No reverse (backup) lights

[rendos]

I have a 95 yukon that has no backup lights. I replaced the fuse and bulbs. Still nothing. What do I check next?

clean bulb sockets with some 800 grit sandpaper.

switch unit on left side of tranny with the shift linkage going thru it.

Yeah probably the unit sunlit mentioned, I had mine come out of alignment before.

The easiest way to tell, does your truck start in "N"??

Could be the circuit board that the bulbs/sockets attach to. I've had 3 or 4 that have crapped out over the years and the reverse light socket is always the one that fails.

 

[rendos]

Yes. It is in reverse in 'N' and neutral in 'D' and drive in '3'.

I replaced the board the bulbs attach to already. No change.

your gear indicator indicates those readings? chuck it for a new delco one if adjusting it does not help.

Sunlitcomet - wow. Thanks for the detailed instructions. I will do this hopefully this weekend.

 

[rendos]

Worked perfect. Thanks for the help.
