Good luck. Hello. Not to say that my friend above may not be remotely right, but if your problem is that all of this climate control failed at the same time; the only common linkage between the rear defog and blower motor and heater/ air conditioning is the Electronic Climate Controls. It's in the middle of your dash. They run about $114.00 USD on gm parts for less websites, or you can get one at a salvage yard. It's a lot cheaper than just throwing parts at it like my friend above. To be sure get a COMPUTER SAFE test light and check the brown wire and the lower of the two orange wires. If both tested light up then your control unit is bad, if not then check your fuses. There are two which are necessary for proper functioning of the climate controls.
Hi I also am trying to fix my 1996 olds 88 with the same issue. Where and how large is the Electronic Climate Control unit?
Check fuses Check for loose connection in fuse block
I have exactly the same problem on my 2000 Still looking for the answer
Check that the wire on the rear defroster is connected to the defroster. If broken off repair it.
if there is a lot of snow or ice on these vents located at the bottom of the wind shield under the wipers that could be the problem if you live in a cold environment.
Check the coolant temp sensor, or just replace it if you have the money to burn.
"What" on the suction line of an air conditioner indicates a problem?
The defroster is a thin filament that is run across the rear window sometimes inside that heats up to remove frost. first off does the switch light up when pressed? is there power to the connector at the back window? if so then check the filament itself for breaks this may be the problem, if not then it may be a blown fuse, or bad connection.
One reasons a Dodge W 250 defroster may not work is the blower motor relay. This can be replaced easily. If it isn't the relay, there may be a problem in defroster door binding. A mechanic will be able to determine the cause.
Had the same problem. Make sure the rear window is all the way up. This is probably a safety feature? Your wipers and rear defroster should work.

you have a sensor problem.
No you cannot sue unless it was sold with a warrenty.
The AC is probably coming through the defroster because the air door is stuck. The door is behind the dash and is vacuum controlled. A vacuum leak or bad door will cause this problem.
Could be a vacuum problem--either broken or disconnected hose or bad vacuum motor under dash or coming in through firewall Defrost is the default position for this system
Years and years and years and they quit making them because of this large problem to their new car sales. Oldsmobile had an excellent engine,
i got a problem with my Oldsmobile alraro 99 the temperature gaurge went up so height and i want to know how i fix it
It's probably a problem with your catalytic converter.
Check the bulbs first. I had the same problem on a 94 Oldsmobile and it was the dimmer switch. Replaced that and fixed the problem Check the bulbs first. I had the same problem on a 94 Oldsmobile and it was the dimmer switch. Replaced that and fixed the problem
Often when a vehicle air conditioner gets loud, the problem is due to a belt. You should take the car in to have the belt checked.
Yes because lice has always been a problem and they probably had no access to shampoo or conditioner.
The RPMs and the engine of the 2001 Oldsmobile Alero might surge if there is a problem with the oxygen or fuel sensor. It may also surge if there is a problem with the fuel injectors or the fuel filter.
Did you check the AC fluid? That is sometimes the problem.
My air conditioner makes a snap sound when I turn it on and also makes my engine chug. The defroster does the same thing. What's the problem? Please help Haynes makes repair manuals for specific car models and years. You can buy one at most automotive part stores for about $25.
It is important to keep the air conditioner clean and know how to remove mold as it can reduce the efficiency of the air conditioner and also cause a foul smell . You should clean the condenser and the indoor unit.
Check to make sure your rear window is not down a little bit. I could not get the rear w/s wiper or the rear window defroster to work until I lowered the rear window and then closed it again. Problem solved. Hope it works for you, too !
