88 535is fuel & temp gauge and windows don't work

[FB535M635]

My fuel and temp gauge had been working intermittenly until yesterday when they stopped altogether. I'd start the car and no fuel and temp then when I started moving they'd come on and the test light blinks until I hit the brakes, then all was well. Yesterday they never came on at all in 3 seperate trips. Also when they don't work the windows don't work either. No fuses blown. Is there 1 relay that controls all these items? Any ideas? Thanks

Even though a fuse might look good, it dont mean that its getting current flowing across it, you can check with a volt meter if you are getting current flow, and also check the contact, you may have to bend the fuse holder or file it down for a better contact.

I don't recall offhand which fuses control these, but I'd definitely check all grounds under the hood ie; motor>chassis ground straps, alternator accessory lead, & battery accessory leads.

Aside from that check here http://wedophones.com/BMWManualsLead.htm.
for an ETM to assist you on this.

crappy 8a fuse, wasn't visibly blown but doesn't work either. Issue resolved, I should probably not assume the worst every time I have an issue. Thanks

Well, now you know about those fuses.
