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?

How do you repair a non-functioning rear defroster on a 2003 Oldsmobile Alero?
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.

Why doesn't my dodge w250 defroster work?
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.
