What cause the blower motor continue running on a 1995 Olds Aurora when motor is turned off.

I see quite a few of these that the connector on the blower motor side goes bad. One thing you can do is remove the panel under the passenger side of the dash. You will see the blower motor when you remove it. With the key on and the blower motor set to any speed wiggle/pull/twist the connector. If the blower motor changes speed or stops it need to be replaced.

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.

I don't know if there are any tricks. At this point you just have to wrestle it out. There seems to be a certain position that works but I don't remember exactly. I do know that gettting it out was easier than getting the new one back in.

If you haven't fixed this yet, your Blower motor resister module is bad. It is located to the left of the blower motor and mounted in the A/C air box. Just pull the right kick panel down and you will see it.

could be a faulty relay , pull relays out one by one and see if stops running

Could be the motor or the blower motor resistors. I would go with the resistors first.

Blower motor control module probably , but without testing that's just a guess . Do you know how to do automotive electrical testing ? Testing B+ to the module ? Do you know where the module is ? You can find a wiring diagram here , http://www.bbbind.com/free_tsb.html There is a fuse for the blower motor in the I/P fuse box , HVAC blower 10amp ,

it is underhood against fire wall passenger side under black plastic cover. right about blower motor. you willhave to remove the relay rack. disconnect negative battery cable to prevent short

this is caused by the blower motor speed control resistor module being defective, it is located just to the side of the blower motor under the pass side dash, it is held to the outside of the airduct by a couple of screw.

Run's continuously ? High speed , low , med 1,2, 3 . ????
Probably the high speed relay contact's stuck closed . The fuse for the high blower is hot at all times , low blower fuse is hot only with key on. It sparks becaused the motor turns on . If it had a short the fuse would blow . The blower motor relay is part of the resistor pack near the blower motor .
