Has anyone else had the air door break in the heater box?
It looks like a bear to fix.
Anyone done it before? Short cuts or tips would be great.
thanks

 

do a search for blend door and can read all night long. Theres a great right up located on this forum on how to replace it. Fill in you signature with your truck info, so we will know what year and model you are talking about and we can help you better!

Thanks goes to ratlratl for the AWESOME write up. If you decide to do the job yourself, PM me, I've a got a brand new one in the garage I bought and never installed, then went and traded my '06 in for an '08

Thanks to you and Jeff for posting this info again!!

My mode door is broken and I'm facing the hassle of fixing it too. What a pain!

 

www.heatertreater.net is if this helps any.

 

Well to piggy back on this one...

Mine quit working right today, but not sure what the culprit is (assuming it's most likely to be blend or recirc door)... I can move where the air goes, ie, defrost, vents, floor, but when on vents, the passenger side blows cold and the drivers side is warm, on defrost its cold air out the top and bottom both sides of the truck...

I have the Dual climate controls if that makes a difference...

I've already read until my eyes hurt and can't find the same situation I am having...

thanks for any help! I need to use the truck Friday for a long trip!

 

First post, no signiture.
My 2006 just went and there are no parts left for that Model Year. Being that mine failed during the warranty period, they upgraded me to a 2008 heater box, wiring, evaporator, and control head. Crossing my fingers it lasts this time.

 

well, that's not encouraging!

 

I am NEVER going to move that controal switch.

 

Someone on this great site once posted to only move ANY climate control **** after setting the fan speed to the lowest and waiting 10 secs for the air speed to drop. That way the doors aren't fighting the resistance and breaking.
I do this religiously!
Also on cold mornings, under 20F, I wait for the motor to warm.
I do this after moving the hot/cold control one morning without the fan on and hearing a snap and something fall down behind the dash. I now assume the plastic was brittle.

PITA I know............

 

From what I understand, the computer that runs the HVAC occasionally runs the flap motors until they stall, to calibrate for their range of motion.

There was a post a while back about a company that makes metal replacements, and has a repair procedure that doesn't require removing the housing (by cutting windows in the housing).

 

www.heatertreater.net

 

My recirc door is broken, for the second time, and I'm considering the metal replacement door(s), but I've been looking for feedback on here as to the fit, ease of replacement and quality of heatertreater's metal parts.

So far I haven't gotten a response . . . has anyone tried them??
