Hello Lorex you mean to say Infrared Illuminator?If yes then you can watch this video might be it will help you to repair your Illuminator device.https://www.youtube.com/watch?v=SI7_zXGJCgY

Maybe the wires in switch assembly dirty or loose, try spraying with wd40. Also the headlight works off engine power maybe it's battery at fault.

Check for power to the light switch. If no power, trace wiring from fuse panel to switch. If there is power, then it could be your switch that is bad.

Hi Kacey, The first thing to do is determine where you want it. Once you have, drill the relevant holes and then identify the cable which will carry the power and that which will operate the illumination. The center connection on the lighter is the main power which should carry an in line fuse. this can be a constant live or an ignition switched connection. Identy with a test light with one wire connected to ground and the other used to identify the cable. The cable connection for the illumination should be identified in a similar way using the test bulb. This can be done by following the cables leading to one of the interior units illuminated when the the lights are switched on. Make sure you have the correct cable by operating the light switch. If the test bulb operates with the switch you have the correct cable. Lastly connect a cable to ground and light up all you want. Regards John

Power is supplied to the instrument illumination by the "TAIL/ILLUM LIGHT" fuse, Fuse #4 (15 Amp) located in the dash fuse block under the left side of the dash. This fuse provides power for both the primary and secondary sides of the TAIL LIGHT relay. The Combination (Headlamp) switch provides a ground path for the primary circuit of the TAIL LIGHT relay. When the primary circuit is completed by the Combination switch, the secondary contacts close and provide power to the tail lamps as well as to all of the instrument illumination bulbs. The ground for the instrument illumination bulbs is a variable-resistance circuit which is controlled by the illumination controller. The final ground for both the combination switch and the illumination controller is Ground G302, located under the center console.

Hi, make sure the cutters are not jammed with paper. To reset turn the unit to reverse for 2 seconds then auto then off. Allow to cool for 25 minutes then retry. Also make sure the base is locked in properly. Hope this helps, regards Phil.

Verify the alimentation (power supply) parts,and the mechanical part gears.I thing onesome gears is blocated.

Here is repair information from Mitchells:
1) Disconnect power mirror switch connector. Connect test light between power mirror switch harness connector terminal "A" (orange wire) and ground. If test light illuminates, go to the next step. If test light does not illuminate, repair open in orange wire between power mirror switch and righ rear power distribution center fuse block No. 1 (located under left side of rear seat).
2) Connect test light between power mirror switch harness connector terminals "A" (orange wire) and "J" (Black wire). If test light illuminates, check for poor connections at the power mirror switch. If connections are okay, replace power mirror switch. If test light does not illuminate, repair open in Black wire between power mirror switch and ground.

Your Power steering pump may be loose. This may be reason for the belt shredding and will make the new belt shred too pretty soon.
