Needing a wiring diagram for the cooling fan under the hood. The ones I’m finding they just don’t match at all. It has a big brown big red/blue wire and a real small green/black wire. I checked the power and ground with a headlight bulb. Scoped the small one had a square wave. It changed but the fan was running so slow and quiet even with the air conditioning on

The Mitchell one I was looking at to. The 2nd one you sent is correct. Where did you find it?? The fan controller is bad I believe. It just runs at a wimpy low speed doesn’t seem to increase speed with air conditioning or temperature raising.

It's got a horrible interface for entering year and model.
