2001 chevy silverado 6L
Dear MW: I have a 2001 Chevy Silverado A/C problem. The
compressor cycles on and off very fast. It does blow cold but not long
enough to cool the cab, inside temp is 120 a/c cools down to 80. System
appears to be full. Can you Help?
MW:
As long as you are SURE that the freon charge is correct (best way to check is to
evacuate, see how much came out, and re-charge with proper amount)
then 1 thing to look for is a problem with the low pressure switch. They have been
known to be faulty and cause the cpmressor to cycle on and off. The low pressure
switch screws into the acumulator, and has a 2-wire connector. The accumulator is
the aluminum cylinder with 2 lines attached to it. It is near the firewall, on the pass.
side.
A light tap on the sensor while compressor is on, usually will turn off compressor and
indicate switch needs to be replaced.
