Fuse 4 is blowing as soon as I turn the key to accessory on in my 87 325is. I've removed the hazard switch and it still pops, so I'm guessing that means the active check control system is where the short is? Anyone have any ideas on where to start? The check panel has a few lights always on because the sensors have been removed (i.e. washer fluid, aftermarket oil pressure gauge etc). The only one that doesn't make sense is the brake light check; the brake lights work fine.
Before I took the switch out, the hazards would work on the driver front and both rear blinkers, but not the passenger front, despite the running light and side marker being lit up with the lights turned on. Blinkers dont work because fuse 4 is popping before I can try it. I put new side marker bulbs in and both the dual filament bulbs in the front (running light / blinker) look brand new.
Edit: Forgot to mention, the blinker relay clicks and works when the hazards flash so I'm assuming that's not the problem.
