SOURCE: Heater control and windshield defroster temperature problems

It more and likely is the servo motor (s) that are the problem, when you turn hot to cold and defrost they cycle the vents in conjuction and are a common failure on this model.
The ones that fail are accessible if you remove the right underscuttle panel and the glovebox.
Black motors with a double wire, usually have a red connector on the end.

Speedometer, cruise light , ac/heater control doesn't work


Sounds like someone needs to do some more troubleshooting first. Changing the cluster is not a simple matter since your mileage will be different. And the cluster is on a different circuit that the ac so one should not affect the other.

Heater/AC Fan Problem


sounds like a shorrt to 12v to me. The wire is hot and the fan is shutting off because the blower is bad, getting to hot, it will bind, causing over amperage.

AC/heater fan on 1992 Buick LeSabre only works intermittently


Could be a bad control switch, relay or connection and ground at motor itself. Since it's intermittent, check voltages when it's working, then again when it's not. Wherever voltage stops, that's what you need to replace. Don't wait on this...when completely inoperative it gets much harder to find the problem!
