2002 buick lesabre instrument panel lights dim. Dimmer switch has no effect. Dimmer was replaced.

This is more than likely an internal fault in the instrument cluster since the other lights stay bright and you can control them. I suspect that you may need to remove the cluster and have it rebuilt to cure this problem

Fortunately, the battery was still under warranty.

From what you have listed , door lock's instrument cluster , radio , HVAC - heating an A/C . An doing it intermittantly an starting to work again after slamming a door or the trunk , I would think a lose ground connection . Most likely in back of the instrument panel somewhere .To be sure , looking at a wiring diagram to see if these thing's share a common ground point . G-200 This would be my first place to look , because everthing that stop's working is grounded here
LH front lower corner of the passenger compartment on the LH front door pillar . You will probably need to remove the plastic kick panel . Do you know what i"m talking about . If not there have the vehicle checked for DTC'S - diagnostic trouble codes , BCM , IPC , HVAC control panel .
