Howdy,
I have a 1995 940 Wagon who is still running like a champ, but I got pulled over today because my running lights are not working when I'm moving/idling. Both blinkers work, hazards work, and when I press on my brakes, my left brake light comes on (right bulb needs replaced) but when I'm not pressing on the breaks or using blinkers there's no light whatsoever coming from the back tails. They're turned on in the cab, the fuses are good, and the bulbs are good. What would cause both sides' running lights to not work but still let blinkers/hazards etc run fine?

Anything helps...

 

So I put a new bulb on that right tail light. My right running light is now working, but still only the left brake light lights up. When I push the breaks the right running light doesn't change intensity at all, but the left brake light works fine still.

 

i have had success in getting lights working by coating every connection (including connector plugs etc) that i could with dielectric
grease.

 

Maybe the bulb holders need replaced, I'm dealing with this now, the turn signals all use a dual filament bulb front and back, 21/5 w, the other 3 says ba 15s 21w/32cp on back of owners manual says 1156 but the two tabs on each side of bulb are one high one low in order to get them in. Could be just bulb holders are corroded a little ?
