Thread: HELP!!! Heater affects 'Drivers Info Center' computer on 1997 GTP

I have a 1997 GTP. Usually when I turn on my heater (I don't have climate control), it works only on high and causes the 'Drivers Info Center' (DIC) to go off. Sometimes it goes so dim that it can hardly be read and sometimes it flashes. Every once in a while it will work normally and during these rare times, the DIC functions normally too.

I have replaced the resistor for the blower. I don't know what needs to be done to fix it. Any help would be greatly appreciated.

Thanks

From what I know, the fan speed selector, on the back of the switch there are resistors that control the speed of the fan. You said it was flashing and stuff like that, I would just replace it. Go to a junk yard and pick up a replacement.
