1994 Oldsmobile 88 BLOWER MOTOR

Hi STANOLEE Welcome to 2carpros and TY for the donation and selecting us as your auto repair site Feel free to ask questions at anytime and Merry Christmas and a Happy New Year 2010

Find the blower motor relay in center rear of engine compartment, remove it should stop the blower motor if so try swapping it with a like one and see what happens

See N2 below

Okay remove fuse no.3 30amp if it stops -the red and purple wire are shorted together within the wiring could be at the relay'

The purple wire is coming from the power side of the blower motor and the red is coming from the fuse-if this 2 - touches it will constantly power the blower motor

The purple wire is the positive side of the blower motor if there's no power here the blower motor will not come On its the power feed wire.

The red wire is coming from the no.3 30amp that has power at all times no switch control on it then goes to the relay when the relay is energized power is transfered to the purple to fire up the blower motor.

When you pull the blower motor relay this cuts the power off between the blower switch and motor-and if this 2 wires are shorted together the motor will contantly run

Hmmm. Auto control HVAC

Okay the red wire at the module should have power at all times which is coming from fuse no.3 30amp

Do you have a purple wire on the module

I want you to remove fuse no. 2 and 3 did the motor stops?

Replace the module
