How do I fix this electrical problem?

I have a 2001 Renault Laguna 1.8 authentique. For some reason lights have started dispaearing i.e apperently I only have one wheel according to the on screen image of my car.

I am not to fussed about that, the real problem is the wiper system. Only the fastest setting works and even when its selected the blades are very slow. When I have low amounts of fuel this setting doesnt work either.

I have taken the actuall system apart and and there is no obviuos friction causers so I assume its a power thing. So I then recharged the battery but still no luck. (is there a chance my battery could be casuing this if its old or even my alternator? Please help I have my MOT soon!

Regards

Update:

Also just thought I'd mentioned when I activate one of the window controls (to make window go up ow down) rear wiper is also activated! Random~!

    Sounds like an earthing problem - may be difficult to find.

    Your wiper problem may be caused by the stalk electrical connection which has worked loose. Had this before on a laguna.

    Disconnecting the battery and letting the ecu reset usually sorts out the random electrical problems which are caused by occasional voltage spikes.

    Try checking the earthing on the electrical system. Problems here can cause all sorts of problems with electrical system.
