air conditioner clutch will not engage, connected 12v directly to the connector on the clutch and it did not engage. The repair person I use says the risk is high that the clutch failing contaminated the rest of the system and the compressor will lock or receiver/dryer will clog if they aren't replaced. I thought the clutch was isolated from the freon. Would you replace just a clutch? When the failure occurred the clutch would click on and off particularly at idle (cooled when it was on) and at that time I checked the pressure. The freon was full so I think it is still full with no leaks.
