I have a 1996 Ford Escort LX 1.9L engine. The A/C is blowing hot air. I noticed that the auxillary fan is not running. I read an article that said to remove the old relay for the fan and put in regular relays in. I have completed that task. The fan is still not running. So I head to the auto parts store and they tell me that it could be the low pressure switch and low freon. So a new low pressure switch and a added a can of freon. Still blows hot and auxillary fan still does not work. I was going to replace the relays for the a/c next.
