Electrical Gremlin

Basically my Tach, MPG, OBC and ICV aren't working right now. No power going to ICV (tested it to be sure, car is running like crap). Also no interior, glove box, or trunk lights work.

Now, fuse #21 controls all of the above, as well as fuel delivery. Fuel delivery works fine, car has been running like this since Friday, and the fuse is not burned out (replaced it to be sure). I'm assuming there is a break somewhere down the line, does anyone know common areas for it to screw up? I'd really love to poke around but it's -15*C + windchill and I don't have access to a garage, so I'd like to know where to look. Right after the fuse box? Inside the knee bolster?

Thanks in advance for the help.

Nobody has had this problem before?

Never had this before but as a suggestion, take a look in the back of the Bentley there are some wiring diags that could help you out. There's a site with wiring diagrams but I don't have it bookmarked.

Tomek, if you can't find any wiring diagrams let me know, I can print some out for you at work. (im working on Friday) you can swing by and pick em up if you wanted also.


Check other fuses also. According to this break down, the tach/MPG could also be fuse #10

OBC could also be Fuses #12, 21 or 27.

Better to just check em all, if you have a test light touch each end of the fuses and make sure if one end has power the other does also. Not all of em will have power thou.

Thanks Trev, I've tested every single fuse (pulled it and checked continuity) and replaced all fuses that pertain to the non-working shit.

I'm goint to stop by on Friday for my much overdue alignment, so if you could have those print outs I would greatly appreciate it, the whole electrical section in my bentley is missing.
