Messing around with interior lights (Vol, Temp, ECT switch) and now my "night" lights wont come on. Climate and radio display both working fine but the buttons are not lighting up.

Checked drivers foot panel fuse box and the "PANEL" 7.5A fuse is blown. Not really sure what this fuse regulates. Could it possibly be the culprit? If I had any fuses lying around I'd go check but wont be able to get to it til tomorrow..

 

That is definitely the problem. Always mess with electronics with the power cut, or shortages and blows will happen. Buy a bunch of fuses extra if you are modding interior lighting.lol

 

Yep, so it looks like that's what the PANEL fuse does..

I have removed everything from the car to do the work but I had to plug it back in to test it. lol, obviously I have some work to do.
