If it's doing this while the vehicle is running, it would be because the daytime running light system of the Grand Am included the instrument panel lights. Prior to the daylight sensor becoming standard, on some GM products, only the headlights were part of the daytime running lights system, while on others, it included all the lights.
Most dash lights have a setting knob to turn the dash lights on and off and to dim them, maybe this switch is off.
Which lights? what happens when they come on?
Probably the dash fuse is blown, or the dimmer switch for the dash lights is bad!
If all the dash warning lights are illuminated, you probably have more problems than not getting any heat. The only time all the warning lights come on at once is just before starting the engine, as a lamp check.
all other lights on car work ,just no dash lights,could it be a fuse?
If all the dash lights are out, it is the switch that is the problem.other wise, you have to remove all the lowre pannels to get at the bolts that hold the dash cluster in.
I have a 1991 Chevy surburan and it has no tail lights and no dash lights, all fuses are good
If parking and dash lights work: Maybe bad bulbs (double filamented) Bad socket? Bad ground circuit?
It's a 20 amp mini fuse #37 in the fuse panel under the hood on the passenger side fender well. It is labeled "Parking" in the fuse diagram, and if blown will cause you to have no dash lights and no rear running lights.
Headlight switch (IT) controls the dash lights ALSO.Some have a fuseable link..ASSUMEING all the bulbs are g00d..
If all the dash lights are out then there is two causes for this. The first is all the fuses have blown the other is the relay for the dashboard lights has went out.
It is risky fooling with the dash lights as the circuits can be damaged with static electricity. I suggest taking to a garage. How ever, you can get a static electricity band to prevent that from happening. Most parts stores, such as Autozone, Advanced Auto Parts and O'Reillys all have the bulbs for you dash indicator lights and a good book like a Chiltons will tell you how to remove the dash.
