Climate controls

Dieselpowerking · Feb 1, 2019

So my climate controls wont switch from defrost and the temp wont switch from heat. Am I looking at replacing the switch? I have vacuum at one of the lines that goes into the cab. 4x4 doesnt work but I have vacuum at the lines when it's in 4x4 and 4x2.

Do you have enough vacume it could be that you have vacume but not enough

I didn't put a gauge on but seems like very little at the 4wd stuff and good amount at the one st the fire wall

I would check for vacume leaks if your leaking you could have enough vacume for some accessories but not the ones that use a lot

Anywhere else I can check besides under the hood? Been in the cab a little bit havent found any besides not pulling the dash yet

You should have 1 vac Line entering the cab to the selector valve then at the valve it branches off to the areas needing vacume and it should be accessable without removing the dash
