I have a 1994 Grand Am and the dome lights won't shut off until the battery saver turns them off. They are on continually while driving. I've replaced the dome light switch but don't know where else to look. There are no visible switches in the doors.

Principles of Operation
Interior Lighting The interior lighting is broken down into two groups: the courtesy lamps and the illuminated entry lamps. Both lighting features interact with the courtesy light arbitrator. The battery saver is also listed in this section.
Courtesy Lighting The courtesy lamps consist of the dome lamp and/or map lights. The courtesy lamps can be activated by the GEM using the panel dimmer switch, or by any ajar door. The courtesy lamps will shut off when the doors are closed and the illuminated entry feature is not active, or when the vehicle speed is greater than 8 kph (5 mph). The interior lamps will not be reactivated until the vehicle speed is less than 5 kph (3 mph) and a new door open warning lamp switch signal is received. The inputs are:

• ignition switch position

• driver door ajar switch

• front passenger door ajar switch

• rear left door ajar switch

• rear right door ajar switch

• vehicle speed switch (VSS)

The outputs are:

• battery saver relay

• interior lamp relay

Check to make sure someone didn't brighten the dash lights all the way up to the point they turned the dome lights on. Or the interior light switch has been switched to always on.

one of your door switches is bad or not making contact with the door frame

The gas u put I'm the tank was high octain if it was it was making the engine fire to early replace the gas and it should wor properly

if you have theft security problems if you jump start the vechicle it still wont crank.have battery load tested and checked battery could be weak.your current drain can be caused by many things, like radio,faulty power lock, dome light remain on,faulty pcm,faulty alternator,faulty heater blower motor relay.

the fuse will say ctsy lamp, however your problem is a door switch that is either stuck or shorted out, ( the little plunger in each door,, check all of those to see if they are shorted,, you can remove them,, use a meter to check them with it set on continuity , put a test lead on each end,, and ground to the case , with the plunger out, you should get continuity , with it in you should get none

YOU MAY HAVE A BAD DOOR AJAR SWITCH. HOWEVER, YO HAVE A TIMER THAT SHUTS OFF THE INTERIOR LIGHTS AFTER 300 MINUTES. IT'S CALLED A BATTERY SAVER FEATURE. TEST IT OUT.

THE EXTENDED CRANK MAY BE A CHECK VALVE IN THE FUEL PUMP IN THE TANK, ALLOWING PRESSURE TO DROP WHEN YOU TURN THE ENGINE OFF.
OR A BAD FUEL PRESSURE REGULATOR ON THE ENGIEN FUEL RAIL.

TRY THIS TEST, TURN KEY TO "ON" POSITION, WAIT 5 SECONDS, SHUT OFF KEY FOR 30 SECONDS. TURN KEY ON, WAIT 5 SECONDS, THEN START ENGINE. IF IT STARTS RIGHT UP, YOU ARE LOSING FUEL PRESSURE WITH ENGINE OFF.

THIS BUILDS UP PRESSURE IF IT DROPPED DURING SHUT DOWN.
REPORT TEST RESULTS.

PLEAE RATE, THANKS

There should be a switch or rotary dial on the dash to shut off. If it continues to stay on its most likely a faulty door jamb switch. Inside each door there is a little plunger type switch which closes when the door is closed. However it closes a contact when the door opens completing a circuit to the interior lights. If one of the switches is corroded or shorted (meaning the wire is touching metal or internally shorted in the switch) the lights will stay on. You will need to remove each switch separately and disconnect, when the lights go off thats the bad switch.

I found a paritally blown fuse. When the fuse blew metal pieces ended up partially making contact. After replacing the fuse everything worked great.
