Contour Enthusiasts Group Archives Forums General Troubleshooting A/C only blows hot air

Well, looks like I got lucky. Brought it to the dealer to diagnose. They recharged and added some dye. A/C started working with the recharge, and no leaks found. We'll see if the issue crops up again. Might just be the fact that it hadn't been recharged since it was built 9 years ago

Well, we're back to warm air. Returned it to the dealer, and they claim it's leaking from both the compressor and accumulator. Looking at fordpartsonline, a compressor is around $252 and they don't list an accumulator. They list a drier (for about $80). Are those terms used interchangeably now?

My Mystique's a/c is doing the same thing. Currently, my theory is the compressor o-rings were bad and the clamp bolt was not sealed properly. I will be testing it soon... The accumulator is sometimes called a filter/drier. That thing can rust out, you might see oil residue on the foam liner around it. At least up here in NY, there is a little time to fix it before I need it..

My cycling switch failed a few years back - it short cycled. When I replaced it the compressor ran 3 times as much and the system got cooler faster. A few months later the relay that drives the compressor clutch died. I could hear the system try to come on but the compressor failed to engage.
