I replaced the ac compressor on my galant and now the cooling fan and ac fan running as soon as I turn the switch on and run about 15 seconds after switch is turned off

since you just changed the AC compressor check to make sure all wires and plugs are ok and positively connected especially the one to the ac pressure switch...if it not found there then definitely check all coolant system related sensor wires grounds plugs on the eng and radiator for any damage ...good luck hope this helps

also on this car it should have cast a code for there being either a bad sensor or conection or a non communication problem if you have access to a scan tool that might help good luck
