Thank you. I didn't know what this switch was. A squirrel chewed through the cable a few days ago. There are no issue lights on in the car and testing it now, we can tell that the A/C doesn't work. :| but with this video we now know what the problem is! Thanks

Could you start doing “how to test” to make sure it working before someone attempts to do this?

[@rodneyrhonemus3197]

How do I know if this is my problem?

[@macknumber9]

I want to know this too

[@melissaiodice1752]

Me three. My ac comes right out of the bottom of engine on compressor as soon as Im filling it and a little knob like thing broke off it

I would place a multimeter on the leads and check for continuity when the car is on, and AC is commanded to "ON", no continuity means the pressure switch is not actuating when sensing the high pressure in the line. Make sure the high pressure side is not the problem, when there is a leak the pressure will never get high enough for the switch to activate and activate the AC compressor clutch.
