Electrical problem
2002 Buick Regal 6 cyl Front Wheel Drive Automatic 80000 miles

Once in a while when I start the engine, the heater fan, rear window defroster, air conditioner, and cruise control, won't work.

All other elec equipment works fine. Then after a few minutes, it all come back on and works normal.

I suspect a relay but, haven't been able to associate all the problem electrical devices to one relay.

I have had some luck, restarting the car a few times, and this sometimes brings back the non working items.

what do you think is wrong?

Those 3 items all get their power from an orange wire coming out of the ignition switch.

A red wire goes into the switch and branches off in two circuits, a brown wire and a orange wire.

Next time it happens, try your wipers (which is on the brown wire) it they work, then I suspect the ignition switch is the problem.

Was this
