ok help me please....My A.C works PERFECT while driving. The only problem is when i come to a stop and sit for a little bit, the compressor shuts off and it starts to blow hot air.
Now here is what i know. I know there is a shut off when the compressor reaches a certain temp. The condensor fan is not turning on at all but it does work because i hooked it staright to the battery to test that.
Does anyone know what this might be? I brought it to the mechanic and rescheduled an appointment for the 25th. I have a baby due this week and really cant afford to fix it right now.
Is your auxilary fan working with AC engaged and car at idle, if not, then I would suspect the temperature switch. Have you tried to jumper that and see if the aux fan works? The issue may be lack of air flow at idle across the condensor and tet aux fan not working at idle could be the culprit.

The fan does work when bypassed so it is not the fan. Could be the resistor. Where is the resistor and how do you check it?
You say the fan runs when jumpered, are you jumpering straight to the fan motor or to the fan temperature switch? If to the fan motor then you have not tested the temp switch. The resistor should be in front of the fan and it is a small, plug in part.
