    Hi, I hope some of you can give me a hand with this.

    The rear wiper is not moving at all. Demister and washer do work, as well as the front wipers. I've taken a look at the sticky not for astra pre 2001 (mine is 1999) and there is only one fuse for front and rear wipers, so it is not the fuse. The relay for the rear wiper does click when switched on, so I guess it does work. The rear wiper motor has a connector with three cables blue, brown and black/violet. With a multimeter I've measured that brown is ground and black/violet is 12 volts. But when I switch on the wiper in the steering wheel. I don't see any voltage in the blue cable. I believe it should change from 0 to 12 as the relay is actuated.

    Could it be that the relay is faulty? If so how can I pull it out from the fuse box (it is kind of stuck doing a normal force and I don't want to break it)?
    How can I test the wiper motor with the multimeter to know it works or not?

    Cheers.

    I had everything you describe on my Tigra. It turned out I had a broken wire under the roof lining where the hatch bends the cables with the constant opening. I suggest you pull the press studs or whatever away and have a look inside the lining. Mine was pretty obvious because the broken wire (brown in my case) had broken off at the connector and was hanging loose.

    Thanks, it was in fact a broken cable. Actually the isolation plastic of all the cables have hardened so much that all the cables going to the tailgate are about to snap.
    Opel should have used a better material for this cables.

    Glad you got it sorted. With regard to the insulation material on the cables I suppose it's done well considering the age of your car. My Tigra was a 1995 and Vauxhall want people buying new cars.
