AC electrical problem

[RJ237]

I replaced the AC compressor in my 04 coupe, but can't get it to work. The system is holding pressure, clutch works when external power applied, pressure switch appears to work, and no errors when I run the self check. Are there schematics available for the 3200 electrical system and is it likely to be much the same as the 4200?

There’s details in the worshop manual for the 3200.

Have you checked the outside temp gauge reading?

 

[RJ237]

Outside temp reading okay. Is the 3200 manual available as a download or disk? or do I have to buy a hard copy?

 

[Oneball]

I had a hard copy. I think you can get both.

Does the light come on in the ac switch when you press it?

 

[RJ237]

AC switch? I don't think I see that. No mention of a switch in the owners manual, but there is the ECON button that turns the AC off. That is not lit.

That’s the button I meant. Does the light come on when you press it?

Pressure valve? There is a low and high one from memory. If they fail they stop the compressor/system from kicking in.

Oneball- yes the light comes on, conaero, I might have missed something there. I checked a valve at the dryer, which I assume is in the high pressure line, not sure where to look for the other one, will search on Thursday.

Thanks for the assistance, gentlemen.
