Chrysler PT Cruiser Car AC Clutch Cycling Switch Replacement at your home or office.

What is the AC Clutch Cycling Switch all about?

You may think that the compressor or the compressor clutch are the most likely components to fail on a car’s air conditioning system, and they are high-wear items. However, the AC clutch cycling switch is actually the most common part to fail on many vehicles. The switch has a simple job, but it must engage and disengage every time the compressor cycles. This creates significant wear and tear, and leads to eventual failure.

Really, the name says it all when it comes to what this switch does. The AC cycling switch opens when the low side AC system pressure drops too low to allow pressure from the high side to equalize the system and keep refrigerant flowing through the entire air conditioner. The most common problem with the switch is with the contacts – wear and burning render them inoperable. If this happens, the entire switch must be replaced.
