Poncho, sounds like you know what you're talking about... Thanks for sharing this very useful information about the resistors... I am taking the task on this weekend to add the resistors to my 02 Impala. I have had this problem I'll bet for a couple 2, 3 years. Every summer it seems like for the past 3 years my wife would call me and say the car wouldn't start, I had no clue until recently reading these posts. Needless to say it has gotten way worse, and heat and humidity in my opinion do very much have an affect on this problem. I was reading the earlier post and tried cutting the yellow wire, splicing in the toggle switch. This has worked fine for about the last 2 months, but the wife got locked up this week at the doctors office. It was 90 degrees and super humid. I went to pick her up, car had no dome light, no radio display at all, no air (sweating bullets). What I did was unhooked the battery for 5 minutes, hooked it back up, car started, still no air, no dome light, and no radio, display read "LOCKED". Well, I drove it back to work to finish the day, and same thing happened again, I had to unhook the battery just to get it going to get home. I planned on taking it to the dealer this morning, car did not start, had to unhook the battery, then it started, only the weather has cooled right off to around 65 and rainy. So I now have a cleared computer with no issues at all. I can't take that to the dealer because they won't be able to tell what is wrong with no light on. I was lucky enough to find this thread I guess, I'm going to give her one last shot with your resistor method this weekend. I was just about ready to go buy the ignition switch and change it out. Do you recomend that I still change the ignition swith? Or will I be okay if I follow your instructions with the resistor method? Thanks again for all the useful info...
