My 2000 Jeep Grand Cherokee Laredo has some electrical issue. First the windows are stuck in up position. The switches don’t work right. The left switches changed, center interior light stays on when vehicle in motion. And the information box overhead don’t work. All other gauges work fine.
Power windows use one fuse #12, 50Amp to power them. Check for power going tot he switch. If no power is going to switch check the fuse and power at the fuse. If the fuse is good and power is found, look at the wiring harness. Most common place for break in wiring harness is at the door jam where the door is opened and closed often.
The dome light is turned on with the multi-function switch. Make sure it isn’t turned on first. Then the light is turned on as a courtesy when the door is opened. If the BCM – Body Control Module thinks the door is open still the light will remain on. This can be from a failing door latch switch or the wiring harness as described above.
As for the overhead Vehicle Information Center, there are two fuses to check. Check #8, 15 amp and #22, 10 amp fuses.
