Hello! I have a 2004 Subaru Outback 4 cylinder. My AC is acting very strange, when I'm sitting still it blows cold air amazingly recycle or not. However, if I get on the interstate for about a mile it stops working and starts getting hotter. I know this is normally vise versa. Any ideas?

Does it go back to cold when you slow down or stop?

It may be the clutch plate slipping on the pulley. It's a fairly easy fix. You remove the clutch plate and there are shims behind it that you can take out. Majority of the ones I deal with I take out 2.

This is on an H6 but the H4 compressor is the same adjustment. And you can actually do this with the belt in place.

If it doesn't come back on cold when you slow down or idle and remains hot, there is a different relay that Subaru changed to for the AC compressor. Pick it up at Subaru parts dept. It's cheap.
