GAUGE PROBLEMS

(1999 Chevrolet Malibu)
Visitor, 1999 Chevrolet Malibu, 265,000 mi


Turning the key to the on position the gauges would sometimes act if they lost power. When attempting to start the engine when the gauges were in this unpowered state, the starter would turn but the there would be no spark coming from the coil packs. I tested the lead and ground to the coil packs and the crankshaft position sensor. Since other components still have power (lights, radio, windows, etc.) the problem seems to be after the battery but before the coil pack which leads to the conclusion of it being something with the ignition switch or wires in between. No confirmed solution as of yet

Your problem is most likely a failing ignition switch. When turning the ignition switch to the run position and the instruments are inoperative, remove the fuse panel cover to the left of the instrument panel. The driver's door will need to be open to access the cover. Check for 12 volt power at fuse "H" (powertrain control module) and fuse "K" (Body Function Control Module/Cluster) with a 12V test light. If both these fuses are good and are unpowered (test light does not light) with the ignition switch in the run position, the ignition switch is failed. It is also best to replace the ignition switch if this is an intermittent problem as the instrument cluster and both the body control module and powertrain control modules must be powered for the engine to run.
