2000+ Blower Motor and Evap cleaning?

[mikeluscher159]

Hello.

I've finished pulling my interior and drying it out

Cabin filter was disgusting, and interior has general funk that I'm working on (carpet mold, headliner mold)

Any pointers on blower motor removal and reasonable access to the evaporator so I can hit it with coil cleaner and to rinse it?

I've also got to replace both temperature blend doors (Dual Zone Auto Climate)
Am I pulling the dash?

Also, for no understandable reason, every time I start the HVAC, the A/C compresser comes on, but if I cycle the button on, then off again, it turns off.

I don't know what lead up to this problem but I am guessing a clogged a/c evaporator drain if it has flooded your carpet. Make sure you check and unclog it if necessary or your car may flood again.

These instructions look like they apply to my 1992 Bonneville so I am not sure yours is the same. I did find this posted: http://www.pontiacbonnevilleclub.com/fo ... c2432.html
The only thing I wouldn't do with these instructions is personally I would never use carb cleaner or any flammable solvent to do the actual cleaning unless I had the evaporator out of the car. I have used simple green with great results. I would not use any flammable fluid in any HVAC due to the sparks made by the various motors/sparks.

No. They don't correlate. Car sat for a year with wet carpet from the sunroof and doors, and I wanna try to get the smell out of the HVAC system.

First warm day in a while, I've actually confirmed the A/C works. Drain seems to be functional.

Make sure the drains for the sunroof are open, the drain tubes are a three piece design and where they connect together come apart. I used a longer piece of string from my gas trimmer. The front two exit the car in the front wheel well behind the tire behind the plastic cover so you wont see it unless you remove the plastic cover. Not sure about the rear.

As for the blend doors, do you have to replace the doors or the door actuators? The actuators can be replaced without dash removal. I replaced the drivers side one, pain in the butt but do able.

My temp control on both sides is lackadaisical and slow, and unreliable
I do have good Heat and A/C..... sometimes, when the doors let me

I've got
B0269 Air Inlet Door Range Error
B0279 Air Mix Door #2 Range Error

If in auto mode, the HVAC will run the AC at all times when outside temp is above 40 degrees to dehydrate the air.

Remove the passenger side hush panel. I believe it is two 7MM bolts and a christmas tree style fastener. The blower itself is held in with (I believe) three 10MM bolts and then its electrical connector. It will involve some wiggling to remove. If you're a big guy, removing the passenger seat would surely be a help.
