probably the pushbutton unit. i would check the in-cabin temp sensor first, but i think if its inop it would blow heat all the time if not in the min setting. testing is easy with an ohmeter
85 300SD not blowing once you move thermo past min
Hey All,
I'm having an issue with my 85 300sd where the blower shuts off if you move the temp control past min. It will blow if it is on min but nothing past that. Defroster won't blow either. I can feel heat coming out. I was thinking maybe monoclave valve but wanted to see if anyone had any other ideas. Checked and replaced the fuses. I can get it to come on randomly once in a while but Sunday night it stopped working again. Any ideas are appreciated.
Thanks
