La gator Posted October 21, 2017 Share Posted October 21, 2017 system seem to be fine but not competing with the heat. very light pressure from fan/blower. Quote Link to comment Share on other sites More sharing options...
MHfred Posted October 21, 2017 Share Posted October 21, 2017 (edited) I would verify no hoses have come off assuming your truck has them. After that I would verify the heater core and A/C cores are not plugged. Your fan probably blows through them. EDIT: I do not mean coolant hoses or A/C hoses but ventilation air hoses.

Dieseltech740 Posted January 27, 2018 Share Posted January 27, 2018 (edited) I work on dump trucks that are mostly dirt haulers and I can’t tell you how many times I’ve worked on one and the exaporator was full of dirt and when the ac kicks on it turns to mud. Which onviously restricts the flow a ton. Can’t tell the drivers enough to keep their ac on recirculate Edited January 27, 2018 by Dieseltech740 Quote Link to comment Share on other sites More sharing options...
