Question about 2001 Pontiac Grand Prix
I have a problem with whatever controls the Driver Information Center display, the automatic headlights/daytime headlights and fan motor control. Sometimes when I turn the fan on, the DIC display goes out, the automatic headlights go out and the fan no longer works. Or sometimes they don't work at all when you start the car but may come on later while driving. From reading various blogs it appears the problem might be with the multifunction switch. Does that seem right? And if so, is it the same as the turn signal switch or attached to the ignition switch? Or is it something different? I am having the same problem. The blower motor will just stop and the headlights will go out. After a while the blower will sometimes come back on and the headlights will come back on at the same time. I can manually turn on the headlights and they will stay on but the auto. lights go out when the blower quits. Sometimes the blower will only come back on if it is set on high. When it coomes on if you turn it to a lower speed it goes back out along with the headlights.
I had the exact same problem, I changed the "ignition switch" because the contacts inside were burned, this is why you see all those troubles coming in and out at different moments. It costed me 150$ to do it myself, buy the switch on an online reseller, must cheaper than the dealer! Now everything is back to normal on my Grand Prix GT 99 exept that my headlights don't light up automatically when starting the car... I have to check my fuse/relay and switch to make sure everything is ok on that side.
