AC Low Pressure Cut Off Switch Location

[DrewA]

I swear but can't fine it in the forum or manual. Just dense I guess.

Where is the AC low pressure cut off switch located?

And shorting between the wires does it engauge or disenguage the compressor clutch with ignition on but engine not running?

Thanks. Sorry about the bad searching.

Its on one of the ac lines up front.

About all the switch and the fan control unit do is stop the signal from getting to the relay that turns on the compressor clutch. Shorting the switch will turn on the compressor clutch and applying power could damage the fan control unit.

Here is the info on the operation of the switch.

I'll have to look again. Must have missed it.

I have absolutely no pressure in the AC system. Pushing in both blue (low) and red (high) pressure valves gives no pressure.

Time to find the leak. My system was converted to 134A a long time ago. Hopefully the dyed prodct can fine it and it is not in the evaporator under the dash.



Thanks,
