Ok,

I know I've seen this mentioned before on this forum but suddenly my A/C with my power FC only works when the fan speed is set to high. I've searched the forums without any luck (my rx7club search waza must be weak right now). I'm guessing that the electrical contacts in the span feed **** are causing problems due to old age and/or corrosion but could somebody point me in the right direction on this problem? If this should have been posted to the power fc subforum then I apologize. It seems like I can only keep my car running 'like new' for a few months before some other gremlin pops up but judging by the other posts in this forum I'm certainly not alone.

Thanks,

Matt

 

What about the heater does that only work at high speed also? If it does than its most likely the heater relay. I believe its located behind the glove box on top of the blower.

 

The document contains the BEST A/C fix for the PFC.
It uses a very small Bosch 12V relay that can be purchases almost anywhere, at lease in Houston.
