My microswitch has not worked for 2 years. I had a latch on order for 4 months with British racing group but they could not give me any idea of when the latches would become available. In my opinion a business should not charge you full price for something that will not be sent within a reasonable time. It took over 2 months and several calls and emails to finally get my money refunded. Has anyone ever received one of these?? My experience with them was horrible and I will not use them again (if I can avoid it).
I unplugged my latch, so the car always thinks the door is shut. Things to know if you do this. If your DRL are deactivated (like mine) then you will not get a warning that you have left your lights on (Done that a billion times). You will have to lock your car manually by holding up the handle when you shut the door. The window will not position itself so the window will make contact with the top gasket when you shut the door. Dome light. Still these characteristics are better that the car thinking the door is always open.
Since we can't get these parts I decided to rip into the latch to replace the microswitch. I know some people have said they have done it, but nobody seems to be willing to share how it was done. The latch is pressed together with "rivet like" posts and without knowing the internal anatomy, it looked to risky to make a surgical cut in the plastic and possibly screw up the whole thing, which could make the car undrivable. Not a big deal if I could get the part! While I had the latch on the bench I lightly pried it open and sprayed contact cleaner in the area that appeared to house the microswitch. Dirt came out and I could hear the cleaner sizzling in there. When I reinstalled the latch it worked like new. Maybe a fluke or temporary fix but it works. The microswitch is on top of the latch and towards the outside.
If somebody has this issue here is what I would try first before taking your door apart.
1. With the door open. Use a screwdriver to engage the latch to the closed position.
2. Loosen (do not remove!!) the 3 hex screws that hold the latch to the door.
3. Use a small screwdriver to make a slight gap between the metal plate and the plastic case of the latch mechanism. Slip the tube of the contact cleaner in the gap and spray towards the back (under the upper mount screw and above the latch hook).
4. Tighten screws and release the latch.
I know others have mentioned spraying electrical cleaner in there but maybe this helps with exactly where to spray.
