    The thermostat is new, as well as the ECT sensor, and I did also replace the resistor and it only worked on high again. I am not sure how the thermostat would keep power from my electric cooling fans?

    thermostat does not have anything to do with eletrical stuff, it is just suppose to open at a certain temp 195*, 180* etc etc... depending on which one it is.

    I am too kinda confuzzed as to why it overheated. and the fans not working.

    I checked the two maxi fuses (30 amp) in the underhood electrical center, both good. I checked the leg labeled 85 on "cool fan relay 1", as schematic I have shows that should be hot all the time from fuse and I got nothing with test light. It shows the hot wire coming in through "cool fan 1 maxi fuse 30 amp" from the "power distribution cell 10" what that is I am not sure. Any suggestions? I see two wires coming from PCM that control Low and High Fan Speeds on schematic? Anyone.

    Yeah, you need to tap into one of those lines and apply 12v's to it. Doesnt matter which one. I would tag the line right at the fan, to eliminate any fuse or relay issue. If you apply 12v right at the fan and it doesnt come on, you need a new one.

    The power distribution cell is a fancy name for fuse box. Prolly the one under the hood. "Cell 10" Im assuming is the number given to that fuse.
