So my last a/c compressor took a **** on me and i had a 04 sedan compressor laying around. I installed it and everything and had the freon vacuumed and charged. I go to turning on the A/C but the clutch on the compressor doesnt engage and is still blowing hot air. I look for an A/C fuse but there are none. The technician at the shops tries checking up on his manual and says that a computer over rules it. He suggests me taking it to the stealership but im sure its real expensive. BTW my car is an 03 coupe

 

check the wiring going to the compressor, make sure it's plugged in for a start since you swapped them, if it is try back probing and checking to see if you have power there. There has to be a fuse somewhere just might be under another option.

 

sounds like u need a shop

 

daym! I was hoping to come in here to find an answer. hahahaha

I have a different problem. I got into a car accident and the clutch to the a/c compressor fell off.
I want to buy a clutch off of the internet and slap it back on. Hoping it'll work.

 

yeah almost positive theres an a/c fuse in the fuse box behind the battery. how did you make out? and you said you have a coupe and you put a sedan compressor in?? did it bolt up okay?

 

i finally got it fixed about a month ago. But it was really just a 10 amp fuse in the IPDM box behind the battery. And yes the sedan compressor bolted right up to my coupe. However the coupe has 4 mounting bolts and the sedan has 3. Runs perfectly fine for me though

 

great thank you very much

 

ill be installing my sedan compressor to my coupe wish me luck

 

just make sure you empty out and install the compressor oil. Goodluck!
