Lexus GX 460 2013

AC recently stopped working. Found out it was a broken pressure relay switch.

Now having the current problems

- Engine start stop button not working. Have to touch fob to button. Replaced battery in fob still not working.

- Drivers door not locking or unlocking to fob or door button. Every other door locks and unlocks. Have to manually lock it from inside.

- PWR VOL **** doesn't work 80% of the time. Turning up or down doesn't work. Works from steering wheel.

 

vol has some haptic type setup. if too hot it can slip or not stay engaged.
for fob, check to see that wireless access isnt disabled. some disable WA to prevent relay attacks. disables will also require touching to the button.

 

Do you have another FOB to test with?

You may have a failing door lock actuator
