now do you fix the inside air vents.

Theyre an elctrically actuated blend door motor. Check for powers and grounds if good you cant fix. Must replace as an assembly Good luck

I would try changing the settings first. Turn the open on start off and then back on. If that doesn't work then I'd check cor fuses, then I'd go to a shop.

There is a little circular yellow clip that can crack and stops the vent from operating. Just had mine replace at local independant garage. £ 5-20 for the replacement clip and half an hour labour. That's it !

where to find it

whare is it located
