Problem started when motor got too hot and then ac compressor broke.
Previously the car got jump started incorrectly and 60A fuse was blown.
Replaced the compressor-dryer/condenser, began filling Freon. Compressor came on once gas entered, but cooling fan was not on. The AC switch was on.
Direct power to fan and that came on, speed controller replaced, but still no
fan. I eliminated the AC by keeping it turned off. I let engine idle til she got 230*, fan still not coming on. Turning on the AC switch does not turn the fan on, so How do I diagnose the circuitry? (ect or relay). I have power and ground at the harness side of VSC (veriable speed controller) so Iam thinking no voltage at white signal wire. How can I trick that?
