Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hi there, I am Cam. Did you add a new radio as in aftermarket to your Suburban?
Did it require you changing any wiring? A common issue is the orange wires being connected together. One orange at the radio is power and the other is a data line. Connecting them disables the dateline and causes this sort of issue.
Ok do things like the windows on opposite sides work, the heater turn on?
Is the check engine light on?
Ok, at the ignition switch, do both thick red wires have power?
