SLEDOG Posted November 19, 2022 Share Posted November 19, 2022 Well I’ve had some good luck fixing my 07 granite on this site so here I go again… Blower works great but not much at defroster vents when called for. im taking console apart now and was wondering if there is a flapper or something that I need to check and how do I get to it…. Thanks Sledog Quote Link to comment https://www.bigmacktrucks.com/topic/70724-granite-not-directing-air-into-defroster-vents/ Share on other sites More sharing options...
Onyx610 Posted November 20, 2022 Share Posted November 20, 2022 Mode box is pry bad. It’s been a while so I’ll have to look In the book tomorrow for you.

Joey Mack Posted November 21, 2022 Share Posted November 21, 2022 The mode boxes in those trucks were known for the gears stripping and causing the issue you have.. so basically, you need to suck down the A/C, pinch off the 2 heater hoses at the firewall to remove them, and remove the A/C lines there as well, pull the floor pan around the shifter out, so when you remove the HVAC unit, you can tip it out. you may need to put the stick in 5th gear for extra room. Then you do the repair on the bench. I dont have the bulletin, but I bet someone will post it for you.. Good luck, Jojo Quote Link to comment https://www.bigmacktrucks.com/topic/70724-granite-not-directing-air-into-defroster-vents/#findComment-515595 Share on other sites More sharing options...

Joey Mack Posted November 21, 2022 Share Posted November 21, 2022 Yeah Buddy,,, you dodged a bullet there.. Glad you pulled the cover off before digging in to sucking the A/C and coolant lines and such.. was it the arm and lever right in front when you pulled the cover?

SLEDOG Posted November 22, 2022 Author Share Posted November 22, 2022 Ya Joey it was right behind the control board on the right hand side. It doesn’t look like it popped off by itself…. Probably was swapped with her sister truck and never got hooked back up…. Pretty sure it’s been like that since I’ve owned the truck…… Sledog Quote Link to comment https://www.bigmacktrucks.com/topic/70724-granite-not-directing-air-into-defroster-vents/#findComment-515707 Share on other sites More sharing options...
