Technical help please - windscreen wiper problem

[wreckingball]

hi

would anyone be able to advise me on a small problem i have on my brava..

the windscreen wipers when turned on will kinda half work for a bit and then completely cut out. when they do work they are very juddery and only work for a couple of wipes then cut out completely.

any advise as to what the problem could be and how i could fix it would be great as it is very annoying :bang:

thanks for your time

first thing to do is check the signals the wiper motor is receiveing. use a multimeter at the motor wiring connector and test that the motor is getting sent a 12vDC signal of often as it should (check all wiper speeds for a change in signal occurance). if you dont have a multimeter use some wire and a 12vDC bulb (car bulb). when the wiper motor gets a signal the bulb will light up.

if the wiper motor is getting the correct signal then it probably means the wiper motor or relay is faulty (relay is built on to motor). if the signal isnt getting to the motor then you probably have a problem with the wiper stalk switch or the wiring in the circuit.
