Vauxhall wiper linkages are prone to dis-simillar metal corrosion & seizing up, (having aluminium casting with steel pivots) I recomend keeping it well lubricated. Try using a penatrating or easing oil and see if it helps. If this works, I'd recomend removing coverings (bit of a fiddly job) and greasing all moving parts. If it does seize, it can strain the motor. Both the linkage and motor are expensive dealer parts, about £120.00 for the linkage alone! Hopefully this will help
