Just bought a 1989 240! Rear brake lights don't work, and I'm confused about "rear fog lamps", I hit the switch and it seems like the left brake light comes on. The bulbs are fine and the fuse is fine as far as I can tell. Any help would be greatly appreciated! Thanks!
 
Clean up all the grounds. They tend to get corroded and cause weird electrical things. The brake light switch would be worth testing as well.
 
Bulb failure sensor could be bad

This was the issue on my 92 745. Inspection of brake area switch found all AOK.

Rear fogs = single lamp on sedans; you can convert a wagon to get dual rear fogS, when going aftermarket Estonia tails.
