Trouble Shooting
WARNING: This page is about a different car, the 2000 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.
Ensure all ground connections are clean and tight. Check fuses, and replace as necessary. If fuses are blown, check for short to ground in power supply circuit. Visually inspect for broken or open wires. Check for a broken or partially broken wire inside insulation which could cause system malfunction but prove good in a continuity/voltage check with system disconnected. Ensure any aftermarket electronic equipment is properly installed.
