Door jamb switch: how does it work

[kikkegek]

finally found some time and tried some of the advise you guys gave me.

I don know what did the trick. But I ended up switching the rear door switch and the front door switch...I also added some WD-40 while I was busy. I thought I would end up with a rear door not working and a front door working....but both doors and switches are now working.

so thanks guys...you really helped...

now the lights always go on...and the alarm is triggered when entering through any door...before the driver side door wouldnt trip it ofcourse...because the switch was not working....
