Re: Cooling Fan Problem
The most obvious answer is the coolant temp sensor. Find a shop manual for the car and it will tell you how much resistance it should provide at certain temps.
Test continuity of the sensor body to the block. Sometimes they corrode and don't ground properly.
its also possible that the relay for the CTS is separate from the relay for the A/C turn on, etc. if so, the relay could be bad.
I say, bad CTS first, then look for other electronic mishaps like shorts, loose wires, etc.
