Ok I'll try to make this as short and sweet as possible. 2006 1500 and i know i have a problem with the blend door(s) that change the vents my heater/AC blow out of. If i set my **** to the dash vents, it blows from the dash vents. if i set it to my defrost vents, it blows from the defrost vents. But if i set it to the floor, it blows out of the defrost vents. Basically no matter what position, i can't get any air outta the floor vents.

I have read a few other posts on other sites and have gotten a few different causes (at least in reference to which of the 3, i believe, blend doors might be the cause). I have also heard that this is a common problem for newer vehicles with mainly plastic made blend door motors (and even more common for the 02-08 Rams' blend door design).

Anyone able to point me to the right direction as to which blend door(s) could be to blame? Two of them shouldn't be a problem getting to (minus having to tear the dash apart) however i've read that the third, somewhere closer to the drivers side, is near impossible to access without cutting out a welded in piece of stamped metal bracing. If it IS that one maybe someone out there has a trick or something to gain access to that blend door. ???

 

is that under warranty?

 

Sounds like broken defroster door???? Here is a link to an 2003 TSB

I don't think so. Either way, I don't think my truck is under any more warranties. Its a 2006.

 

Try these guys. Good Luck.

Hey thanks for posting that link!!!. I will be looking at it should I ever need anymore HVAC repairs.

 

I posted this a while ago but I wanted to update. I had multiple blend doors broken. I started to tear the dash apart and just did not have the time to finish. I opted for the dealer to fix to the tune of $700. It's been a year-ish now and no issues thankfully.

 

Thanks for the update.
