Back Up Light Failure
 

After this 09 blizzard, i was cleaning car off and my dad noticed that the backup lights werent working. Could that be a wiring problem or perhaps light bulbs?

its a 87 325e

Could be. Also check fuses, maybe a relay. I'm not sure, but there might be a backup light switch on the case of the transmission, obviously activated when reverse is selected, which could have been affected by the storm.

weather changes with moisture usually cause poor contacts with the bulbs, though it may be coincidence an it's a fuse or the backup switch :tup

hi i have same problem on my e46,ive replaced the fuses+ the reverse light switch, still they do not work ,can any1 help plzzzzz.

First get a multimeter and see if you are getting power from the contacts for the light bulb. Sometimes the bulb may look good but isn't, or there may be a short in your light assemble that has lost ground

I have had this problem with some older Mercedes
