new electrical issues (Page 1/2)
cartercarbaficionado MAY 07, 08:14 AM
litterally just started happening...or I finally noticed while I was replacing my radiator and messing with stuff.
my brake lights light up my cluster lights, my right turn signal doesn't work at all with the headlights on, my left is sporadic at times,the hazards work completely fine for some reason and if I use my right signal without my headlights on it flashes every signal for some reason.
some of these are new but the cluster lighting up with the brakes has been a thing since I got it

ok so my hazards stay on with the parking lights apparently since I needed to use them I figured that out. also my right turn signal activates all the parking lights
my left front bulb doesn't work no matter what unless the parking lights are on and then it sometimes works, I have already put a known good flasher in and the turn signal switch seems to work perfectly fine but maybe I'm wrong.
definitely getting annoyed with this wiring

Maybe a bad ground somewhere.
Also check that the plugs in the bad of the cluster are seated properly.

The front parking light sockets are known to get water in them and rot off the ground tab.
I would check them first.

both sockets on the front have working ground tabs and were checked first. also front grounds by headlights were cleaned

I don't think that could cause a good majority of my issues from a dash light not seating properly since the parking lights being on or off has such a drastic effect

my cluster turn indicator lights stopped working awhile ago and came back last drive. same problem with my right signal and lighting up my entire parking light circuit so I'm gonna take that tail light off Saturday since I'm getting new ones to replace that one that is litterally cracked in half all the way through including the back plate

took everything apart and haven't found the issue yet... I'm not sure what's going on with the right side activating the parking lights throughout the whole vehicle and with those same parking lights on making my front left not turn on at all

I think you need to look up accurate wiring diagrams (factory service manual, dont trust Haynes or Chiltons) and start troubleshooting all of the wiring with a multimeter. Trace the problems backwards to a cause.
Inspect the wiring and connectors under the dash. There's also some major wiring junctions at the firewall and just rear of the battery.

Did this car ever have an aftermarket alarm system or remote start installed? Both cars I've experienced with those in their history were a nightmare.
Did it get stored for a very long time and possibly attacked by mice?

Some confusing things can happen with bad fusible links or fuses, but your symptoms are pretty wild.

Don't worry about an ECM swap or any other such things when the wiring is fubar.

Carter, listen to this man if not anyone else. Said it better than I could.
