Lights not working well

i would check the fuses first, most of the time a fuse will control more then the label says

Check the radio fuse, The power window relay,and the accessory fuse, something shorted out the window circuit, if it keeps blowing fuses you will have to trace the harness for the short.

use a test light and check all the fuses in the fuse box.if all the fuses are good,its possible that the neutral switch may be bad causing no reverse lights.

No it's not a alternator problem , Instrument cluster problem .
Fixing PRNDL odometer LED not displaying on 2001 Buick Century

sounds like a fuse is blown.. not sure what fuse it is, but your owners manual should tell you exactly where its at.

this is a common problem and the dash cluster must be removed and sent out for repair, cost is about $175 to replace the LED (Light emitting diode) display that has burned out, this is a faxtory defect as far as this expert is concerned, it is not a fuse problem.

Good luck (remember rated this help).

I would check fuse in the fuse box on driver side.Should be a 15 amp fuse.

maybe but sounds like a couple of lights have burned out,. the owners manual should tell you where the fuse box is located. The dash light for the odometer/gear indicator may be accessible from under the dash, get an auto maintance repair manual from the local auto parts store , perfably a chiltons for about 20.00. It will help u loctae the dash lights and the fuse box more readily.
