Porch light repair
This was on a 2002 U320, but the steps will be the same for other similar models

If you have problems with your porch light,the control box and relay are located inside (behind) the box next to the passenger seat, the one that holds a 110v plug, passenger side heater control, 12v outlet, slide cover switch and magazine rack. A new part and at least two hours labor (if you know where to look and know what you are doing) and you might be lucky to have 1/4 inch of wire to work with.
To do this you have to remove the various outlets on the box (just push them inside the box, AC vent knob, etc) … But the secret is that entire assembly, cup holders and all, slides straight up and off the mounting.
I know I looked at it for quite a while thinking you had to remove all those screws, but in the end there were just a few that needed to be removed and then presto the assembly slides straight up and out of the way. Look for screws that go from the solid wood box into the pine wall cleats.
Repair / Bypass
For all coaches with the “Touch Light Control” on the entry door assist handle, there exists the possibility that moisture can get into the grounding screw on that handle (The bottom screw in the lower base). This situation will cause the light to come on and stay on.
To correct this situation, remove the lower base and drill the lower bottom hole to accept a plastic wall anchor (Do not use a metal anchor). Next, seal and reinstall the lower base. This procedure will prevent moisture from grounding the control, thus allowing the light to come on.
NOTE The plastic wall anchors mentioned above are available at your local hardware stores and are used to hang pictures and attach other items to sheet-rock walls. Use a #10-14 plastic wall anchor for this procedure.
If you have added the plastic anchor at the base of the light and it continues to be too sensitive, you can open the control box and locate the resistor marked R8. This is a 39K resistor. Remove this resistor and install a 27K resistor in its place.
If you have to replace the module, you may be lucky and still find some new old stock. Look for intellitec touch light P/N 00-00098-000 … As of this writing https://rvpartsexpress.com/product/intellitec-touch-light-kit-00-00098-000/
