The driver information center on my 97 Grand Prix is intermitent - some times it's just fine, other times it's blandk - when it's blank, the heater fan doesn't work - I think I can hear a click down by my left ankle when it goes from ok to blank and back, like a relay switching - Any ideas would be appreciated - Also, any idea where I can down load a wiring diagram for the car - Thanks

When the DIC acts up along with HVAC blower problems, the cause is normally an ignition switch and harness assembly with carboned up contacts.
