Honda CRV 2011 passenger window stuck closed. Told it was a £500.00 fix. (YEAAHH)
Left it but stayed closed when tried. During wintertime I was not using the car so disconnected battery due to the power comsumed by the usual gadgets.. Four weeks later reconnected battery and guess what. The window works fine. Seens to have been just the on board electrics conputer getting confused. So try it and see. Can't harm.
