Fuse... or the multi-function switch on the left side of the trans.

Is the switch easy to repair?

Tough to remove from the transmission, and when you re-install it, it has to be "clocked" to it's original position or it won't communicate in sync with what gear the transmission is actually placed in by the shift lever.

There are rivets in the top that you drill out. Then you remove the lid. Inside are brass contacts that get all gunky with dried grease and corrosion. These can be cleaned and regreased.

I think new they are about $400?

You can tell you have a bad switch if your right mirror doesn't dip, and at the same time, your reverse lights don't come on.

my reverse lights were from cracked wires in the hatch, contrary to populat belief

^^Good call, forgot about the broken wires in the hatch hinge area.

...cleaning should be eazy though.

very usefull! Thanks!

There may be others I will search.

However, if there is a chance of missmatching during instalation I would prefer not to touch anything. Now at least everything else seems working.
My problem is that I may need the reverse light for the inspection which is due in 3 months. I am not sure if they check reverse light in NJ, but if they do they probably won't let me pass...

That's a great tip! I will try it.
Thanks austinado!

I will check again the cable and bulbs. However if I move the cable the light doesn't turn on. Also both lights appear at the same time when it works - so can't be bulbs or oxidized contacts on one of them...

So if you have the right mirror working 100% of the time, and the reverse lights aren't working, you probably have a break in the wiring where the wiring flexes with the trunk hinges.

issue with a B4 years ago. The reason why I think on my Audi 100 it is not the cable or at least this section of the cable is that once when the reverse light came on (it does once every 50 times may be, I can of cource notice only when it is dark), while in reverse I pulled the parking brake, opened the trunk and started moving and twisting the cable. However it didn't turn off even for a moment, and it is only the reverse light that I am having trouble with.

I will check all the wiring below the covers. Hopefully I will find something there...

Thank you for your advices Austinado!
