Alarm Question

Hi,

My TD5 110 was recently in the garage for a week with the battery out. The alarm worked fine when it when in (but the interior lights did not work). When I go it back, I changed all the door switches and the interior bulbs. Now, I cannot activate the alarm. I get 2 beeps (door open). If I take the passenger door switch out of the A pillar, I get 3 beeps if I hold the plunger by hand. If I leave it in the door pillar, I get 2 beeps. Anyone know what the 3 beeps on arming means? Probably connected but if I turn the interior light to switched (comes on with door), it take 10 minutes or so to go back off. I believe the driver door switch is OK as the red LED on the dashboard comes on when I open the door if the alarm is not activated but the immobiliser is (automatic mode). I am checking for earth shorts but none found so far. Cheers.

Update:- Have narrowed it down to the passenger door switch. If I remove the passenger door switch, it all works, if I connect it again, it stops working. It can't be a short as that is what the switch is designed to do. It is a new switch, and I do not think the wires are causing the problem. Any thoughts?

Does it have the same problem with the passenger door open and closed when alarming?

have you checked that the new switch when fitted and door closed that the connector is not fouling door pillar and the switch has the right amount of travel to actually breaks the circuit
