the clutch wasn't eng? My 2003 corolla A/C has been working intermittently the past few days. I determined that the clutch wasn't engaging. I played with the MG CLT relay, and it kicked in, but I'm not sure if that was just dumb luck. What are some of the different things that can prevent the relay from engaging the clutch? I put some refridgerant in the other day, but I still haven't taken any pressure readings.(I'm not sure where to take them, and what pressure is normal.) When the A/C is engaged it's nice and cold. I just would like to try and isolate the problem a little more before spending too much money chasing the problem around. A new relay should only be $60, but I'm not 100% sure that's it.

I'm not sure how to jump the relay, so if someone could explain it might help.

Any suggestions would be greatly appreciated.

Having put some refrigerant in, you need to take it to an auto A/C professional for service anyway. It is very likely it is overcharged now and the compressor will be damaged if you run it that way. The A/C tech can find the problem pretty quickly and save you $800 - $1000 for a compressor replacement besides.

if the system doesnt have a certain pressure in it at a minimum then it will not allow the compressor clutch to engage because there is a pressure switch in the system. a salvage yard compressor is not expensive, even a remanufactured one is less than 200 bucks
