Wiring and electrical
Somebody installed a new stereo in my 02 Chevy
Avalanche now my stereo doesn't work my heater
doesn't work my RPM gauge doesn't work gas
gauge doesn't work my speedometer doesn't work
wondering what would have caused this problem
and there are no fuse is blown.
Somebody cut or disconnected some wires that they should not have.
On some GMs you can't remove the original radio. You have to push it back behind the dash, still connected, for certain things to still work. HTH. -Jim
