Driving the 6 miles home on the Interstate, the instrument panel shut down completely; no speed, tach, gauges, idiot lights, nada. The AC control also shut down.
About 600 yards from home, while going around a turn, suddenly everything came back on, but now the "service engine soon" indicator is lit.
Background: On Monday, after two ours of stop-and-go traffic coming home form the Beach, the car overheated. We cooled it down, topped off the coolant and went home without incident. Prior to rolling, a good samaritan mechanic type told us that the radiator fans were inoperative, but when we started the car and idled for a few minutes, the fans kicked on. Are the issues related? Dunno. What do you smart guys think?
Yes, the light on the A/C switch went dark and A/C stopped blowing cold. When we checked for a code, we got no reading. Weird.
Side note that may have bearing on the situation: we determinuined that there is an issue with the A/C switch that causes the A/C to shut down intermittently. Before yesterday we never had any issue with the instument panel. We've owned the car about 5 months. Previous owner made no mention of the issue (not that they would).
slosho, this the best set of diagrams I found on the Malibu. These are for a 1997, but applied to my 2002. My problem turned out to be the BCM. He's the link to the diagrams. http://mechdb.com/index.php/Chevrolet_Malibu.
