Can you pull it out from the cowl opening?
>fan doesn't move
Connector not making contact? Some have contacts that burn.
Or the blower motor brushes have stuck in their channel where they slide. As they wear they don't move forward and lose contact.
Try tapping up on the blower motor with a vibration from your shoe or fist while the key and controls are both turned ON. See if it makes contact and catches. That would tell you everything else is working right.
#140 of 278 air conditioning water leak
Jul 22, 2010 (8:56 am)
I have a water leak in my 2005 Buick Lesabre. It happens when using the air conditioning. The leak appears to be clear clean water. It's coming from under the dash on the passenger side. The dripping is approximately three inches from the floor board hump. The amount of water is enough to saturate the carpet on the passenger side. I suspect it is a problem with the drain from the condensation removal of the cars air conditioning.
Any help with thoughts about this problem would be greatly appreciated.
Is the drain for the condensation under the dash on this vehicle?

I apologize that your vehicle has a concern. Have you had anyone look at the vehicle to diagnose the concern? Thank you,

If you mean have I taken it to a dealership for them to diagnose the problem...no.
I know how the basics work. It is most likely a broken piece of plastic, a misplaced, worn, split, etc drain hose. Most likely it will be something similar.
I just don't know the specifics of what I will find when I remove the uderpanel of the dash and get started on the repairs.
What I did do was pull the car into the gagage, disconnected the battery, mopped up most of the water, opened all the car doors, put a large fan blowing air into the car at the wet spot. I left it there all night...it is now dry and no spots in the carpet.
So, that is where I'm at on this problem. I was hoping someone had words of wisdom for me on this site with this situation.
Thank you for your concerns,

The drain is below the passenger side of the firewall. I believe it's a tube with a squared end. Probably the tube is clogged with some kind of goop. Push some kind of soft wire or something up into it and the water held back in the AC drain pan will probably come gushing out.
Dirt, pollen, mold, mildew, leaf particles, etc., can get into that area and form a muck that blocks the drain.
If you can park your car in some way to leave room underneath to crawl under from the side, you should see the rubber drain. I cannot see mine from the top of the engine compartment. Do not lift the car with the scissors jack for changing cars and get under. It is dangerous to do so. Jackstands are a must for solid support.

Thanks for responding. Great minds think alike!
What I have done so far...removed the dust shield from under the passenger side of the dash. Laid on the floor board until I slightly cracked several ribs I carefully observed under the dash and finally came up with two spots which had a water droplet suspended from them. I touched each with a corner of a paper shop towel to wick the droplet off and then observed additional droplets forming. Repeating this often, I figured I wasn't getting the proper draining of the AC water.
The plastic parts under the dash are many and packed in a close space.
My time was limited so, I had to quit for a time....which was a good thing. I finally came up with the same idea which you provided for me.
Again my time was limited. I have not jacked up the car and put it on stands yet. That is what I intend to do and then see if the drain is blocked. It may well be that is the problem.
I'll keep you informed if you would like, as I progress.

I've got the car jacked up and placed jack stands under it. Crawling under the car, I haven't found a drain line yet for the A.C.
From inside the car, under the passenger side of the dash...a drain line runs down and goes under the carpet and is angled as if it stays under the carpet and going toward the rear of the floor panel on the passenger side.
I haven't figured out how to loosen the trim so I can raise the carpet up to trace it better, but I took out the back seat and lifted the carpet up on the passenger side of the back seat floorboard...It's wet...real wet. Could the drain hose possibly run to the rear seating area and come out there?
Any words of advise are always welcomed.
Must go crawl under the car and see if I can figure this out.

I got under mine and left it running for a while to see where the drip comes down.
Behind the right front wheel look across and up under the car. There's a large cross beam. There is a 1.25 inch round bar about 2 inches behind it. I think that's the sway bar. The drip comes down just behind the big square crossbeam at about the point where the sway bar comes downward and bends to go horizontally across. I didn't try, but I suspect a long arm can reach upward to the area where the tube should be hanging. It will have some kind of system designed so it's not open except when water's weight is forcing water out.

Hey! Hey! imidazol97,
I really appreciate you and your input to my problem. It may sound like nothing to others, but your input helped me solve my problem and I want to share it with others. This is a situation which I'm sure will be experienced by others. It's easy to fix once you have good information about the problem. You have helped me and I'd like to provide some input for others.
I jacked the car up using a floor jack. I blocked the rear wheels, and put jack stands under the frame in the front end. Your input helped me locate the A.C. drain, but it took several attempts for me to find the drain hose.
The A.C. drain is located almost in the center of the car, high in the dash. I'll describe the location from the underneath of the car as that is where you'll have to unplug the drain hose.
The A. C. drain hose on my 2005 Buick LeSabre is located high above the point where the manifold meets the catalitic converter. These cars are so low to the ground that I wouldn't have found it without jacking the car up and putting it on Jack Stands and crawling under it.
Above the catalitic converter is a small drain hose coming out of the dash. It's approximately a 1/2 inch line. It extends out of the dash approximately two inches, then bends down in a 90 degree bend for approximately three inches. the end of my drain hose is like the neck of a balloon. Coming out of the dash it is a round hose, but at the end where the water comes out...it has flat sides that go together. I found some sort of gunky matter in the outlet end of the hose. The water coming out was only a drop once in a while, nothing like it should have been. The blockage caused the water to back up inside the car and spill into the passenger side of the floor board.
I took a 5/32 inch copper rod approximately 25 inches long and used it to open the drain hose. A couple of flicks of the rod and splash! I got wet. The drain was open, then I had to address the moisture inside under the floor carpet.
Wishing everyone well and hoping your problems are small.
