RE: My Pete rebuild
Any Pete electrical guys on here? A couple of weeks ago, my fan kicked on for no apparent reason. Then it did it again. I pushed the a/c button (I had my heat on defrost/floor as usual) and it changed pitch/seemingly fully engaged the fan. Pushing it off, and the fan got quieter, like it was letting the clutch slip. I ran the trip just leaving the a/c button on and it didn't do anything strange until this week. Even with the heater controls completely off, it was kicking on randomly driving down the highway (temp reading 180-185 as usual, oil temp in the 210-220 range).

It's completely random, I can't really run with the laptop on to see if I can catch what is triggering it. By the time I'd wake the computer up, get blinded by the screen and die a fiery death, I probably still wouldn't be able to see why it's calling for fan lol.


I hate sporadic and random issues, thus I'm getting ready to fire up the parts cannon.

I picked up a new HVAC control panel. My thought was possible feeding/bleeding signal from the funky a/c switch. CECU is a $1500 possibility, and so is a rubbed wire. My question, is the ECM the only final say for engaging fan? If so, how many different input signals does it read, or does everything but the temp sensor go through the CECU before the ECM?
