I have a Honda CRV 2002 EX all wheel drive
Years ago the AC Compressor would not turn off I could not find the fix
Eventually It died
It's about 5 years later
I had the complete system replace including hoses evaporator, everything
The AC works great but the compressor won't turn off
If you turn the inside controls off, the idle drops and engine wants to die, and sometimes does
but the compressor clutch will not disengage
Relay works when signal is sent and opens when you take signal away from relay coil
I don't know the answer
Can someone please help me

Not an AC specialist but I'd take it to someone who knows AC.
If you screw up the compressor it could cost you big bucks.
Someone will probably check it for less than $100 including a Honda shop.
Better get with it before it burns up.
What do I know? I'm just a guy on a computer.

Two possibilities here:
Either the clutch is mechanically locked (frozen) to the compressor shaft or the relay is stuck closed, possibly both. Visually check for clearance between the clutch driving and driven plates with the engine off
When you say "Relay works when signal is sent and opens when you take signal away from relay coil" is the load side of the relay indeed dropping voltage to the clutch? Best to check for voltage at the clutch lead when the relay de-energizes, or seems like it is doing so. If there is no voltage at that lead then Martians may be inducing some sort of stray voltage to the clutch... (I'm sorry, yes I can be a wise*&%) :Eyes:

Unplug the connector going to the compressor see if it disengages. As what kalanikaau said you might have a bad relay that is stuck & sending power to the clutch. As what fubarnow mentioned have this one rectified ASAP as this will burn your compressor quickly & will cost you dearly.
