Wipers Not Parking

[Richiejh]

My 2005 C8 has just stopped auto parking the wipers. They stop a few inches up the screen, any ideas what might cause this?

Could be a problem with the wiper motor or any linkage.

use a diagnostic and see if you can park the wipers with it. if that dosnt work then take pauls advice and check linkages etc

Thanks for your replies, another job on the list! I'll post again when I find it.

You can operate the wipers at high speed, if they overshoot off the front windscreen, then:

1- The wipers are fitted one or two notches incorrectly.

2- The joint at the base of the wiper arm is worn out. 

 

If you switch off, then pull the wiper stalk, the wipers should rest in the middle of the windscreen. Left the wiper off the windscreen and wiggle it to check the play.

It hits the side of the windscreen on full speed. This problem has only occurred in the last week and both wipers are too high. They work perfectly but park too high.

Today I managed to get out and fix this problem! After using diagbox to confirm the park signal wasn't working in decided to take the wiper motor out to have a look at the park switch. It turned out to be one of the contacts on the park switch had worn down so wasn't touching any more, a quick bend and all is back and working again for now.

Good to see it only cost a bit of time to fix. Years ago British Leyland cars used to have a plastic wiper motor parking switch and the plastic plunger used to wear down so it did not work. Fortunately the switch could be replaced at low cost.
