If the blower motor randomly and intermittenly quits and does not work, chances are good the blower motor itself is faulty, if the blower motor does not work on all fan speeds from low through high, it most likely needs a blower motor resistor.
I would look into the blower motor resistor module
The blower motors only work with the engine running. If the blower motor has three wires on the electrical plug, then the blower motor module is built into the unit & it's very expensive. Sometimes, you can tap on the motor with a hammer & it may work or slowly turn. If this is the case, replace the blower motor.
Many reason: blown fuse. seized motor. Faulty switch. Broken wires. Failed ballast resistor pack. These are the 5 i think most likely.
Blower motor control relay under dash behind blower motor is bad or has water in it from cabin filter port.
Check the fuses first and the blower relay.
Could be a blown fuse. Make sure the blower motor is not burnt out. Could be a bad relay switch. Make sure your dash controls are working properly.
try wiggling the wires at the blower resistor if don't work then tap on blower motor
I would suspect the blower motor speed resistor is bad.
I would suspect the blower motor speed resister is shot.
First thing to check would be all your connections..make sure you have a good clean ground... if all your connections are good then i would say your blower motor is overheating and shuting down(replace it)
Bad ground? or a loose connection.
If you only have high speed I would blame the blower speed resister. If you have no speeds and the fuse is good, I would blame the blower motor or the switch.
97 lesabre buick gas meter doesn't work can we fix it?
Start with: Possible control, blend door or blend door actuator, low pressure switch, leak in system.
Replace the resister, if that doesn't work replace the blower motor.
Probably a bad blower motor resistor
Yest, the Buick LeSabre from 1992-1994 is the same exact car, inside, outside, underside. Everything is identical, except say for the trim packages and options you get on them. Therefore, yes the cassette radio from a 1992 LeSabre will work in a 1994 LeSabre.
its the blower resistor.
check the wireing harnesses
Same thing happened to my car. The blower motor and the resistor had to be replaced. It cost me . The dealer actually had the parts in stock because it happened frequently enough with the Echo that he wanted the parts on hand. If it is your problem, you may be lucky enough to find a rebuilt blower motor.
If the blower works on slower speeds only I would suspect the high speed blower motor relay (under the hood in the power distribution box) or the switch itself. The blower speed resistor is working if all the slower speeds work.
It might be your resistor, does it work on 4 but not on 1,2,3? If so, you need a new blower motor resistor.
your blower motor resistor is most likely failing. sometimes that's an indication of a failing blower motor, but typically, it's a resistor module failure
add atf. take to local oil change place have them drain and replace filter and fluid.
Blown fuse, defective blower motor resistor pack, defective blower motor, a bad switch, or disconnected or loose wiring.
