1993 Lumina Sedan
 

Hi All,

I have a 93 lummy euro sedan with the 3.1 (great engine)

My latest thing, is some random electrical stuff - Temp gauge will bounce all over the place quickly, the power locks and dome light now don't work, and the radio randomly has power issues...

Im thinking it's a section of the wiring harness that must be starting to fail... I really dont want to replace the entire harness at $600, but does anyone know where to look to see if I have the beginnings of cracked, bare wire?

Thanks ;)

Maybe examine the fuses make sure they are all tight.

Do you have after market alarm? Those usually eventually screw with the electrical system.

Check the connection at the computer.
