Default No Back-up Lights

Suddenly no backup lights on '91 ZR-1. Checked bulbs and fuse, both look good. Is the next most likely culprit the backup switch mounted on the transmission?

That would be the culprit. Pain to get to as well. You are headed in the right direction.

When my back-up lights quit, I went down the same road as you. I finally pulled the connector off the switch at the trans and jumped the connector. Bingo they came on...replaced switch. All fine now.

Goodluck.

Ditto. Switch cost me $23 at the dealers.

You're going to love fixing that.

I ended up taking the clutch slave cylinder out to reach it and even then its almost impossible to get a wrench on the little bugger.

While you're in the neighborhood, take care of the CAGS if you haven't already.

Randall.....

I had the same thing happen several months ago.. it is the back-up switch. I have a picture of the culprit on my webpage under "Other mods/info"... that's what you have to replace.......the clutch cyl is in the way, but it's a 1/2 hour job for a good mechanic at most.

Well you all were right, sort of. I managed to pull the connector off and jump the wires and WA LA the back-up lights came on. I put the connector back on the switch because I couldn't get the switch off due to it's tight location and my lack of a lift. The back-up lights started working! :D

For one day. :cuss

Will give it another try when I can get it on a lift or get access to the switch.
