The coil side of the relay stays engergized all the time when the key is turned on and if you jump it it will try to start the engine. also the fan is not controled be the A/C switch when it is turned on.
Thanks for any help you can give me. John

your fan sounld have a sensor in the engine that will cut the fan in when the temp get hot if that is gone it will come all the time or not come on at all check that first if no problem with the sensor then check the wires going to the fan for a ground

Suggested Repair

Check the engine temperature sensor that switches the cooling fan on when the engine is hot; a failed sensor can keep the fan running constantly. If the sensor is okay, inspect the fan wiring for a short to ground.

Conversation Summary

The owner of a 1993 Mercury Tracer with a 1.9L engine says the cooling fan stays on and eventually burns out the fan control relay. The relay coil remains energized with the key on, jumping the relay tries to start the engine, and the fan is not controlled by the A/C switch. The expert recommends checking the engine temperature sensor first, then the fan wires for a ground.
