1. Blown fuse: Check the fuse that powers the dash lights, climate control, and shifter light. If the fuse is blown, replace it with a new fuse of the same amperage.
2. Faulty switch: The dash light switch may be faulty. Try turning the dash light switch on and off several times to see if it makes a difference. If the switch is faulty, it will need to be replaced.
3. Wiring issue: There may be a wiring issue that is preventing the dash lights, climate control, and shifter light from coming on. Check the wiring connections to the dash light switch, climate control, and shifter light to make sure they are secure. If any of the connections are loose, reconnect them.
4. Faulty instrument cluster: The instrument cluster may be faulty. If the instrument cluster is faulty, it will need to be replaced.
If you are not comfortable troubleshooting electrical issues, you should take your car to a qualified mechanic for diagnosis and repair.
