Questions Re: PCM and AC

[BruceND75]

I have a 2000 Grand Prix with a V6 3800 Series II.

Recently had to replace my A/C compressor after several years out of service (moving to the high desert and open windows no longer qualify as A/C). Had a qualified mechanic/friend do the work.

Discovered that there appears to be a short in the PCM that provides ground to the fans associated with the A/C.

Note: everything else associated with PCM appears to be working fine.

Few critical questions:

Is it possible that the problem with ground to fans is a software issue in the PCM and can be solved by reflashing?

If not, can I make a straight swap with an equivalent PCM from salvage?

Would there still be reprogamming necessary to the newly installed, salvaged PCM?

If installed salvaged PCM, will car start and run enough to get me to a reprogrammer?

Wow, would any help on this be Greatly appreciated! I'm supposed to start moving next week, and dash is off and still-inop A/C is mocking my move to the desert!

What makes you think its a short in the PCM ?

ANd what fans are you talking about, the blower fan for the HVAC, or the radiator fans?
