2006 Honda CR-V, the ac clutch clutch is not engaging. I have checked the relay in the fuse box and it is good. Haven't checked for low refrigerant pressure yet. Can the clutch be replaced or might I need a whole new compressor. The current AC system was completely replaced two years ago

 

the number 1 cause of ac problems is a leak, check for power going to the clutch connector when the ac is on .... only if power is going to the clutch connector can you then lead to possibly the coil being bad

the actual clutch itself rarely goes bad, the air gap will get too large to allow for the clutch to close or the coil will stop working, or the bearing in the clutch assembly will go bad and seize up

 

Thanks for the response. I added refrigerant this weekend and the compressor kicked on. I'll watch the pressure over the next couple of weeks and
see how much of a leak it has.

 

This may help :

 

This happens to be the dumbest thing I have ever seen.

 

Why is that?
I didn't watch the full video but I have seen a few people mention successfully doing some kind of mod to a worn Honda AC clutch to make it stop slipping.
Seems to be an adjustment or shim somewhere to get the friction plate engaging properly again.

 

70383roadrunner, It seems as if the OP has resolved, or at least Dx'd his problem to be a low refrigerant issue. That said, this "hack" is not that far out of line. Esp if you've already resigned yourself to replacing the clutch any way. I have seen this and done this myself successfully several times before. Not by filing or grinding, but by removing shims. Many vehicles have very thin shims between the magnet coil and the clutch plate, one or more of which can be removed to decrease the air gap, My 07 Civic has these and I removed one (after trying the easy stuff, and also checking pressures). It resolved the issue (intermittent AC compressor coming on). You can also Dx this to to be an air gap issue by gaining access to the compressor clutch (however that may be for a specific vehicle), and witht he AC controls in the car on and engine running CAREFULLY use a wooden dowel and something to tap it with, to just tap the compressor clutch. If it is an air gap issue, the light tap on the clutch will cause the compressor to engage for one cycle. It may or may not do more cycles. Either way you will now know the issue.

Best...
