Im 2nd owner95 Merc grand Marq was missing signal brake fuse when got it home cyclops brake light works,,?
62K miles one owner no signals fuse missing, no brake lights ,Lights work when the headlamps turned on cyclops brake light works! bought new round fuse or relay and junk yard fuse still no joy can you help?
This is puzzling. I think this is before the years with the LCM lighting control module. Do the turn signals work? Did the missing fuse blow when you put in a new one? Someone took it out for a reason. Could be an actual short, maybe at the brake light sockets. Check 'em for corrosion.
The car kept inside so doubt if any corosion on light bulb sockets. The point of LCM...1995 so I dont know. 1 owner clean clean62K The radio will not punch off as I punched it on,,have to turn down Volume,,The taillights work when headlight are on but no brake lights but cyclops does work,NO SIGNALS..at all. The signal flasher was removed under dash when I got car home 1 st time and did not blow when put new in? Thanks so much
We have to find out if your car has a LCM(they go bad and cause all kinds of problems, there was a recall). I've been doing auto electrical for many decades, and I'm still baffled. One possibility is the turn signal switch, stop lights go through it, it's not working, prime suspect. I think you have to pull the steering wheel, not so much fun with airbags.
