My Bonneville dashlights won't turn on when the headlight switch is pulled half way or either fully out. My voltage gauge light, that I mounted under the radio , went out the same time the dash and the lights for the a/c controls did.

I checked the fuses. They are fine unless the pinch tabs are bent or not in full contact


Any ideas?

My guess would be the switch itself took a puke. Junkyard run or pay up the butt for new.

i should of pulled one out when i was up there Friday. dang.

now my display for the a/c, heat isn't showing when headlights are on...

I checked all the bulbs in the instrument... None blown.

Replaced the headlight/ twilight part with one from a junk yard... Still working the same... Not instrument lights.

Oh I also replaced the entire instrument with one from a junkyard and no luck. Even the volt gauge light bulb is good but no power/ light.

I also just replaced the DIC with one tht was working.

That was one of the first things I checked for corrosion. The connections were clean and looked basically new..

Thanks though for the link to the switch. And for your post.
