Sequoia AC Compressor Failure

A/C issue with my 2007 Toyota Sequoia (gasoline engine). Compressor seems shut off completely, no cooling. Error memory shows undervoltage. Belt tensioner and pressure switch look fine. Any thoughts?

I had a similar problem with my 2012 Jeep Grand Cherokee. Sounds familiar. Start by checking the AC relay; might be a simple fix.

Thanks! Where is the AC relay located in the Sequoia, and how can I test it before replacing?

I'm not familiar with the exact location on the Sequoia. My mechanic found it and confirmed the fault. I'd recommend taking it to a workshop.

Mechanic checked the A/C system. Faulty AC relay and wiring issues causing undervoltage. Total repair: 240€. Thanks for the help!
