2000 Chevy ac problem

[heavy_chevy_07]

I have a ac problem. I have no power at dryer. Anybody know what it might be

[screaminchicken]

If by no power you mean no pressure, you could have a clogged orifice tube. What do your low and high side pressures look like?

What about your other sensor? Do you have power at it? One thing to check..... Take a jumper wire from hot side of batt. Hook on to compressor to make it kick in manually, have gauges hooked up and make sure pressures are normal.....if so check your other sensors some systems have two some three. The sensors are in a series type circuit so If ones bad it will still have power but power won't come out the other side to the next sensor. HOPE this is correct or helpful

I have an ac problem myself. Except its just a snapped belt from the compressor to crank pulley. Getting ready to tackle that issue.

sounds like a bad compressor, usually u can replaced the compressor and orfice tube and flush the lines, then you will be good to go

Or it could be the belt was way past due... guess we will see if the new belt breaks. As far as I know the belts could of been the same as when it left from factory. Im past 185xxx miles. Got it at right at 100k. I never had to replace the belts.

Belts are common to break, way to small in my opinion.

Ended up being my compressor is seizned up. Made a horrible noise then seized and started burning the new belt. Go figure it breaks right when the temps are rising. But what I thought the water pump was going out was the compressor making the growling bearing noise.

That sucks, changed many belts thru the years and 9 out of 10 times fixed the problem. Guess you were number 10, sorry about the luck!
