BigFrizDog Posted June 10, 2015 Share Posted June 10, 2015 05 Granite Tri axle MP7 Allison AutoThe temp inside my cab down by my calves gets up to 120° !!! It seems worse when the windows are down. I guess it's pulling in air from the engine bay, I don't see any visible openings though. There isn't any insulation under the cab either, don't know if there is supposed to be or not. A/C blows cool, pretty sure it has a leak somewhere just haven't found any oil stains. I also think the hoses in the dash might not be connected properly, blower motor blows loud/high but it feels like its on medium coming out of the vents. Any help /suggestions!?!Thanks, Chad Quote Link to comment https://www.bigmacktrucks.com/topic/40403-inside-cab-temp-hot/ Share on other sites More sharing options...

j_martell Posted June 10, 2015 Share Posted June 10, 2015 check the cabin filter (inside the "kick panel" on the passenger side i think) if not running on recirc.

Phase 1 Posted June 10, 2015 Share Posted June 10, 2015 Possibly there is hot air coming from the heater when it should not be. Feel in front of the heater vents with the fan on and engine temp warm. The valve may not be closing. Quote Link to comment https://www.bigmacktrucks.com/topic/40403-inside-cab-temp-hot/#findComment-292815 Share on other sites More sharing options...
Timmyb Posted June 11, 2015 Share Posted June 11, 2015 Is there a rubber boot around the steering shaft hole? I know on my kw they split and hot air will come thru. Or could be gear stick boot... Check in between the folds. My air con fans brushes wore out. New fan and she was blowing my air like a shampoo commercial! I only hope it's something that simple. Best of luck. Tim.
