Ok, everyone, I'm not on drugs here.... but I think my Bonneville may be...
A few weeks ago, a friend pointed out that my back-up lights were on any time that my headlights were on, either manually or automatically. The problem disappeared for a bit, and I shrugged it off until it happened again a few days ago.
I couldn't get the back-up lights to go out, though when I put the car in reverse, the lights got brighter. I assumed from that, that a bulb must be out and grounded across, causing a backfeed through the back-up lights, and I started investigating. While I was messing with the lefthand taillight assy, the back-up lights went out, but so did my lefthand taillights. I now have no lefthand taillights or front marker light on the lefthand side, though all the turn signals, brake lights, back-up lights, etc. work just fine on the left and right.
Using my multi-tester, I checked wires to the taillight bulbs, and while I have brake light power, I'm getting nothing to the taillight wires. My assumption is that I have no power to the front either, though I haven't delved into that end of the car.
Does anyone have any insight on what might be causing this? What fuse are the tail and marker lamps on, and would the righthand and lefthand lights be on separate fuses? Could it be a relay that'* 'half' bad letting some things function, but causing my park lamps to not work? Would anyone have any wiring information in form of a diagram or such, that might help me in tracing my problem?
If anyone could offer a suggestion, I would be most appreciative! Please reply here, or e-mail me directly to make sure I see your reply - firstname.lastname@example.org
Thanks in advance to all!
