Reverse Light Switch
 

My reverse lights are out. The fuse & bulbs are fine, so I'm assuming it is the reverse switch.
I found this DIY on Renntech for the 996: http://www.renntech.org/forums/tutorials/article/42-replacing-reverse-lightsback-up-lights-switch/

Does anyone know if the same procedure works for a manual 986?

Has anyone replaced the reverse switch before?

FYI, it looks like the correct part number for 98 manual trans is 996.606.133.00.
I just ordered one and will update this thread when I install it.

back up lights
 

I had same issue till today. Access to back up switch is from right side. A month ago I had major transmission work and I really did not pay attention tile few nights back that my buck-up lights do not operate. Close inspection of all fuses and bulbs tested OK. While inspecting buck-up light switch today I found out that connector from Buck-up switch is not connected and actually was dangling in transmission:eek: Some idiot during assembly did not attached connector.
I would suggest check all connectors and buck-up switch for contacts first, if that does not work pull switch completely and test the switch before you replace it.
I hope this helps.
