Default Electrical issue: parking lights on when they shouldn’t be!

Hi everyone..
I’m gradually sorting through all my (944S) issues.. but I seem to have created a new one.
When ignition switch is on and/or car running my right side parking lights are on. Everything else works as it should.. all lights ok, both L and R parking lights turn on when car is off and turn signal stalk switched L or R.
A couple things I’ve discovered with troubleshooting:
- The parking lights will stay on even when I pull 7.5amp fuse for R side parking lights
- The lights go out when I pull 30amp fuse for wiper motor
- when ignition off and I turn signal stalk to R the parking lights do come on and the wipers are powered

So, I’m getting power between wiper and R side parking lights.. but where?
Based on my limited knowledge I assume the most likely places the wires could be in contact is in the steering column and fuse box.
I’ve pulled the fuse box out and wiggled the wires hoping to locate the short but no joy.. I pulled the steering wheel and did the same with the wires in the column with the same result.
My next step is a more in-depth look at the fuse box and/or open up the steering column switches a little more.

Any one with more knowledge of the system shed some light on where I should focus my attention.. or known issues? Or maybe something obvious I missed?

The problem only started a couple weeks ago... around the same time I was removing a defunct alarm system. I can’t say for sure they are related but can’t rule it out either.. just more info for troubleshooting.

Thanks!

I had a similar issue. I found a short in the wiper/blinker unit on the steering column. Had a spare car and it to had melted in the same area. I just cut the wire that supplies 12v to the parking lights at the plug behind the dash. Not the best solution but I had smoke and melting. Don’t feel like re-wiring the whole car.

I agree- the only places those two come into proximity is the steering column assembly- what looks like parking lights is actually your blinker “stuck” on s
due to a short in the assembly. It has crossed to the wiper.

Buy a new-for-you (aka “used”) signal/wiper assembly.

Install it (don’t forget the small locking screw underneath the dash trim right behind the wheel. It’s a little PITA to get at. Inspect your wires before installing the new one. Or better yet, inspect the wires and see if the problem is just before where the wiper stalk assembly connects. Good luck!
