Issue:
No power to the Heating and A/C dial in the cab. It’s the one that turns the blower on and then up to level 4.

Completed:
Replaced the small black relays at the front/top of engine.
Made sure all the belts were good.
Checked all the fuses under steering column at the floor.
Removed top to try locating any other fuses... none seen

I don’t have a wiring diagram and can’t seem to locate one online.

Can anyone help...?

Thank you in advance!

Fixed it!!!

Had to remove the top of the cab. Once up there, I replaced the black box/controller that sits just to the front of the HVAC dials. It’s like a 16 pin connector. After further inspection, the old connector had a burn spot on the electrical board. Couple hundred buck later and some labor, viola I have HVAC!!!

Glad you got it fixed. I'm not experienced in HVAC stuff, but sounds like yours was more electrical. Surprised you got the part so soon. Everything around here is out of stock. (including hydraulic oil)
