[Peugeot-L] 405 DL AUTO - COOLING FAN & AC ISSUE

The cooling fans come on at high speed at too low a engine temp when the engine is not overheating like at 170 F. They are not on initially on a cold start. Is this a relay issue or erratic grounding issue. I've looked at and cleaned the grounds near left headlight. The grounds looked in great shape. I looked at the cooling fan relays (in front of fans) last summer. They did not looked corroded and I put a dab of dielectric grease on terminals. No change in status of problem

Another issue, maybe related maybe not is my air-conditioner compressor won't stay engaged due to some erratic electrical problem. I had the the R-12 pressure checked and it was fine but the compressor clutch engagement is erratic due to some electrical glitch. A local mechanic who checked the R-12 pressure said he couldn't look at the electrical since he did not have the electrical schematics. I have a Peugeot electrical manual but hardly know where to begin.

No, I don't need the AC now but this is a carry over problem from summer and if I don't get it fixed for my daughter I need to buy a car is fewer glitches for next summer.
