Pulled dash and replaced blend doors but not air!

[Jbremount]

I just finished pulling the dash and replacing the broken doors in my HVAC box. After putting everything back together, the AC blower motor will not come on! The new door work fine. What could cause the AC blower motor to not work? Did I miss plugging in a wire or something?

Might be the resistor for blower, it has a plug, also the blower. Resistor is mounted in the A/C housing just behind the glove box. bg

Fixed it! It was the blower motor resister. Darn thing was working before the dash removal, but it's not working now. I stuck in another one and the AC fan blower is working like a champ now.

That is interesting as when the resistor fails you should have high blower.

My blend doors went to "S" 6 or so years ago I guess about three years old so in 2008 or 09 I forget because it's been so long now. I have yet to install the HeaterTreater metal doors and just been living with it. Every summer I say I'm going to tear into it but never get to it mainly because, I just haven't found a really good video or ACCURATE step by step instructions to remove everything needed and reinstall so it all goes back perfectly without a hitch and no noises. "Squeaks" which I have heard others experienced via the dealership R&R. It would be awesome if anyone out there reading this has info on the R&R.

Go to the Advanced Search at right hand top corner and type in "AC evaporator removal", there are some good writeups with pictures there. bg

Looked at the first one from Shroder but no pics to see. Wonder what happened.

It's not that bad to do. If you are worried about forgetting anything while going back together just take lots of pics while coming apart. I have taken pictures just to show the owner how many parts and fasteners are involved

So far,
I haven't found a really good video one without all they shakiness or one comprehensive start to finish. I'll keep looking unless someone references it. I'm not too concerned about being able to do it, I'm very mechanically inclined, just want really clear instructions w/o all the acronyms people are so fond of using. Lol
