Alarm, central locking and windows won't work

[rdougan]

Hi all,

I have tried replacing the C3 and D1 fuses to no avail.

The power windows drop 1" when opening and closing the doors, but that is it. They never drop when opening/closing the top or using the buttons.

The power window switches are a little sticky. I'm not sure if they work; is there a way to test? I have removed them and cleaned them with electrical spray including all the connectors, but it did not help. I tried using the heated seat switches (as I know they work) but it didn't work with them either.

When I try and lock the car from the key fob, on 2nd press, the horn sounds twice. I think this means that it thinks something is open? but nothing is open. The alarm sensors have no cover; I'm not sure if this is anything to do with it? (BTW, does anyone have a part number for them?)

All other fuses look fine. The fuse in the alarm box is also fine. No dampness/wetness under either seat.

I have no had the car long so I don't know if anything has been done recently to cause this. It still has the OEM radio.

Has anyone any suggestions?

I had a similar problem with my car (996) they other day - the alarm wouldn't arm and would give the two beeps. Indeed, there is a switch that is probably broken, and causing this. Question - when you go to drop the top, will the car actually allow you to lower the top?

The top drops fine. A week or so ago I did have a few issues with it not dropping, but I think I just wasn't putting the parking brake on (haven't had the car long).

Would one switch cause all these issues?

The windows drop (a small amount) when I open the door, however when I close the door they do not (so I have to open the handle a small amount to make the window drop and fit under the top.

Something doesn't add up. If the windows drop down when you open the door, but they are up when you close the door, then they must go back up sometime when the door is open? When do they go back up?

Sorry. They drop and then immediately go back up. Maybe this isn't correct behavior? Maybe they should close when you close the door?

Nope, this is a sign that your door lock switches are non-functional. When you pull the handle, the door senses that you are going to open the door and lowers the window. But, it doesn't see you actually open the door, so it puts the window back up. This is controlled by the switch in the door lock mechanism. Replacing it should fix this problem - see the tech article I have on replacing this...

Ah, that makes more sense then. Strange how it is both doors, though.

Do you think this would cause the window switch/alarm issues?

Definitely alarm issues. Not sure about the windows. If the car thinks the doors are open, then it won't arm the alarm system.

I would try replacing one door lock mechanism and see if that fixes the problem with the windows popping back up. I think it will. If yes, then replace the opposite side in a similar manner.

Ok, excellent, thank you.

I will order a dock lock mechanism and go from there. Finally progress!

Wayne,

Do you know the name for this part of the car, and do you stock it/know where I can get it?



Thanks,
