I'm having issues with the right side rear lamps on my 1992 945T. Currently all lights remain dark on that side. Bulb out indicator lights at all times when parking or headlights are on. It illuminates (blinks) along with right turn signal operation and the transmission light in the console also blinks along with them.

I replaced a burned out fuse which restored the front right parking (yellow) light but didn't affect the rear. All of the other fuses involved with lights appeared fine.

The driver's side rear bulbs seem to work properly except for the backup light which does not illuminate. All bulbs have been examined and found OK but not tested for continuity yet.

On the right side, the two connectors on the bottom (tail light and brake light) bulb holder socket are loose and tend to fall or vibrate out. These fit into plastic slots in the lens assembly and form the contact surfaces with longer metal tabs.

The question is which one goes where? One has a yellow wire and one has a brown and white wire. The two locations for these are 1. vertical on the right (outside) side and 2. horizontal along the bottom of the socket. This is the socket with the dual filament bulb.

I note that unlike my 240's this side does not have a white colored socket on that side.


Any advice before I try again is appreciated. I suspect the bulb failure relay is involved as I have replaced two other relays this year already.
