Q: When I turn on my parking lights, my dash turn signal indicators light up. The lights still work properly, but I get shocked when I get out. When I take out the front indicator bulbs, the problem is solved, but I have no turn signals in the front. Please guide me to the solution.

Q: The air from the blower only comes out at the bottom vents (heater vents). I believe it has something to do with the vacuum but my GMC Owner's Manual(3 separate books) doesn't have a vacuum system diagram. Could you help me troubleshoot this problem before I rip-off the dash? Thanks
A: You need to locate the vacuum diagram......
All lines start and end at locations specified in the diagrams. The auto designers make it so you should not need to tear the dash apart..... Ed
