93 caravan sliding door switch problem

[onebadmust]

Does anyone know how the sliding door switch works. I have the notorius problem with it causing the interior lights and bell to go off, very annoying to the wife. Iknow how a typical switch works but there are 2 spring loaded posts on the end of the door and 2 circular metal reciever pads where the posts come in contact. I have cleaned all of them real good with a scotch pad. I tried putting something behind the plastic holding the pins to kind of jack it out to make up any gap that may be causing the problem, but neither helped. If you help push the door and hold it to the jam then all is good, but as soon as you release the door, the problem comes back. Why are there 2 pins and not just the one? Also what is the big screw/ post with a coned shaped head with a screw driver slot in it on the end of the door just below the spring loaded switch pins.? It looks as if it fits into a cup with rubber around it. What does this do, is it some kind of switch or just a door guide? I (and my wife) would appreciate anyone's help. Thanks and sorry this was so long!

the button switch towards the rear is the "door ajar" switch and the switch forward is the "interior light" switch. It sounds like the door is not closing fully. I started by cleaning the rust and dirt from the 3 areas of slides (top, bottom, left towards rear). Use a lithium grease spray lube and keep in mind to coat the bearing wheels in the channels. On the bottom channel, make sure some debris isn't preventing full slide to the right. Junk gets in there- use a flashlight. The cone shape is the closure assy for safety and should be lubed and the hole it goes into should be clear. The rear switch can be pulled out with a needle nose when the door is open only a few inches. The switch can be adjusted by disconnecting the wires (put a spring clamp on the wires so you don't let em fall into the hole). Slide the collar back on the switch so it sticks out real far- it will adjust when you close it the first time...be gentle closing this first time. The interior light switch doesn't adsust and is probably intermitant- switch cleaner spray will probably fix it from the backside at the contacts but it could also be that the wire is loose connected to it.
good luck....bob
