#27 of 28 2002 Pontiac Bonneville Info Center goes blank, defrost comes on
Oct 09, 2010 (4:06 pm)
3 times in the last month, while I am driving, without having the A/C on, the info center of the A/C panel will go blank (dark) and the defrost turns on. After it has been shut off for a while, I can start it back up and it works fine, but if you try to start it shortly after it happened, it remains dark. 2 of the times I had driven it for about 3 hours, but the last time was only 20 minutes. I thought it happened when I turned a corner, but am not sure of that. Any clue what could be the matter with this and how much moola we are talking about for someone (probably dealer) to repair?

what is the part i need to replace? I have a 2001 pontiac bonneville sle w/ 114,000 miles. The problem is the electronic heater controls turn off and on whille driving intermittently.
The heater temp display screen will turn black and you can't use any buttons while this is happening the blower turns on high in defrost mode(with a black screen still and no function of buttons). I replaced the blower resistor and the whole display screen/unit still no fix?
