E5Farmer Posted February 14, 2022 Share Posted February 14, 2022 (edited) 12 CXU613. Problem, cannot control temperature of air coming out of vents in cab(always hot). Also cannot control the mode (vent, defrost, feet,etc…) I can control the fan speed itself. I have replaced the control unit itself, I put in a new actuator in the dash, neither have fixed it. The relay in fuse panel on the dash has power. I am not familiar with wiring of these trucks but I’m assuming if it was a fuse I’d lose all control including fan speed, Not just temp and mode. Any and all suggestions appreciated! thank you Edited February 14, 2022 by E5Farmer Quote Link to comment https://www.bigmacktrucks.com/topic/69222-no-cab-temp-or-mode-control/ Share on other sites More sharing options...
