SWMBO's Grand Prix started having a problem a few weeks ago. The climate control module started being unresponsive (no fan at all, no A/C light, no temp changes, nothing). I checked all of the fuses and everything was okay. I pulled the module and looked for any faults; there weren't any. I bought a new GM module and installed it. I worked perfectly in the garage post-installation. 3 days later it is also unresponsive most of the time. If you cycle the key off and back on it will sometimes return to working fine.

Any suggestions?

I hear that this is fixed with a new ignition switch. I have the same issue with my Olds on the same platform.

These cars seem to have a lot of electrical issues as they age.
