strange electrical faults!

[hobbit]

Hi, I have a '96 Sharan 2.0l petrol, I have a collection of faults that need rectifying if anyone can assist?!

1) The electric windows will only initially go down when you turn the engine on, you have to wait approx 1 minute before you can make them go up...

2) When you lock the doors (remote or keyhole) they immediatly unlock again, you have to lock them several times before the doors stay locked...

3) When you put the car into reverse gear the very back windows automatically shut if they are open...

4) The reversing lights do not come on at all, only noticed this fault yesterday, tried new light bulbs, makes no difference...

Any help is massively appreciated!!!
