If it's climate control, then fan controller has failed. It's mounted in the fan casing, have to remove glovebox for access.
The early controllers may be repairable, most likely one power mosfet has shorted.

agreed, likely due to blocked scuttle drain

With the glovebox removed, look up and you should see the fan casing. The controller has two heavy gauge wires and several thinner ones. You may have to remove two vacuum switches to give clearance, if it hasn't been removed for a long time it may be a bit stuck.

speed controller is bolted to blower, which you'll see when you get glovebox out.

Not as easy as expected, and officially should disconnect battery as you have to loosen airbag.

Hi Phil

I had a similar problem on my old 96 OmegaB, I used to pull the fuse as well and the fix was the regulator unit behind the glove box connected to the fan from what I remember.

It was a bit of a bum to get to and I think the replacement part was about £90 so a bit risky but it fixed mine.

Good Luck
