vent switch hard to push to defrost

[kully 560]

hello again, just looking for some help on my vent switch. the switch does not want to go to the off position but cycles through the bilevel,  floor, and vent. it does go to the defrost position but is hard to push there. but it does go so just looking some help on what parts to order for the fix kind regards

The control cables are just pieces of stiff wire that often get bent if people try to force them when they stick.  Once that happens they are shortened, plus they flex at the bend, and don't work correctly.  They can be straightened and will work again if they are lubricated.  You'll have to take things apart to know what the problem is.
