2010 Nissan Altima AC cooling fans not coming on until the engine is hot, then work fine.
My wife complained that the A/C wasn't working so we dropped it at a trusted
mechanic. He worked on this for a while and advised the following. He is
stumped. The A/C cooling fans do not engage when the A/C is on UNTIL the
engine is hot, Once the fans come on the pressure drops in the system and
the compressor will engage and the system will cool as advertised. Once the
vehicle is at operating temp there are no more issues for the rest of the time.
Once the engine cools (like over night) we have the same issue until the
temp rises on the car. I'm suspecting a thermostat or temp relay of some
sort. He stated that this might actually be a programming issue.
