W202 C200 bizzare electric window glitch after battery swap
I've just changed the incredibly durable 10 year old MB branded Varta battery on my car earlier today, swapped it for a Yuasa one of similar design and capacity. I did everything right....disconnected the negative terminal first, didn't have the key in the ignition or anything turned on. I was a bit surprised and a little shocked (okay, not literally) when I got a spark as I reconnected the earth, but everything seemed okay afterwards with the exception of having to reset my clock and install all of the radio stations back into my radio.
However, after a little trip to the shops I tried to put my drivers window up the bit I'd dropped it by pushing the console switch all the way, and it wouldn't go. The window moves fine by pressing to the half-detent, either up or down, until you release the button, and goes down if you press the button all the way - but it won't 'lock-on'. But to raise the window, if you press fully to the locking stage, it won't go. It only goes up if you half press and hold.
But here's the weird bit. I tried all the other windows. Front passenger door - the same. Rear nearside door - the same. Rear offside door - OKAY! Then....The rear nearside door started working normally too. Finally, my front passenger door came back to normal, but the drivers door window persists with its 'half a push to raise me' syndrome. Whether changing the battery has caused this or whether it is just a happy coincidence (sic) I do not know. Maybe it will have all healed up by itself in the morning but I'm at a loss to understand what it happening here. Ruddy software!
