1994 Mazda MX6 LS V6 - Cooling fan w/AC on question.
When I turn on the A/C, only the condensor fan comes on. I was told by an a/c repair shop that both fans should come on with the a/c. Both fans are brand new. All of the radiator cooling fan relays are new as well. I am trying to find out if the I possibly have a bad PCM. If I turn off the A/C, the condensor fan goes off. If I let the car get up to temperature, about 210 ish, the radiator fan kicks on and shuts off shortly after lowering the coolant temperature. Is it possible that the PCM is bad even though the computer is sending a signal for engine temp, but not to turn the radiator fan on for the A/C?
