AC would blow cold for 15 minutes, the blow warm air and Check AC message would appear. Got home let her sit for 30 mins and started her up AC works fine, 15 mins later AC blowing warm. Got back home and rear AC also blowing warm. DX: AC clutch relay was bad ~ identified as MG Relay. It's located in the fuse and relay pod, drivers side, engine bay, right at the top on the right. I swapped the FR Fog relay with MG Relay and got my AC back. Ordered the following https://www.rockauto.com/en/moreinfo...=1434549&jsn=9.

Fuses are straight forward as to which you can swap out. I could not identify the compatibility between the relays. They fit the same so took a chance. Anybody know?

 

There are about 7+ different part numbers for the relays and I can't tell which ones are for the A/C clutch and fog lights. All I can suggest is look for a manufacturer's part number on them and see if they're the same.

It's labeled on the relay cover as "M/C" for magnetic clutch.

Highly recommended replacing the relay if the vehicle is 9+ yrs old.
