2006 Le Sabre Buick fuse for reading lights, right tail light, and lights for heater keeps blowing. This has been rewired but keeps blowing.

If the fuse blows immediately, there is a short circuit to ground. If the fuse holds for a while, there is a overload in the circuit. I'm confused why the right tail light is on a circuit with reading lights and dash lights - that might be part of the problem.

reading light switch will nbot turn on lights, will turn lights for radio and heater lights on and off. lights for speed of fan and fan floor-defrost will not show. This has been rewired by a Chevy dealership that is highly rated. They did find a wire worn through replaced the assembley wrapped the wires to protect them and covered the culprit that worn the wire. get this when i pushed the key fob door open switch three times, now the right blinker is working agian but the interior items I list still are not working correctly. i have been told since i purchased this care that the 2006 lesabres are famouse for these issues.
