My a/c hasn't been working all summer. Finally hounded the mechanic at work here enough to finally look at it and he checks all the fuses and their fine and checks the electrical connection to the compressor. He said that was the problem was just the compressor not getting any power. BUT i dont have an owner's manual for the truck, so we couldnt tell if there was a fuse missing or something.

The air blows just fine its just not cold.

Any productive input would be appreciated

Thanks

Have you tried getting the AC recharged?

 

Yes that was the first thing i did. The gauge on the can showed it being overcharged

 

I did have the a/c running when i tested it with the "can", i didn't bring this up at first because i didn't think it was accurate. Today my guy unplugged the compressor and tried testing the plug and it didn't light up the fuse tester.


i assume i should do as you mentioned and "jump-start" it. What should i jump the terminals with?

 

tried what mark suggested and nothing, anyone know what fuse controls the compressor?

 

are you out of coolant?

i never run my AC so im just throwing out an idea.

 

Power for the compressor goes thru the cycling switch (on the accumulator). Jumper it and see if power gets to compressor.

If so, bad cycling switch or really low on refrigerant.

 

i have no owners manual.. can anyone point me in a direction of a diagram anywhere?

 

Low pressure switch is not getting power compressor not working.What fuse or relay controls power too these.No owners manual.

 

you can get a copy of your owners manual here:

I am having that problem but when it's pumped straight to the battery the compressor kicks in and blows ice cold. I checked both switches and fuses and relays and nothing. I was trying to get the color of the wire coming out of the PCM to see if i was getting power there but nobody could give me the info just telling me to check my relays more.
