The A/C Clutch will not engage. What could the problem be?
A. There are several different reasons why the A/C compressor clutch does not engage when you turn the A/C system on. The most common problems is that you’re system is low on refrigerant which is preventing the cycling switch from engaging the compressor. That’s because it’s acting as a safety for the compressor. It is not recommended that this safety switch be bypassed as it could cause serious damage your system and vehicle. What is also becoming more common with the very wet weather we are having is the clutch mechanism becoming seized with corrosion and/or debris picked up when fording flooded roads. The nature of air conditioning is the compressor; to work well and receive optimum lubrication is usually mounted at the lowest point of the system, which means low down in the engine bay. Driving through floods can seriously damage your compressor.
