Unknown button?

[franko2490]

it does pop if you push all the buttons of the windows to lift them all up
try it !

Yea, don't play with it - it's fine the way the factory set it. LOL.

It's there cause the engineers were worried that since early BMW's (all e30 and a few e36's) use the switch to directly drive the motors (no "relay" is involved) that the contacts might arc (big electrical spark) so much that they might fuse together, and run the motor forever - or until fire, smoke or a dead battery.

Has anyone even had their window switch pop ever? Don't think so - I've never heard anyone mention it.

I've seen a couple melt but that's a couple out of thousands.

^wow, crazy. I just noticed that little adjusting screw your talking about.

[george graves]

Actually, only the buttons that have red on the sides(you can see it better if you press the button) are a window "circuit breaker." It even has an adjustment screw on the back for setting the threshold.

All the other ones that are a completely black button are merely a switch - and a pointless one at that.

So verts and 87's have the swith on the console. No hole in near the shifter

[smonkbmw]

That's because they was there in the HVAC panel till 87. Then in 88 and on, they put the breaker switch on the console.

yeah so there!!! lol.

Mine too.

[dj2xrated]

press that when your at 6k Rpm's and you hear the vtech kick in.... it looks like a window switch.

[steinbachphoto]

Mr.

this guy is truth.

if you look on that switch that you have circled you can faintly see the icon for a window with a disconnect symbol on it

then again you have a vert, so that is where the switch started at.

You're all wrong.

It's a circuit breaker for the windows.

Although I guess you can use it as a window lock... although there really isn't a purpose for that in a coupe. The 4-doors have a separate window lock.

[learningcurve86]

it releases the rabbits from your tail pipe. PRESS IT! THEY'RE GONNA DIE!

[Bimmerista]

Its the button that releases the blinker fluid to cool off the muffler bearings

[E30 Cabrio]

Push the button, then try your power windows.
