Just recently my 2002 GTP started to show a blank screen on my trip computer and at the same time my HVAC system is dead. After driving for a few minutes, both the trip computer and the HVAC system would kick in. Both would then continue working. One time when this happened my fan switch was on full so the air conditioner started up at full blast when it kicked on. When I turned the switch back to low, the whole system, including the trip computer, went out again. All other instruments as well as the radio continued to work. A few miles down the road, both of them kicked on again.
Can anyone tell me what the problem might be?
