1. Rear Window Switch: Check the rear window switch. If it is faulty, it may prevent the rear window from opening. Try operating the switch multiple times and see if it makes any difference.
2. Power Window Motor: The power window motor for the rear window may have failed. Check for any unusual sounds or grinding noises when operating the switch. If the motor is faulty, it will need to be replaced.
3. Wiring Issues: There may be a problem with the wiring that connects the rear window switch to the power window motor. Check for any loose connections or damaged wires.
4. Door Jamb Switch: The door jamb switch, also known as the courtesy switch, may be faulty. This switch controls the dome lights and other accessories. Check the switch for proper function and replace it if necessary.
5. Fuse Box: Double-check the fuse box to ensure that all the fuses related to the dome lights, lighter, and electric side mirrors are intact and properly seated. Sometimes a fuse can appear to be good but may still be faulty.
6. Electrical System Issues: If you have confirmed that the fuses are good, the problem could be deeper within the vehicle's electrical system. This may require further diagnosis by a qualified mechanic or electrician.
It is recommended to consult a professional mechanic or auto electrician to accurately diagnose and resolve the issues you are experiencing with your 1996 Chevy Blazer's rear window, dome lights, lighter, and electric side mirrors.
