Sometimes my car wont detect when my doors are opened; Its completely random, the dome lights will come on but the step lights do not. The open door symbol in the dash doesn't light up either. What electrical part is the culprit here?
Had a similar problem, had to bend one of the contacts just a little bit. Be careful if you do, it seemed a little brittle. Touched some fine sandpaper to the contacts to clean them up and haven't had a problem since.
94SL, test pipe, 3SX crank pulley. 180K and still ticking.
Open the drivers door. near the rear of the car on the BODY section you cant see with the door closed. where the striker is that the door closes on. there is a rubber boot looking thing. near where you would see the tire stickers and body vin number stickers.
It is screwed in on mmine. phillips head. rubber boot. about 1 inch by 1 inch.
Unscrew it and pull it out some.
Fish the wire out some and unclip the plastic/rubber door thing from the connector.
DO NOT LET THE CONNECTOR AND WIRE FALL BACK INTO THE HOLE/DOOR JAM. just wrap some tape or bend it sharply or zip tie so it wont fall back in.
the rubber boot/ cover just slides over so just unslide it off the metal switch.
the switch has 2 little clips holding it together. this is on the plastic sides near where the connecor connects. pry them apart.
The whole thing comes apart at this point and there are springs so go easy and do this where parts can fly or fall and NOT GET LOST.
on all the metal contact surfaces spray some carb cleaner on them. then take a pencil with an eraser and rub on the metal contact points. or FINE sand papaer..
spray a small mist of WB40 in the connectors and plop the spring back in and reclip the switch back together. take it back over to the car and slide the original rubber boot back over it.
Reconnect the clip/harness. and bolt it back down to try the rebuilt switch out.
Now do the other side.
Seems as if moisture gets in the switch and corrods the copper connections like the inside of an off VCR remote. Cleaning the contacts fixes the open circut and allows your lights to work just like new.
Have a good day.
* edit: and all this great tech from a guy with bad karma.. boo.
