Ford F-250 Super Duty Air conditioner not working

I have a problem with my AC in my truck. When I first start up it works fine. After driving a while- especially in stop and go traffic on a hot day the air will become hot. I have checked under the hood when this happens and the clutch on the compressor seems to be not engaged. I checked for loose wires but did not find any. I tapped the clutch with a hammer and the clutch engaged and air worked fine. Can clutch be repaired or replaced and can it be DIY?

Do you
have the same problem?

Hi. I own a 2003 Ford F-250 Truck, with a 6.0 Turbo Diesel Engine. It's a 4 x 4 with approx 92000 miles. The A/C is not working, so opened the hood and noticed the compressor is not engaging. The fuse is ok, so I thought it might just need to be recharged, so I bought an artic freeze R134a kit. I hooked up to the low pressure side, and the gauge said the system was overcharged. Any Ideas as to the problem? Thanks in advance for any help.

Howdy. Thanks for your response. I did as you instructed, and here's what happened. When I disconnected the switch, I noticed a slight engine rpm decrease. When I jump across the 2 wires on the connector I get a slight increase in rpm (same as with the switch connected. Nothing else changes. No compressor rotation, or fluctuation in pressure. (Note: I have verified that the compressor turns easily by hand). Thanks again.

Hello again. I started the engine, turned on the A/C, climbed under the truck and tapped on the compressor hub/clutch assy as instructed. The clutch is still not engaging after much tapping. I did notice that the clutch assembly seemed pretty wobbley inside the hub. I understand they have springs inside to aid in dissengagement, but I was surprised that the springing action was as light as it is. Does this sound normal?

Howdy. I crawled back under the truck, and verified that the compressor rotated freely. I checked for side to side movement, and didn't find any, but. I did notice that the front plate seemed to move fwd a little as I jiggled it. I pulled it fwd as I wiggled it, and it came completely off in my hand. Turns out that the retaining bolt has fallen out. Do you suppose that if I put in a new bolt it will work?
Thank You
Darrel.

Howdy. Stopped by the auto parts store, picked up a 6mm-1.0 x about 3/4" long. Installed the clutch plate. Installed the bolt. A/C is now working flawlessly. Wish I would have used a mirror and noticed the bolt missing a couple of months ago. LOL. I'm just happy to have it working, and even more happy that the cost was under 2 dollars. Thank you for all your wise counsel. I am now cool.

Heater problem
1977 Ford F250 V8 Four Wheel Drive Automatic 108700 miles

what needs to be fixed? Does it have a control valve? The heater core does not leak and the hoses going to core and back get warm.

Check and test the thermostat and check if heater core is clogged

I have a 1995 ford f-250 super with a 7.3 litre diesel engine.
The ac has"nt worked since I got it so I thought it might be a matter of just charging it so I went to kragens auto store and bought the r-134 ez charge with the gauges.
Followed the steps by putting the hose on the low side and filled it untill the gauge showed me when to stop. Its holding fine at that position so there is no leak but the ac is still not working.
How can I check the compressor to see if it is working? Or have you any ideas as to what is wrong.
Thanks alot

I had power at the purple wire so I crossed the purple wire and the other wire like you said and I could see the compressor kicking in.
I can"t tell if the ac is cold or not cause its actually cold where I am today but this definitely made a difference.
As soon as I put these wires into there proper place again the compressor would click back out again and stop.
What does this mean?

Followed your steps.
Before I jumped the two wires the gauge read 25psi.
When I jumped them it went straight to zero.
I filled the system up to 35psi and I re-conneced these wires in there proper place and I notice now that the compressor is cutting in and out every couple of seconds. :) I checked the gauge again and ts holding steady at 35psi
i live in sf city and today is windy and cold so I can"t tell if it is blowing cold or not cause when I switch to vent it seems the same.

Did that but compressor is still cutting on and off and can of freon is nearly empty. When it cuts off its reads about 35psi and when its comes back on it drops to zero. Also I notice like water dripping out from under it. Maybe there is a leak in it after all?

Hello. You are a life saver.I did that today and the ac is 100% now. :) Thank you so much.
The cruise control is also giving trouble.
Its works fine in the morning for my 1 hour drive but I have nothing when I come home in the evening. The hooter also stops working when the cruise stops.I park the truck over night and jump into it in the morning and its fine hooter and all. Would this have anything to do with temperatute?

Hello. No the airbag light does not come on.
I took off that connector at the front of the master but there is no change so far, the cruise control and hooter would not work on my way home but it will work again in the morning. Weird.

Air Conditioning problem
1996 Ford F250 V8 Four Wheel Drive Automatic 110000 miles

My A/C was running really cold (as in freezing) until yesterday where it stopped running. Hot air came out the vents after the engine warmed up. The fan is still going and when turning the switch to A/C I can hear the air valve changing position? I have checked the fusebox and the compressor belt is OK. Also it does not go into defrost position.

How do I troubleshoot the problem from here?
Thanks

Hello -

To better assist you please tell me your engine size in liter and the 8th digit of your VIN. Please go to Auto Zone (AZ) or O'Reilly's (OR) and for FREE they can pull the codes to the car. Most important: Once they check your codes, if they find something and you don't get it fixed and need to get back with us, please make sure you tell us exactly what the code was, number and all. Example, if the code was E0568 O2 Sensor bad. Then make sure you give us all of that. While there for FREE also they can bring their tester out and check your battery and alternator.
