no reverse lights... 83SD
 

new bulbs, replaced all fuses. NSS works great, I'm guessing there is a reverse switch in the shifter somewhere... clue?

My NSS is bad as far as starting in Park goes.

My understanding is the NSS has (2) switches in it.

One for Starting Function
One for Reverse light Function

ie my Back up lites are fine but starting in Park is starting to get iffy

I don't know if there is another switch or not in console.

What I'm saying here is eventhough your car starts OK in Park and all that does mean the other half of switch is ok.

Hope this is helpful somehow.

doesn't not does. I need to proof read more, sorry.
