Hello,

I am having issues with my radiator fan. It will not turn on even though the temperature gauge almost hits the top line. I also cannot get the fan to spin when I turn the AC on. I can tell that the compressor is coming on because the car’s RPMs drop a little. The air coming out of the AC is not cool either. The engine seems like it’s going to over heat if I don’t get the fan to spin while I am sitting in traffic. I have done some troubleshooting already and these are my findings and...
