98 buick lesable blower motor stop working?

Could be the switch or wiring. The resistor can be checked with an ohm meter but they are substantial and not prone to turning up faulty when new.

Its faulty blower motor resistor. The low and medium speed on blower motor is controlled by resistor and its actual speed is high. So because resistor is not working, blower motors actual speed which is high is working.

It can be faulty blower motor or faulty blower motor resistor. Get the blower motor inspected. If it's faulty it has to be replaced.

Check everything again the motor could have shorted out.

I assume you mean that the blower motor quit running. Did you try it to see if it will run on any speed? If it won't run on high, but runs on the lower speeds, it is most likely a bad blower motor high relay. If it will not blow on any speed, it could be the blower motor fuse (In which case, you must find out why it blew or it will only happen again.) or the blower motor itself. Buick Century is known to burn the connector at the blower motor. There is a replacement connector available in the aftermarket to repair this. I personally recommend replacing the blower motor also if it is a burned connector because the blower motor is usually partially shorted internally, which is what causes the connector to get hot and burn.

GO TO THE JUNKYARD FOR ANOTHER BLOWER MOTOR. LOOK BACK ONLINE FOR INSTALLATION INSTRUCTIONS

might have to remove squirrel cage and assem. on new motor

See if the blower motor will run with a wire ran to it from a 12 volt supply from the vehicle.If so the blower relay needs to be checked to see if it is the problem,if it checks out,replace the control head,the part that does not light up anymore.If the motor does not work with 12 volts ran to it,replace the blower motor.

check connector at blower motor, common problem there.

Try putting in a.c. leak detector first to pinpoint where the leak is coming from...That can be a costly repair if you take it to a shop especially if you can't find the leak yourself !! Well best of luck..hope this was helpful

Is there power at the compressor? If not, check the level switch located at the rear of the vehicle (connects the rear axle to the body via a small arm that moves with body up/down motion)
