Isn't the diagram for the fuse box on the back of the fuse panel? If not, you could simply open up the fuse box and figure out which fuse is popped, then replace it with one of equivalent amp rating/color.

Had a similar prob. Was working on re-routing some wires (prob hadn't been moved in 24yrs+)around the fusebox brake booster area cos I could hardly get the fusebox cover out the way it was.. way to tight & in fact the cover was damaged on one corner prob from forcing the cover in & out. Disconnected some of those wires, cleaned out the connectors & pins & plugged them back in.

Next thing you know & not right way, I'm driving along & the windows go down but not up. Lost the tach & turn signals & a few other things ..forget now.

Figured right away that mighta had to do with the wires I was fiddlin with under the hood but first thing I did was look at the fuses & was not happy to see that they all appeared to be intact.

Figured I should also rotate 'em 1 by 1 .. longshot but maybe the connections were corroded/dirty & did have a combo of alum & copper fuses which I understand, copper is the way to go & the alum ones are problematic (dissimilar metal).

Did the top row & was looking for action from the turnsignals which I could see whilst spinning/massaging the fuses & zip.

Went from left to right on the top row & then started right to left on the bottom.

BINGO, got some action from the 3rd fuse from the right, bottom row & that was the whole problem.

Cleaned out the whole fusebox area & connectors after that & lubed it.

Check the under side of the fuse cover, there should be a list.

EDIT: You may want to list further questions on the 126 forum, seeing as how that's the chassis you own.

Thanks!

gottarollwithit--- i am guessing that there once was a fuse diagram inside the cover ... guessing it was paper nothing printed into the plastic... somehow in 24 years it disappeared... amazing huh?

300td85---hard to tell if some of the fuses were good or not... had a lot of trouble with using a test light... soetimes it lit sometimes not... so i did the only logical thing a girl could do... i replaced all of the fuses... i eliminated the aluminum fuses and used all copper...

rmac58--- thanks will post there... new to this site!
