My big problem is my wipers, I took the car to my garage and explained the possible cause was the fuse or earth and the tips I was given. Nothing worked which leaves me in a mess.
You might find it helpful to start a new thread that deals specifically with this issue.
I'd start off by determining whether the problem is with the wiper arm, the motor itself, or the electrical system.
The wiper arm is the least likely culprit, but can be easily checked by turning on the ignition and then starting the wiper. Check the wiper arm at the base. Is the wiper motor running, and is the arm failing to lock to the splines that make it rotate?
Beyond that, how handy are you with a multimeter?
