94 roadmaste heater moter wont blow, tested motor

If you have climate control it could be the main processor. Something could be shorting the blower relay to keep it on. You would also need to check and see if the system is still full of freon.

Sounds like your crank position sensor went out.

Vacuum leak or bad IAC motor?

there is a module that controls the motor located arend the blower moter that will need to be replaced. Not sure if this is available other than dealer. check with auto parts stores first. I would ask for blower motor control module.If this helps please reply and good luck

Replace the complete blower moter. The internal electronics have gone bad and will not shut off as it should

have you replaced the temp sensor? if not get 1 from dealer cause the 1's you get from autozone ****! cheap parts made in mex,

If you have the Auto temp control; and you have checked the coolant level then you may need to replace the module that is under the dashboard on the right side footwell,. this is a common problem on these cars. When you remove the plastic under dash panel, look up and there is a module in the duct for the heat that determines the temp so the Climate control works correctly. I pulled mine out of a junkyard car and saved about 80 bucks.

rheostat playing up but where it is or how you get to it i havent a clue,sorry not many of these beasts here in spain.

yes sir you can jerry rig a toogle switch. ran a hot wire, to the pos. side on the blower moter, and ground the blower motor to the frame of the car..not a perfect fix, but cheap and will work..keith..

It's a 1995 Buick Roadmaster. I believe it's the blower motor control module. I think it's under the passenger side dash and if I can get it out, how can I get it tested?
