A/C Compressor Cycles Once

I can start my car and the A/C fires up (ice cold) but after about 5-8 minutes, the compressor cycles off and never comes backe on. I can shut the car off and wait for a few minutes. Then it will come back. It just refuses to cycle back on.

This could be a slipping belt. There is a sensor on the compressor that senses that the belt is slipping and shuts it down. The only way to get it to reengage is to shut off the engine and restart.

The other thing could be the automatic climate control temp sensor. There is a fan that is on any time the ignition on. This fan draws cabin air over the temp sensor.

Ensure that the fan is turning any time the ignition is on.

Good luck,

Sometimes the sensor that senses belt slip fails & you get to buy a new compressor (not sure there is a fix for that).

The funny thing is it quits at the same intersection every day. I get about 4 miles from work and then kaput...
