Check fuses
It would be best to have a certified technician look at that as it can be quite complicated.
2000 Malibu has one on left dash fuse box and one on right end of dash panel.
Should be the same fuse for parking/tailights
CHECK THE FUSE PANEL DASH & TAIL LIGHTS WORK FROM SAME FUSE
Where is the Dash board lights fuse of ford mondeo 2002 lx
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.
check your fuses, your owners manual will tell you the location of the fuse.
Should be parking/tail/dash lights
The fuse is blown. They put the dash lights and tail lights on the same fuse so that if you are driving at night the absence of the dash lights will be made relevent to you in order to get your tail lights fixed.
Have you checked the dimmer? I have a 2000 and there is a wheel to dim the dash lights to the left of the steering wheel, just above the cup holder.
The rheostat for dimming and brightening the dash lights.
