2001 Oldsmobile Aurora not cold

Joe, I got your answer a while ago, with the bad weather I will finally get a chance to check it. You say the blend door is by heater core, is that under dash or under hood? Will I be able to open it manually? Or is something in the temp. System need to be replaced to get it to work. Thanks Ken

Thanks, I hate to keep bothering you, but I need to find this problem, or I feel if I bring it somewhere I don't know I will get ripped off, And I cant afford that right now. Thanks again ken

Hi Joe,
worked for hours looking for the heater core and actuator, they really hid it. I see nothing mechanical I can even push, pull, or move, all is just electrical plugs a maze of them. This is a auto temp control system though. When I worked for ford 100 years ago when cars where simple, Almost! I left the business in 1975, and I do remember changing lots of ATC boxes on the 69 to 75 lincolns. At least they were visiible. Have you got any other thoughts? Not so easy now that I cant grab one from the parts dept, and plug it in. Cars have changed, and I'm glad I'm out of it.I changed a window rigulator today, and at least that was easier than they use to be. Any other suggestions I would appreciate, And of course I'll be happy to send addtl. Funds if you can get me through this. Thanks Ken

I tried that to, and couldn't find anything. This car seems very challeging no matter what I do. Never get the right parts, seems like Olds, thru something together on this model. I did call a dealer, and I don't know where your from, but here in NY, there not to people friendly. I just was told in a rush bring it in we can check it for $ 125 Thats' kinda why I'm here. I really that you for all your help. Ken. I'll wait to hear from you.

Joe, and you still believe that is the problem? Do you feel confident the blend doos are it? Thanks Ken anything else you think of let me know.

I ordered a chilton on line, and best I can tell, it gives me a general location. But as I check the cost on it, at about $104 to $120, it also says a left and right, Do you think I need both? Thanks Ken

No dual climate

I have the same problem on my 01 Olds Aurora 3.5. I did find the actuators by removing the panel under the steering wheel (in my case I only have the problem on the driver side, passenger side is cold - dual zone) and you should see the two actuators. Try changin the temp setting while the car is running and you should see the little wheel move.
My question is, if removal of a dashboard and replacing the blend door realisticly is something someone with technical skills (I'm an engineer) but not much practical experience with cars and no special tools can do? I'm trying to decide whether or not I should try to save the $4-600 my mechanic has predicted it will be in labor to remove the dashboard and change the blend door?

Thanks so much for that info. I have been told by 3 or 4 people the blend door is the problem.I was a mechanic in the late 60s to the mid 70s, for a Lincoln dealer, so I was thinking blend door myself.I had changed many, but they were easy to get to compared to now. Seems this car is very expensive to do anything to, and part are always special order or dealer item, even the radiator hose I blew a week ago, it was a dealer item. Would you believe? I had to adapt a flex hose to work for now and special order the right one. So now I just want to fix this oroblem and sell this car.I've had enough.I am getting a quote tomorrow for the a/c and see if that is it. Price will determine if I fix it or not. I went to trade it in yesterday but with 227,000 miles they offered me $200.00 max $300.00 and didn't even want to look how clean it was. I can get more in scrape metal, or sell it for parts. Thanks again for the input. Ken.

I was able to locate the heater blender motor. Under the driver side dash, remove the bottom black panel and the kick panel by the gas pedal. Look up towards the center of the console. You will see two similar driver motors. The bottom is the blend motor. The top controls where air is directed. Comes off easy with 2 screws. Remove, turn on car and run temp up and down. Motor should turn smooth. Also check post that motor drives. Will also turn smooth if OK. Oh, it is A LOT easier if you remove the driver's seat. Only take a minute and well worth the ease of access. Drive motor is less than $100 and whole job took me less than 1/2 hour.
