You should find your answer. From what I remember the first free option is to take the heater blower fan out and soak it in WD40 get it spinning and lube it up. There's a guide to it in the wiki pages just have to read through..

Does it also do this with the engine running and set to max, or does it work on max?

Given that there is dimming of the lights, that would suggest a large draw and the motor could well be stuck. Gaining access to it is simple and is listed in the wiki (here: http://www.e30zone.net/e30zonewiki/inde ... nly_on_Max ), removing the motor is a right pig due to the clip that holds in it place.

As is getting the clip back in around the motor...

That's one of tomorrow night's jobs for me, it'll be especially fun as I bent the clip slightly when removing it.

There's a small hole on the tab of that clip. I stuck a bradle in it and pushed down on it equally as much as i pushed my tongue into the back of my front teeth.. until either popped... thankfully the clip popped into place first..

Its a peice of piss to change the motor!

It should take 20 mins tops...
