my 92 Eldorado blower motor comes on and blows hot air thru the defrost vent when the engine gets hot and wont turn off unless I turn the car off. the car doesn't overheat, but I changed the thermostat anyway. can anybody help me?

The mode is vacuum operated and defrost is the default mode. If you can't control where the air blows from, you may have a vacuum leak.
Can you control temperature?
Can you control fan speed or fan on & off?

yes I can control the temperature, that's until the vent light comes on and it starts blowing, then I have to turn it off because the engine is hot. but both fans are working.

Sounds like the blower is on it's way out and you may also have a vacuum leak.
