Sticking Wiper
12 Answers
Hi my wipers stick sometimes when I turn them on once I rub the glass and move them manually they work fine and continue to work, are they just sticking to the glass? If so what can I put on the windscreen to prevent this?

For more on marking an answer as the "Best Answer", please visit our FAQ.Here in the U.S., and I suspect in the U.K.,a properly working wiper needs to make a slight turn at the end of each stroke… it's flexible about half way up the width (measured from wind upward to the holder mechanism) but as it grow older is becomes stiffer and doesn't do the little flip. This is when, in my experience, the blade begins to stick on the window. Solution? New blade time.
If this is the course you take and you intend to do it your self, be aware that many newer cars use a different length wiper for each side of the window so be sure you buy the right ones...

Are you sure it's the wiper blade sticking to the windscreen and not the motor failing to start? Do you see the blade trying to move and sticking or does nothing happen?
There are two electrical feeds to the wiper motor, one from the switch and the other directly from the battery - the latter goes to a switch INSIDE the motor. When you switch on the wipers the first feed starts the motor. This operates the internal switch so the motor is also fed directly from the battery. If you switch off the wipers the motor continues to run, fed by the second feed, until the blades reach the "parked position", when the internal switch turns off the motor. If there is a problem with the feed via the wiper switch the motor may not start because it is not being supplied with power. Moving the blade manually may be enough to operate the internal switch and start the motor.
Perhaps the wiper switch is faulty or maybe it's the relay between the swich and the motor which is giving problems.
If you can operate the wipers with the blades off the windscreen (I can't on my car because they catch the bonnet) you might be able to find out whether it's the blades sticking to the windscreen or the motor failing to start.
