I sent my '89 in for a tune-up a couple of weeks ago and just got the car back today. It runs better than it ever has -- not to mention we did this at the right time, as we found three weeping fuel injector rail hoses during the service -- but on the way home tonight I realized that my turn indicators were not working.

Then I realized my brake lights weren't working, either.

I forgot to test the reverse gear lights. My running lights work with the headlights on, as do the tail lights. And the hazard light switch works properly. But none of the brake system lights (either of the mains, or the center brake light) are functioning.

This is too much of a coincidence to all go down at once, so I figured I'd ask whether there was a common fuse or relay that controls all of it together. My shop is very attentive and will make this right as soon as I make them aware of it, I'm not worried about that. But if I can save myself a trip back up there and another day without the car, I'd like that.

Hope this helps. Might be 10 amp fuse #5 main fuseboard.

Hopefully, it will help my shop. I'm not an expert at reading electrical schematics; looking at that link, I can't find an obvious commonality between the two systems but I could be overlooking something on the schematic and not know it.

Fuse no5 in the main fuse panel under the steering wheel is common to doth brake and turn signal lights. Give this a check, it's where I would start.

 

Well, malc4d, Warren, you were right. But it still took me an hour to get it completely fixed.

The cover over my main fuse panel is missing, so if there's a fuse layout map printed on it, I don't have it. Also, there are 20 fuse positions in my box (19 plus 1 dummy); in my owner's manual, only 12 are listed.

On top of that, only FOUR of the fuses in the box appear to be the correct amperage. According to my manual, the brake/signal lights are supposed to be a 15a fuse; in the car, that fuse was a 10a. And yes, it was blown.

But I couldn't figure out which fuse "fuse no5" was for the longest time, because with all my ways of telling which way was up or down being screwed up, I finally just had to manually pull every fuse and inspect each one. PREVIOUS OWNERS!!

Hey...... That's great. Glad I could help

 

Yes, thanks very much. Having that schematic for the future will save my shop a lot of guesswork.
