. I don't know what that is or where it is. I guess inside the steering wheel. Is it hard to replace?
Where do I go from here....

Sitting in the house, heard a horn blowing and ran outside to find my F350's horn was blowing. When I pushed on the horn button on the steering wheel it quit. Couple of hours later, it started blowing again. Pushed the horn button to make it stop and removed the fuse so it would not start blowing again. Did a forum search, but didn't have any luck. Short in steering wheel?

It controls the auxiliary powertrain control module (diesel only),Instrument Cluster, GEM Module, Overdrive Cancel Switch, Idel Validation (Diesel only), Overhead Console and Diesel PCM via Clutch. I would like to know where to start looking to solve this problom.

My husband and I have 3 Excursions, V10, 6.0, 7.3 and I have a 6.0 250 crewcab. 3 of the 4 now blow air or heat from just the defroster unless your going at a slow speed.

Got a little wild while i was in the trails the other day and was bouncing pretty hard and my headlight blew. Well now im on my third one and id suspect a short. This time it blew the bulb right apart so it must have got pretty hot. Any common problem areas i should look into before trying to figure this out?

Not sure what this component is but when I wiggle the wire at the orange cap a small motor kicks on.
