While I'm personally unaware of any crashes or people dying due to this problem on this model, GM has a well documented history of bad ignition switches on other models that are not included in the recall that they have known about for many years. The effects of the bad ignition switch with this model are: 1. the A/C - heater fan blower works intermittently, if you're lucky, and then only on high speed if it does. None of the other speeds work at all. 2. when you try to turn the fan motor on to run the heater or A/C, the headlights go out. While there are different schools of thought on the cause, after researching the internet, one component seemed to correct the problem every time. You must replace the ignition switch. The problem is not the resistor as some seem to think, but the ignition switch. Those who replaced the resistor always had to come back and replace the ignition switch. Those who replaced the ignition switch had fewer, if any, problems after that. I write this to you because I believe someone "up there" needs to know this information. I simply hope it doesn't fall on deaf ears like most things. I withhold further comment. Regards, [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2003 Pontiac Grand Prix. The contact stated that the rear tail light failed to provide the proper illumination when the brake was engaged. The tail light housing retained moisture and caused the tail light lens to fail. The vehicle was not repaired. The manufacturer was made aware of the failure. Updated 04/30/13

When I turn on the blower switch, the blower doesn't work and the headlights go out. It mainly happens on the lower speeds but occasionally happens on high speed also. It is intermittent but happens around 75% of the time. This has been going on for about a year. I have checked all fuses and relays that seem to be related and find no problems there.
