Hello from the valley of the sun stroke. It was only 113 today! I need some help replacing the drivers side temp door actuator. Thats right, its a 113 and I have refreshing hot air coming our of my driver side vents. On a positive side, I think I have sweated off 5 lbs this week. I have the floor panels off, I see the actuator, but it appears there is no easy access. I couldn't seem to find a thread outlining the steps to make this repair. Can anyone walk me through it. I think the writing is on the wall... I'm going to have to take the whole dash off.... someone tell me I'm wrong, please:p

FYI: I have tried all the reset tricks and took the truck into the Chevy dealer. They are indicating that when I changed out my battery, I ceated a fault in the actualator causing it to bind up. Same problem with the Mode Door Actuator, but with help from this website, I have successfully swapped out the the mode door actuator and restored air to my front vents! One down, one to go!

Thanks!!

:tiphat Welcome :tiphat . I can understand why you're working on it at night. It must have dropped down to a cool 100 by now.:D I can only give you encouragement right now. It's late but, I'm sure someone will jump in soon. I know I've seen posts on your problem, but can't remember the answer. Sorry. Good luck.

I feel your pain. Had this happen last winter with it blowing cold air instead of warm air on a cold day. After removing the lower dash as you have done, I was able to fit in a screwdriver and tap on the actuator. This broke it loose and has been working since but I don't trust it at all! :ugh:

Thanks WOOLUF1952 for the welcome. I'm loving this website. I'm still hunting through past posts for a solution. I plan to tackle this problem again on Friday. I may just try a temporary fix (i.e. Pull the wire connection and try to manually open the door). JnT4life, I wish I was soo lucky:) But... you never know, I'll see if I can give it a good rattle. I'm due for a lucky break.

well... I couldn't find any threads on the actual steps for replacing the drivers side temp door actuator. To me, it looks like I need to lift the dash up out of the way to get to it. Has anyone replaced this actuator before? I saw several post on the passenger side but not the driver side ~ Thanks

Driver side actuator

The steps listed to change and calibrate this device are great. I need to know where the driver side actuator is located. I know I am close because I have pulled the components from the center of the dash. I see the passenger's side actuater but not the driver side. Does anyone have a diagram. I am a banker by trade.... be easy.

Temp Door Actuator

I have a 2009 Saab 97x that always blows hot air out of the driver side vents. I went to the dealer, and they said that the Temp Door Actuator is bad and needs to be replaced. They said they would have to remove the dash to do this. I've read some other posts and I'm not sure the dash has to be removed to change the actuator. Anyone else experienced this?
