I have a 1985 Pontiac Trans am 5.0 H.O. Fuel injected with an automatic transmission that has a gremlin living in it. The car has a/c that doesn't work and a one electric fan unit. The issue is that once the motor is on the fan is on regardless of the engine being hot or cold, the fan stays on until I shut off the car. I replaced one relay and replaced the engine coolant sensor and the fan still stays on.I read somewhere that a/c T/A's had two fans, yet I have one, the relay that I replaced once pulled stopped the fan so I know I had the right one, but the fan still stays on. The check engine light is not on, what gives?
