Tiny Electrical Problem

:uhoh: 1999 Chevy S10 ExCab Xtreme. I'm not really sure what my problem really is....at first I thought I had a bad light switch on the door, you know those pin switches, because thats what I was told by the tech that installed a Viper alarm on the truck last weekend, becasue you would close the door (passenger side) and arm the alarm and it would chirp once and then a couple seconds after it would chirp again like if you left the door open, so I bought a couple switches on ebay, I swapped the "bad" one with one of the ones I just recieved, but that didnt fixed my problem, so I finally decided to test the switches with my tester (i know I should've done this before buying the replacement ones :icon16: ) and they all work just fine. I was checking the conections on the driver's side, since that side works just fine, and when I check for continuity on the black and the orange on driver's side, I dont get anything, then I re-installed the switch (driver's side) and I dont get continuity untill I realese the pin on the switch, but on the passanger side, which is the one Im having trouble with, I get continuity on the black and orange wires with the switch not even plugged in.
I dont know what my problem could be, Im assuming the insulation of those 2 wires is worn out and the wires are making contact somewhere, but I really hope is something else, before I start taking all my dashboard apart:frown: , I didnt have a lot of time today to mess with it, thats as far as I got today, I just bought the truck last week, thank you very much everyone for your help:smooch:

The switches are accessible by going under the lower knee panels so no pulling the dash - cheapo plastic and most agtermarkets are not the correct size so dealer item. Sure its the switch and not the alarm as if wired into the door switch that auto interior delay is in the headlight switch and thats what causes that second chirp. Quiz the installer and ask another or call Viper tech on this - maybe an option to fix by diff connection.
