Sounds like you've got a bad earth somewhere arond the general unit - checked the state of all the earths (wires & screws) under the back seat? Two big earth blocks either side like bus-bars. Suspect the flasher is getting a voltage pull-down from the motor load (when motors operate) that simulates the hazard switch.

Cheers.


How bizarre that they work different ways.
But mine is going haywire, flashing for no reason, like when I open the sunroof, open a door, turn off the ignition, etc.

Dealer mechanic said it was the crash detector switch, and put a new one on today. Opened the sunroof on the way home and the flashers come on.
Damn.

Ever since I bought my 90 735iL (160k mi now), the flashers have not worked properly. Since I do not have access to any other E32, I need to know whether a normally functioning flasher switch button is supposed to stay 'pushed in' when the flashers are operating. I can get my flashers to work by pushing the button, but must hold it in by hand. Once the button is released, the flashers stop. Is it a mechanical switch problem or is there some sort of relay that quit?

Thanks!
