AC cycling switch

[andy1]

I had my AC recharged and it worked great but the following day I had nothing but hot air. I read somewhere about a cycling switch may be the problem or maybe the clutch. Where is the switch located and is it an expensive part ?

There were no leaks in the system

The clutch pressure cycling switch is located on the top of the accumulator. The accumulator is the black cylinder located below the space between the battery and the radiator.

Chances are, you do have a leak and have lost your freon.

The cycling switch is under $20 bucks at PartsAmerica and can be replaced without discharging the refrigerant.

Without a set of guages ($60 bucks at PartsAmerica for a 134 set), you'd only be guessing at what the problem is.

If you have an ATX, the accumulator is located near the firewall on the passenger side. The cycling swicth can be bought at any auto parts store for about $12.

Are you sure that switch can be replaced without discharging the Freon? I thought it came into direct contact with the Freon? Or is there a diaphram in the top of the reciever to isolate it?

There is a diaphram to isolate it. I've changed numerous switches over the years. Simply unscrew the old one, screw the new one in, and reconnect the harness.

There is a Schraeder valve under the switch.
