DP-924S

Hello All,

The heater motor on my 1987 924S will not work at any speed. The AC fan does work fine.

Any tips as to where to start? I have read up on a couple of other sites but have found nothing that helps so far. I was going to try to open up the housing where the blower sits but don't know how to get at it.
How do I open up the blower housing without breaking things? It looks to be glued down.

With the fan not going at all, is it possible that the problem is a resistor inside of this housing, or should I start somewhere at the fuses? I'm not adept at electrical diagnosis so I'm really hoping this is just a plug and play part replacement!

I'd try fuses along with this:

Thanks Chunkerz. However mine is an older version than this. I have the 87 924S which I think is similar to a pre 85.5 944. The fix you are referring to looks to be a new model.

You could try a new 3 way fan switch--fix? maybe.

The blower motor resistor is on top of the AC/heater core box- passenger side. Cannot get to it unless you drop the entire unit and disconnect the AC lines.
