warning lighs/buzzers not working

Was your speedo and tach still working?

 

Sounds more like a loose wire harness to me.

 

Mine blows the acc fuse and all of that quits working. It's sporadic so I am having a hard time tracking it down. If it is just the trouble lights and buzzer I would check wher the wires plug into the back of that panel. I know that in a 99 Pete it has two sets of 5-6 wires per set. One set on the left and one set on the right. If your is like the PB the wires that plug in on the right control what you are talking about. The wires on the left would control the lights that are working. Check and make sore they are still plugged in. If your speed, tach, odometer, voltmeter all have quit working also ( like mine) you may have another problem.

 

There should be a fuse labeled warning lamps in the fuse panel. This fuse controls that panel.

 

I lost my lights on a couple things a while ago, when the buzzer stopped working I replaced it ($100) still didn't work: turned out to be that whole little panel had turned to s and was all good when I replaced that ($300 & it comes with a new buzzer). May consider taking it out, cleaning contact points (possibly exchanging with a known good one to verify) and reinstall see if there's a continuing issue.
