AC not working after alternator replacement...

Asked by Aug 28, 2013 at 09:44 AM about the 2005 Chrysler Town & Country Limited

Question type: Maintenance & Repair

I have lost all faith in the garage I am going to.  I had an alternator replaced and now my air conditioner isn't working, specifically blowing hot air.  There is plenty of refrigerant in the system.  It worked fine when I brought it in.  The garage is now telling me I need a new PCM because it is not turning on the AC as well as a new AC clutch because every time it tries to engage the clutch, it blows a fuse.  If the PCM is not sending a signal to the AC then how can the clutch blow the fuse?

Does this make sense to anyone?

I can agree with it might need a clutch/coil assembly, that is what is blowing the fuse, but as far as a new PCM I am skeptical normally the PCM just activates a relay witch in turn activates the unit. I would find another shop.


the compressor is just under alt. look and see if mabey it is unplugged.
