just bought 1990 cherokee and the back up lights dont work. Checked bulbs and fuses appear to be good. Any suggestions?

 

I have heard a bad or faulty NSS can cause this.

 

nss is neutral safety switch correct.

 

correct. there are a number of write up on how to remove and clean it yourself. Worth a shot I think

 

thanks appreciate it

 

Here's a complete NSS write up...

Hope it helps you..

 

My 90's didn't work aether.
On the same fuse is your trailer lights if you have a towing package, and the power for the transmissions comfort power switch.
In my case the trailer light pig tail was shorting together.
The transmission was real happy after that there is a amber light in the switch is it on?

 

First I would check for power with a volt meter. If your getting pos. voltage, then it's the grounds. If not work your way back.

 

I read that write up just now and it seems like it turned out well. My reverse lights don't always kick on right away, but they do work. Do you think that I may have to clean/repair the switch? Or like they say, if it ain't broken, don't fix it?
