Navigating the deluge this morning and the driver's side wiper suddenly throws a wobbly, stops working in tandem with it's best mate and promptly has a little rest. Permanently.
I'm assuming it's not the motor which no doubt means it's some annoying £600.00 clip or some such? And naturally will require 15 hours labour plus the engine out to be rectified. Yep thought so.
Hopefully it is just that but it may be the connecting mechanism has failed. The drive arm extends from one wiper to the other with various pins, possibly one has sheared and hence loss of movement.
Had your windscreen replaced recently? Autoglass et al do not correctly tighten wipers after replacing glass in fear of damaging prestige cars, apparently.
