1999 Pontiac Grand Prix GT
3.8L
V6 3800
tech = JK
question = Initially the L.E.D went out on my radio but it still works,
Then the Driver information center stopped working, now my dual
climate A/C L.E.D
is flashing very fast in the morning but when I leave work it is out
completely. Suspect a bad module or two but I have no idea where they are
or if that is even the problem.
HELP, all kinds of electrical issues with this car.






JK:
Hello and welcome.
The radio light being out may be a faulty radio, but withe the other items  having
problems, they may all be related. Try moving the interior light  dimming switch
from low to full very quickly and several times. You may  have a headlight / interior
light dimmer switch problem. Also, be sure to  
check all fuses.
Another possibility is a faulty ignition switch. The ignition switch supplies  power to
many of the cars systems. This would not explain the radio  problem, but it may
explain the other 2 conditions. Cycling the ignition several times quickly back and
forth can sometimes indicate a faulty ignition switch.
