Hi, the a/c on my 2000 chevy blazer is not working properly. It usually does not come on when I crank it up and sometimes will come on after I get going but shuts back off and on throughout the trip. I have replaced the clutch and it spins sometimes, what else could it be?
where would the relays for the a/c be?
Do you
have the same problem?

Have you had the freon checked? Low freon will cause the clutch to cycle in and out every few seconds or so.

Freon is good. It is completely charged. Do you know where the relay is and if ti could possibly be that.

Not exactly sure which one it is, but the relay is in the underhood power distribution box. There should be a diagram of the fuse and relay location on the inside top. You may also want to check the Cycling Switch. It is usually located on the Accumulator but can be located in the line somewere......

Here is what the Switch looks like....
