Electrical gizmos in '84 190D

The electrical gizmos in my car has expanded; They now possess the brakepad-indicator as well! It goes on when I switch off the car, and shuts of when I set the key to ignition - in other words; It does exactly the opposite of what it is supposed to!!!

I now have three faults needed to sort out before the 23rd (inspection time!)!

1. malfunctioning windshield washer - doesn't wipe more than once
2. malfunctioning rear window heater - goes on automatically once in a while
3. malfunctioning brakepad-indicator - doing exactly the opposite of what it should do..

I am quite positive that the first two ones are related to the combined relay as I really don't know what else it might be caused by.. But the third one really got me puzzled! I removed fuse 13, which killed the light, but when I then started the car, it came on as usual on ignition, only to fade in and out once the car was started..... When I put the fuse back in (with ignition off) there was a spark, showing what I already know; Power runs through it even when power is off!

you wont like this answer nor will most...

but how about removing the instrument cluster and seeing what you see and if nothing looks funky- like a bad connection at bulb or anything else- how 'bout you pull that idiot light? that'd be my poor man's way of fixing it if nothing is too obvious or if it's too time consuming to troubleshoot.

I think you're right; I need to pull the cluster to see whether something is fried back there - My guess is really that something has "tapped into" the light somehow, since it works in a different way when I remove one of the fuses..

Just pulling the light without figuring out what's causing it is no option for me - I need to know that things work properly! One thing is for sure; I am sure as hell going to install the fire-extinguisher I bought recently, electrical problems is no joke!
