Default Parking Brake Light and ABS Lights Stay On
I have a 1993 w250 with a 12v Cummins in it. My parking brake light and abs light are staying on at all times, even after I mess with the parking brake switch and engage them disengage the parking brake. I figured these could have something to do with each other since the parking works just fine. My 4x4 light stays on all the time as well, even when not in 4wd, And I have made sure I am not in 4wd (I had a friend watch the front driveshaft). So if anyone has any ideas about either of those, I would greatly appreciate it!

unplug the abs module behind the glove box and it should shut off the brake relate lights. the 4x4 one could be a be a bad switch

What could be the issue behind the abs and parking brake lights though?

2 or 4 wheel abs? If you just have rear wheel abs, the sensor on top of the diff is the usual culprit.

I believe it’s only rear wheel, I’ll take a look at that when I get home tonight
