Question about 1999 GMC Suburban

1 Answer

1999 Suburban 2500 4WD interior lights won't go off and no daytime dash light. Dome over ride button doesn't affect it. Had to remove bulbs. Have had panel lights sometimes off. Come back on after restart of engine. The temerature display in the rear view mirror drops to "32/ ice" when the temperature cools into the 40's. Loose connection? Computer?

Sounds to me like your light switch is faulty, however, check and remove all the door buttons to determine this, ensure that the wire/s are connected on the buttons and that the door is butting against them when closing.{ including the tail gate} Good luck

2000 Chrysler Neon interior lights wont turn on.


Time delay relay is the relay that allows the interior dome light to remain on for a brief time when you enter or leave the car.Usually the lights will remain on for a few minutes and then dim down and finally off.

It sounds like the daytime running lights were put on that circuit and the relay removed to keep them on constantly.
This sounds like a time and material repair that a shop will have to do. Tracing the wiring installed by the previous owner may be required to find out what was done.

I have a 2005 GMC Sierra 1500 Z-71 - the interior dome light works with the dash switches, but won't work when the door opens. Why?


Is there a button by the headlight control switch? I recently found out that the dome light only comes on while the doors are open when this button is engaged

Head light problems sometimes they will not shut off sometimes they (low beams) come on by themself high beam will not shut off


Are you sure there not running in daytime running light, when you think high beams are on

Also, there is sensor on the dash, usally on the speaker grate, that senses night and day. In the daytime your headlights will automatically come on when your car is in drive, and be on the high beam bulb, but dimmer than regular. At night, or in low light conditions, your lights will automatically switch from daytime lights to regular low beams. And yes, even when your switch on the dashis turned off, your lights work automatically.

To turn of the auto setting, just push the override button for your dome light, in and out 3 times, you should hear a chime, and your lights should shut off. This setting resets everytime you shut your vehicle off. Or to turn the auto setting back on, push the over ride button 3 more times.

2005 chevy suburban- my back-up lights and interior dome lights do not work. All fuses appear intact? Suggestions?


you bcm (body control module is bad) to have the dealer replace it will run you about $400. a quick fix for the reverse light is to splice 2 wires into the wire for the center plug in your trailer wiring. now run a wire up to each reverse light, cut the green wire to each reverse light and **** conect them up. this is a seperate revers feed than the one from the bcm. the dome lights remove the light cover on the second set of interior lights (the one between the drivers seats). the two side bulbs are map lights the center bulb is for the dome lights. run a jumper wire from the right or leftside socket to the center socket. you dome lights will now turn on with just the use of that switch i replaced the back bulbs with led's soo there is no extra amp's being drawn. you could bypass the bcm but i could not find any wiring diagrams for it and i dont know if it can take the added amp's

Dome light on my 1998 gmc suburban wont shut off


Maybe your door switch button has broken off. Sometimes I bump my dash light dimmer wheel (which also turns on my dome light) and it stays on in my 93 Chevy pickup

Inside door lights stay on after engine is turned off


Check all doors for a sticking door open sense switch. Check all over-riding interior light activation switches are off. If all the above are ok, check for a sticking interior light relay.

1999 Mercury Sable Dome Light won't shut off


Check the dash light dimmer switch. Perhaps it's set to have the interior lights on, when you turn the dash lights all the way bright, turning it a little more turns the interior lights on. Let us know how you make out.
