1. resetting the windows (all the way down & hold button down for 5 seconds, all the way up & hold down button for 5 seconds)
2. check battery connection - particularly quick release -ve. Make sure terminals are clean and when connecting push them as far down as possible before tightening, then check it's a tight connection.
3. check battery condition: if it's not good it can cause all sorts of electrical problems and consider replacing. If you do decide to do this make sure it is the correct size: height as well as footprint. Strap over the top should be a snug fit. If it isn't it's the wrong size battery.
4. get it checked out by someone who knows what they are doing. Can save a lot of time & money in the end.
