a/c is blowing hot air. Changed the clutch last week, worked fine until today which is one week later. What else could be the problem? Could it be the relay? Help!!

You changed the clutch... did you change the hub/bearing and the coil, too?
All these are sold separately, but should be replace together.

Yea everything but the compresser

Does the clutch cycle? The A/C switch light isn't blinking?

For Air Conditioning Operation:
When the blower switch is on, power goes from the HTR fuse to the HTR relay to the A/C fuse to the TERMINAL 2 of the A/C SW. If the A/C SW is turned on, at this time a signal is input into the engine control module. This activates the engine control module and Magnetic Clutch (M/G CLT) relay. So that current flows from the A/C fuse to M/G CLT relay to A/C magnetic clutch. Causing the compressor to operate.

It was the mag clutch relay under the hood changed it out a/c works fine now

Thanks for the help
