Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Driving home today there were a few times where the horn would double beep,and the dome light would come on. I assume it has something to do with the central locking. Is there a guide to trouble shooting this? Not sure if it is related but I've been having intermittent problems with the passenger door sensor (the central locking) where the windows dont always roll down when the door is open. I rarely have passengers so I haven't gotten around to fixing that yet.

POST 2 / ORIGINAL POSTEROriginal post

And normally when I unlock the doors the instrument panel will light up, (displaying the odometer) but today it didn't turn on until i put in the key.

POST 3Original post

HAve you gotten water in the car? The alarm control is under the drivers seat and if it gets wet, well you will be in trouble. Check that and the plugs that go to the alarm box. Unless you have tiny and paperclip sized arms, you have to lift the seat :-(

POST 4Original post

It is a grounding problem. Search for the issue jcs identified. Drill a drain hole at the lowest point. Clear roof drains Fit a ziploc bggie around the alarm after it has been dried out and is confirmed 'good'.

POST 5 / ORIGINAL POSTEROriginal post

No water around the car recently. Last wash was 3+ weeks ago, and weather has been completely dry since then.

This is a source reference. Confirm exact model applicability in the original material.
