Wow... The electrical gremlins attack!

Grad student in what?

Search around for the electrical troubleshooting manual (ETM) for your model. They are freely abundant on the interwebz. Get a circuit tester. Work through one problem at a time.

Edit: also read up about electronic circuits, relays, wiring diagrams.

Got one of those manuals. It's all gibberish to me, man. And I'm a grad student, so although I'd like to take your advice and read up about all that stuff, it'd take me months. Was really hoping someone had a similar experience and could chime in.

Blinkers are something I can't do without. ATL drivers would have no clue what was happening if I used hand signals. They'd probably think I was flipping them off or something.

For your speedo prob check the wires coming off of part #8 in the diagram

For your blinkers... R your cluster light blinking fast or slow??? how do the hazards behave??
check the shared ground between the blinker and the side marker.... buried behind the front bumper

Now that I can do!

Right now, nothing with my blinkers works at all. Perhaps I should have added that my right blinker was blinking fast before this happened. However, they were never lit up on the dash. I could hear the clicking and the exterior blinkers lit up properly, but I've never had working lights on the gauge cluster. Last I checked the bulbs are good, but I can give that another double check today.

Thank you guys for the help!

Jésus Christo. This is insane. So I just picked up a new (to me) 1989 325i. Did a full tune up and such, the motor is running like a champ (for an M20). But holy cow, this thing has electrical gremlins out the wazoo. I searched all over Google and looked through a couple dozen threads here, but if I missed something pertinent, I apologize! Feel free to point me there. Anyway - Here's what's up:

1. My gauge cluster isn't lighting up at all. (No, it's not a fuse. No, it's not burned out bulbs [see #2 for more info].)

2. Up until a few days ago, my turn signals worked fine (aside from not blinking on the gauge cluster). Now, if I signal, my gauges light up, but my signals don't work??? WTF is this sh!t.

3. My speedo isn't working. All my other gauges work properly.

All of the fuses have been replaced. I know little to nothing about electrical stuff. The best I've done is install a CD player. So speak simple to me, please! Thanks in advance!
