Default 91 Brougham Blwr motor won't stop (even with ign off)

I have a 1991 Brougham. The blower motor keeps running no matter what. I have the automatic climate control. What should I look for? I've heard that the resister can go bad. Is there anything else than could do this? If the resistor is bad I will just have to let it be because it'* too expensive for me. Any ideas?

Oh and also. The Hazard flasher is out. And Parking Break Automatic Release. And power to Drivers side rear view mirror.

If you have auto climate, you have a blower module instead of a resistor block....is will be located in the same place as the resistor block.....can follow the purple feed wire from the blower motor back to it...located left of center of the firewall, under the relay brackets....


Sometimes, a bad blower motor can create a "spike" that takes out the blower control module....it'* very rare, but it happens....

As for the other problems, have you checked all your fuses in all locations?

But I do have a resistor. I found it just to the left of the blower motor. I took it up, there was some white gew in between the plastic part and the metal part. I took them
apart and cleaned it up but with no change as to the blower.

Are there other places for fuses than to up left in the drivers footwell?

if the resistor goes bad you loose speeds it doesnt stay on. and the goo is very necessary heat sink compound to dissipate the heat the resistor makes. i dont have a diagram for your car so i cant really give you a good answer but educated guess would be a stuck relay for high if you car has one or the controller is always calling for fan. i guess i would unplug the controller and see if it stops

That'* interesting! So two questions: 1) do I need to buy new goo and what is it called? Where can I find it? 2) when you say unplug controller do you mean the module on which I select temperature on? The buttons with display box?

Thanks again!

If you have auto temp, you have to have variable blower control, and the only way that is possible is with a blower module, not a resistor....the blower module will have a large aluminum finned heat sink on it....

Yes exactly. That'* it. Electronic Climate Control Power Module (ECC). That'* the one I found. So. I guess my only solution is to by a potentimeter.

No, you need a blower control module.....and hope that it wasn't the blower motor that took it out......
