2000 Malibu dash light & tail light not working; service vehicle soon light on

Possible charging system problem causing low voltage. Have the charging system/alternator tested for proper operation..If charging system operating properly, possible ignition switch getting bad. You can gently rock the key back and forth with the vehicle running to see if everything begins working again. If so, the ignition switch needs replacement

You only need to change the tail light fuse if it is blown. If you haven't checked it already, do that. Those stop/tail bulbs are 2 filament bulbs. One filament is for brake lights, and other filament is for the tail lights. So it is possible to have brake lights and no tails, if the filaments for the tail lights are burned out. But of course, it is unlikely that all the tail lights would be out and all the brake lights still work.

You may need a voltmeter to help solve the problem. It could be a problem in the headlight switch (a problem with the park light function), but is more likely a problem with the Lighting Control Module- or the Body Control Module-whichever your car is equipped with. GM first came out with the LCM, and a year or two later came out with the BCM. Both are mini-computers to control lighting and cabin functions. You would have to use a voltmeter and check things like power in and power out at the BCM of the park lights. You would thus need a wiring diagram to go along with the voltmeter. Those modules are located up under the dash-you can use google to see pictures of them, and maybe find locations.

the issue you are having has to do with the ignition switch harness, it is inferior in this vehicle, the best way to I have found to repair these electrical and fuel pump issues , is splice in a ignition switch wiring harness from a 98 - 03 grand am ignition switch harness, I have used Malibu parts also but they seem to be only slightly better than alero, I have done several of these aleros without come backs so there ya go ,

you put the light in wrong or wrong bulb. take a look again. go to a parts store to have codes checked for free

Hello: Check and see if the tail lights are working, if the tail light fuse is open the dash lights will not work. Also make sure the switch that controls the intensity is in the proper position.

The Tail lights and Instrument lights are usually on the same circuit so both will go out if the fuse for the circuit blows. Check for a blown fuse for this circuit and replace if out. If fuse continues to fail, check the tail light or side globes for a faulty globe and replace if necessary. Also check for any chafed wires that could be shorting to the body causing the fuse to blow.

dash and tail light are on the same fuse, if you lose your dash lights most people will check for the cause due to no speedometer, did you use a wiring kit for your application,

its easy to fix, when u open every thing there is four resistance in the back of the isnstrumen these resistance need to replace. maybe not four of them just what u need u can tell wich one need to replace. u dont need to buy 500 u can do it at home

Ignition switch is a solid culprit. the contacts get worn out or even "stretched " due to "Forced" turning of the key. You know the part where you try to turn the key past the stop point.

next time it does that move the ignition kee so you pry the swicht i had that problem its ignition switch that defect the housing swicht the problem cheers pierre
