2003 Chevrolet Impala, Gauges and A/C Compressor Turn Off After 5-10 Miles of Driving

This 2003 Chevrolet Impala came in with the complaint that the dash gauges and a/c compressor turn off after 5-10 miles of driving.

2004 Chevrolet Impala, No Heat Driver’s Side, Code B0408

This 2004 Chevrolet Impala came in with the complaint that there was no heat on the driver’s side of the car.
