Focus AC compressor vibrating?

[jaykruger]

Every mornning when I start the car the car shakes, not super violent but enough to make panels, change, iPass rattle slightly and anoy me. after it warms up it goes away. I have already checked the motor mounts, trans mounts and such and they are all fine. The only thing that I can find vibrating in the engine bay is the compressor lines on the AC. The headers, general engine and transmission all are fine so it is pretty much just the compressor and lines that are vibrating. Now the AC works fine in the car so the compressor is doing the job there and it does go away about 1/4 of the way into work. So far I have ruled out

1. Belt
2. Bent or otherwise out of ballance pulley
3. Motor and trans mounts
4. Motor
5. Trans

Any thoughts?

Does the problem happen all the time or only with the a/c turned on? I have seen problems with a/c compressor clutches causing noise or vibration issues. I have also seen issues with the motor mounts, but it sounds like you have ruled that out.

All the time I have tried leaving the AC on in the morrning (damn cold earlier this week) and running the heater and running nothing. Same result each time.
