1992 Buick RoadMaster blower motor location? Sign In

I have a 1992 Buick RoadMaster and have been trying to locate the AC blower motor for a while.

Compressor works (I can feel cold air when driving) and I hear something "shift" when I press the defog/defrost button, but there is no air movement, motor is not moving. I've been living with no AC, no heat for a couple years but a successful blower motor replacement in a Dodge Caravan encouraged me to try this.

I've tried to locate it under the hood near the firewall, and have taken off the panel under the passenger dash, but there's so much 'stuff' under there, I'm uncomfortable tearing it apart. Also, the last year or so I disconnected the lead to the compressor to shut it off, since I couldn't use it.

A good diagram would help. The only diagrams I've been able to find on the Internet were for 1993 and 1994, but don't look any thing like mine...can't find anything on a 1992...

Pretty sure (it's been a couple years...) that the blower motor was squealing when it finally died. As I mentioned earlier, I just replaced a blower(squealing then died) in a Dodge Caravan and also had to replace the resistor (I'm assuming because the motor died and killed the resistor), so I'm hoping this is the case with the RoadMaster, if I could only find it!

It's under the dash on the passenger side. You have to remove the dash insulator panel to see it.

the link is a drawing I made of what I saw.

I took off the front panel and see a cover over a round shape. is that it?

That's probably it. it will be round and it will be in that area.

If you get to it, whack it with a hard plastic hammer and it may come one if has power. Still would need to be replaced and watch out for the squirrel cage as that little nut is likely reverse threaded! Hammer is awesome and all here are here to help you,
