Question about 1993 Oldsmobile Ninety Eight

1 Answer

The blower motor on my 1993 Oldsmobile 98 Regency Elite won't turn off. I followed the wires from the fan (Purple and black) and they lead behind the dash. Can't figure out which relay switch they go to. Any help?

Hello. I have a 1990 oldsmobile 98 regency elite and I can't get the blower motor to work. I tested all the wires for currency and they good. I also changed out the resistor as well with both relays. I...

There have to be something you missed during your troubleshoot. If the switch to turn on the a/c is good, since it turns on the a/c compressor, then it must be a wire that it's not connecting, or (not sure if there is any in these vehicle) a sensor, which controls the speed of the a/c blower. I'm sharing this because I took apart my vehicle's a/c blower motor, and right at the firewall, there was a sensor. If that is damage, then the blower won't work.

Blower stays on when car is turned off won't stop running until I disconnect the battery cable, tried the blower fuse that didn't work. 1995 olds auroa

If you pulled the 10 amp fuse in the I/P fuse block and the blower still worked than the the blower motor module is most likely the problem. It is fed by a 30 amp fus4e in the fuse block under the rear seat. That fuse is always hot and always supply power to the blower motor module. If you pull that fuse and the blower stops than it's pretty likely the blower module is the problem.

The blower module is located near the blower motor. It is usually held in place with 2 screws and will have four or five wires at the connector.

    1991 Olds 98 Elite heater blower motor continues to run with key off. Will change speeds with controls but will NOT shut off..

    if you haven't got your blower fan fixed yet, im sure it to be the same as mine, the blower motor relay which is out on the firewall under the big fuse block. take plastic cover off over the fuses and move the fuse block out of the way and you will see it staight under that. should be two screws holding it on.

    Where is the starter for a 1995 oldsmobile 98 regency elite

    The starter motor for your Oldsmobile is mounted at the front lower part of the engine, just behind the radiator.
    Book time to replace by an experience person is 1.1 hours.
    If you are looking to do this yourself, disconnect the battery negative terminal and isolate it.
    Remove any covers or braces in order to access and remove the starter.
    Remove the wires to the solenoid on the starter, then the bolts retaining the starter to the engine.
    There may be some shims between the starter and the engine. You may need to replace these with the new starter.
    Hope your repair goes well.
