Well its not quite that easy. You have an automatic system to control heat and ac. The control module may have failed, or it could be a blend door problem under the dash. You could try pulling the HVAC fuse or the blower fuse to stop the air from blowing, but it may still be hot when the car is moving. The fuse locations should be in your owners manual.
The seats are powered by a 30amp breaker which includes the circuits for the power motors. The signal from the control switch goes to a door module then to a memory seat module, then to the heater elements. It may be easier to disconnect the heating element for now, repairs will need a shop manual to test and trace the circuits.
Sounds like a bad actuator, the actuator is a small motor used to control a door in the heater box, there are a few doors to control temp of air and then one for mode (location of air blowing out ) and one for recir. try to locate and unplug it and replace the fuse and see if that stops the fuse from popping if it does then replace the actuator.
I'm confused, the heat still comes out but not on the window, are you saying the heat blow out air but not to the front glass? the air comes out on the floor but not the top of the dash for the front windsheild. if this is the problem then it sounds like the selector door is not moving. this car is listed as a 2000 daewoo. you will need to look under the dash at the heater box, you will look on both sides, from the pass/side and driverside. you will then move the selector control, this is the control that controls the location that the heat comes out of, you will locate door this way,by moving control to see if door is moving or linkage broke or if operated by actuator motor to see if motor is operating, hope this helps good day.
first check the heater fuse...then you want to unplug the fan motor lead and run it straight to the battery...if it works then you will need to check the resistor assembly..it is located on the heater housing right near the fan..it controls the different speeds for the fan and usually has 4-6 wires coming off it. If these don't fix the problem...try looking in the fuse/relay box both in the cab and under hood to see if you have a relay for the heater fan...as it may be defective
open hood,look in main fuse box for blown fuses,or bad relays to heater fans. the a/c fan should come on only when you turn a/c on at the dash panel only. it has nothing to do with the heat. if the heater blower fans don't come on, then look in the main box[fuse] for a blown fuse also. otherwise the problem is in the heater control module.[where you turn on a/c and the heat] that panel has a different fuse location.under the dash drivers side or on panel on drivers door at the door jam[where the door shuts towards the front of car,under mirror,but inside] look for fuse panel there also for blown fuse. hope this helps,but if not,recommend you seek a pro.such as cadillac
Check for a blown heater motor supply fuse,
Check operation of heater motor control relay,
Check operation of fan speed control switch,
Check heater motor speed control resistor pack (usually located in the heater ducting - in the air flow),
Check the heater motor runs if power directly applied to the motor- if not motor may be faulty.
My girlfriend has an eddie bauer as well. We had an issue where the blower motor for the heater comes on unexpectedly when the key is out and it's parked. And kills the battery ... in about 3 hours ... We pulled the 30A blower motor fuse under the hood ... I think it was called the ECC fuse Electronic Climate Control ... Go put that fuse back in ... sit in the car the blower for your heat may come on ... Maybe ... ours happened onlt 2x in 6 months, then it has been fine ... there are two possible solutions replace the ECC motor control (under the hood and fairly difficult to get to), or it could be the less likely Dash heat contol panel ... both are costly
