2003 Chevrolet Silverado A/C Problem
I have a 2003 Chevrolet Silverado, 150k miles, & the A/C is starting to work sporadically.
Going down the road & blowing cold air & then all of a sudden, warm air, or vice versa. A/C working fine, stop somewhere get back in & start up, A/C blowing warm air, or vice versa.
When A/C is acting up, cannot hear or see the A/C clutch engage.
A/C is full of refrigerant, fuses are good, replaced relay/switch (or whatever it is called) under the hood in fuse panel.
Anyone of have a similar problem?
Thanks

You said its full of refrigerant, how much is in it?Have you checked your high & low side pressures with it running? Sounds like it's either low on Freon or the high side pressure is building up and shutting off the compressor.
