Depends on the make and model of the vehicle. On newer cars check the power distribution box where the relays are located.
The 1992 Chevrolet Suburban air conditioner compressor relay switch can be found in the fuse box. The air conditioning compressor relay switch will be labeled as such.
My UK data is showing the Air compressor clutch relay location is fitted to the left hand inner wing (when viewed from the the driving seat).
Fuse? Relay? Switch?
That other relay should be the AC compressor relay.
AC relay is inside fuse-box on driver-side inner fender. Relay diagram is inside cover.

The AC compressor relay is located under the hood, on the firewall, passenger side.
check the cycling switch.

First you need to check the a/c relay switch located in the fuse box in the engine compartment, try switching it with the cooling fan relay,if this does not work, then you probably have a leak in the system and your a/c pressure switch is not allowing the a/c clutch to engage.
Under the hood in the aux relay box number 1, it will be marked C1008 and its the larger of the two relays on the left side of the box........
the compressor relay is in the underhood fuseblock drivers side of the engine compartment.
