Need location of water temp switch ac (1 Viewer)

Narrowed my ac problem down to water temp switch but can't find it? Anyone know where it is?
Thanks for the help

The only purpose this serves is to cut off the compressor if engine Temps rise past 226 correct ? Okay to bypass this?

It also tells the ecu when you hit 131 degrees and allows the transmission to shift into overdrive. I don't think your truck will ever go into overdrive if you bypass it.

Overdrive works fine, just tested it. Thanks for the heads up

Don't know, never tried it. Give it a shot and report back. It would be interesting to know.

Thanks for volunteering.

Bypassed at the engine cool temp cut relay and everything is working well. Must have lost the water temp switch over the winter because ac worked fine last fall. Did do quite a few engine maintenance items so may have lost a ground on the switch

Can you tell me where this relay is located? My AC stopped working after the engine overheated.

Reviving an old one, those that had the water temp switch fail what were your symptoms? Mine blows cold when I'm sitting still and or when the ambient temp is cool. If it's hot and I'm doing highway speeds, I can hear something under the dash click and the compressor shuts off. Couple minutes later it will click on again and just cycle like this until I shut it off
