Nothing like a bit of father/son bonding over a soldering iron (in my case not a very good iron).
Number one son drove up to see us this weekend and on the journey discovered that the remote lock for his car tailgate didn't work any more. A quick search of the interwebs suggested that the cause might be a broken wire. Indeed. And it turns out that the rear wiper on our car had broken for what was probably the same reason.
So, what with it being a nice day and all, we went outside and peeled back a couple of rubber boots. As it were. Turns out we were both right. In my case doubly so as two wires had snapped. So we passed the soldering iron back and forth rather like a pipe of peace as we made good the damage.
I find it really surprising that the wire can fail like this, and that car manufacturers are happy for it to happen. After all, we haven't actually spent days on end opening and closing the tailgates of our cars, these have broken after fairly light use. Oh well, as long as they last through the warranty, I guess that is what counts here....
