Ford Superduty A/C Problem

PMAC — Thu, 19 Mar 2009 23:41:38 GMT

Hello to all...

I'm having a problem with my air conditioning on my 2002 Ford F-250 Superduty (Powerstroke 7.3L). I'm hoping it is not a big problem as the economy...well...you know. I have never had any work done on the on the air conditioning system for the truck in the almost 8 years that I have owned it. Last summer, it started having issues. When the truck is idling on hot days here in Georgia, or when driving but not "in the gas" (i.e. coasting or only slightly giving the accelerator pressure), the air conditioning blows only luke warm to warm air (not really hot...more like the outdoor air temperature). When I press the accelerator pretty good the air conditioning blows cold air. At night or in the morning when the outside air temperature is lower the problem is not as noticeable. Of course, it could be that the problem is the same morning, afternoon, and night but that it isn't as noticeable in the mornings or the nights because the colder air isn't needed as much.

I'm not likely not skilled enough to fix the problem no matter what it is, but I am hoping that I might get an idea or two as to the likely problem so that I know enough not to get abused by the service person when I go to get it fixed. Any assistance would be greatly appreciated. Thanks.

False messages on computer screen and A / C compressor being turned off

RRJ — Sat, 28 Jul 2007 05:07:54 GMT

Have 1989 Buick Rivera with the 7in. CRT screen and it gives message A /C is low on Freon and compressoe is being shut down, but if you touch screen where it says Return the compressor stays on, other wise it turns off and you have to disconnect the battery and reconnect to get it back on. The screen also gives message that the engine oil is low and the coolant is low and engine will be damaged if the engine is not shut down. Three electral shops have been stumped as to cause.

Bravada A/C problem

stuey1 — Sat, 29 Sep 2007 17:17:36 GMT

The a/c on my 1999 Olds Bravada has a mind of its own. When it works it works fine ..plenty of cold air...goes where directed. Often, when i hit the a/c switch, the switch light blinks 3 times and the a/c does not come on. After driving between 1.3 and 1.5 miles it comes on and works fine. Two days in the shop (not a dealership shop) and no solution. On cool mornings it seems to work fine. HELP!

ac compressor icing up

korynmae — Tue, 02 Oct 2007 06:20:00 GMT

the other day, while driving in the snow, our heater quit blowing, but we could hear it trying. when we stopped to check the hoses, the ac can was all iced up, and by the time we got home, the plastic housing over the heater core (inside the truck) was also iced up. after we let it sit and thaw, every thing worked fine, for a bit. then the same thing all over again. please, someone tell me this is something simple. if it makes any difference our truck is a 03 dodge ram.

I have just replaced the high pressure hose on my vehicle due to a leak. It is a R134a system and I know what type of oil to use. Can anyone point me in the direction of somewhere that has some good info on evacuating the system so I can refill it with new refrigerant?

92 Jeep Cherokee - A/C Problem

eagle601 — Fri, 13 Jul 2007 22:15:51 GMT

I been having a problem with my jeep overheating only while the A/C is running. I do have some knowledge of automotive air repair. So what I have is a compressor that is not cycleling, it stays engadged.Building a high head pressure, which is causing the condensor to get very hot in turn not allowing the radiator to cool the engine efficiently. Could the problem be a high pressure switch.

'94 vette(C-4), clutch does not engage consistantly.However an light tap of hammer "handle" and the clutch engages and may operate normal for an hour or more.Only a gentle tap is needed to cause engagement.
May the clutch "only" be replaced without disconecting the Hi&Low side refridgerant lines?

1995 chevy astro bypass ac

lolaKLC — Sat, 23 Jun 2007 17:18:34 GMT

My air compressor has blown on my 1995 chevy astro. I can live without the ac since I don't want to put big bucks into replacing it in an old vehicle. My question is if possible how do you put on an ac bypass pulley, do you have to take out the air compressor??? Otherwise would it be better to replace the belt with a shorter one and how would you route it???? thanks

2000 Pontiac Grand Prix Compressor Clutch Not Engaging

markd — Wed, 20 Jun 2007 02:24:02 GMT

Just recently the A/C clutch stopped engaging on my 2000 Pontiac Grand Prix. The clutch freely turns and the system is fully charged. I don't have a repair manual but I did find the Clutch relay and reseated it but no luck. I also check the connector at the compressor and all looked good. I am trying to determine if I have an electrical problem or A/C clutch problem. Is there some check I can make with a volt/ohm meter (resistance or voltage) on the 2 wires connecting to the compressor. Any help or diagrams are appreciated.
