Heater/AC fan speed controller 1994 Olds 98

The battery gets weak after sitting a few days.

Traced it down to about 100ma constant current draw through the blower circuit.

I suspect the electronic fan speed control.

Where is it? Behind the temp display and climate controls?

Any suggestions as to how to remove that part of the dash?

Any and all suggestions appreciated.

I found it. It is uunder the fuse block just beside the blower motor in the engine compatrment.
Now paying for it is another story.
