    mine does the same thing. along with you cant shut the heat off once it comes on by itself. i have to wait til the A/C light goes on then i can hit off and it works. but it just stays on for different periods of time. sometimes it doesnt come on at all. no buttons work when it turns itself on

The control assemblies on this model have a high failure rate, and can create all sorts of erratic intermittent symptoms.
You can take the vehicle in to your local Dodge dealership to be diagnosed ( A Chrysler DRB-III scan tool is required to test this system), or you can try replacing the control assembly to see if it resolves teh problem (it most likely will).
Your mechanic can easily replace the control assembly; it is a completely electronic unit that is no more difficult to replace than a radio. A new control assembly costs between $275 and $440 from the dealer (depending on what particular A/C system you have); used ones from your local salvage yard generally cost around $100 or so.

Heater problems


Could be one of several things. Your car has automatic climate control that takes air temp and coolant temp into consideration in controlling the heater components.
The heater blower will not come on until the heater warms up. So the engine thermostat could be faulty and the engine is taking a longer time to warm up.
The electronic controller adjusts blower speed. And the blower motor could be going bad.
You may have to get a shop to take a look at it - someone with the books and tools to test the system.

1991 cadillac deville NO HEAT


I had the same problem in my 1991 caddy, and turned out to be the blend door. It is located in back of the glove compartment. There are two kinds, the automatic blend doors and the manuel ones. Since the temperature is automatic and programmed to stay where it is set, it would be an "automatic blend door". Not a hard fix...
