my speedometer doesn't work what should i do also my back lights wont work any suggestions

 

not so sure for the 91 model but for my 82 camaro i would checked the fuses on the fuse box one little fuse can make a lot of things work

 

Welcome to TGO. CamaroRS your speedo is electronic. You might check the VSS--and certainly do a search as your problem is common. 82lg4, yours is mechanical so a fuse won't do the trick.

I had a 91RS, speedo quit working. turned out to be the speed sensor. not an expensive part and it's attached to the tranny in a easy enough place to get to.

 

I have the same problem. Except for a while it would sporatically just start working. The question I have is I look up speed sensor and two thing show up a sensor that goes in the tranny and one that bolts on like a connector. My brother and I changed the sensor in the tranny. It stopped working at all. I have a 1991 Camaro RS 5.0 305 tbi. Any Ideas
