well i recharged my ac the other day and now it blowing out 40* air in 100* weather!

one thing i noticed is it sounds like i have a mouse exercise wheel in the "black box" under my glovebox at all fan speeds, also if i shut the truck off with the ac on and restart it the fan wont blow air till you hit/kick the "black box" !

also replaced the check valve next to the intake manifold with one out of a universal vac line kit, i still have wacky vents!

is that black box the blower motor?
are they a pita to replace?
and should i get the check valve T from the dealership?

 

Take the black box apart and see if anything is in there with the blower. My dads durango blower motor was making noise and when we pulled it there were several leaves in there that the fan was rubbing against.

 

Yep. Blower motor is in there. It's either going to be something in there, as mentioned above, a failing blower motor, or, a failing resistor block. If you have to kick the box to get the fan going on any speed setting, probably time for a new blower motor.

 

quess i have to go through the old service manual and see how hard it is to yank out, and where to start

thanks for the replys

 

I pulled mine last weekend in just a couple hours, wasn't bad at all. If you remove it completely you'll have to evacuate and recharge your a/c though....

There's a really good DIY with pics on the heater core that will walk you through the removal.

I dont think you have to pull it out though man, I would just drop the blower motor and stick a shop vac up in the box or just sweep it with my hand.
