Hi everyone I am new to all of this, I have a 91 Laguna 1.6 expression and am having trouble with my rear wiper when I insert the card into the card reader the rear wiper sweeps a couple of times then stops, on other occasions when I press the brake pedal the rear fog lamp illuminates on the dashbord and the rear wiper crawls slowly across the rear screen and on other occasions everything works with no problems can anyone help me with this intermittent fault please

Welcome to the forum. Sounds as if you may have a short in the system. I would pop the rear light clusters out and inspect the contacts as a starting point. Look for water, signs of corrosion (green or powdery build up on contact strips) etc. If present then clean with emery cloth / water repellent / electrical contact spray and try again.

Good advice chris.
That would be my first port of call as well. Definately sounds like a poor/intermittant connection. Check the earth is properly grounded as well.

Hopefully a Renault Tech will see this and help,but it sounds like a problem with the UCH unit.

I'm no Laguna 2 expert though,so I would wait for their comments first!:)
