| OK, alarm problem back again - went off at 11pm last night.
When I went out to check, I noticed the passenger window doing the up down thing, going crazy. Reason I hadn't seen this before, is that the passenger window was not working at the time of the first round of alarms. I fixed it last week with the 'bang, bang, bang' method.
Seems highly likley now, that the problem is the switch in the door latch. I'm going to source a new one and replace over the weekend. I'll do a write up with photos for anybody that might need it in future. |
