How do you get wiper off cowl off

How do you remove wipers and cowl to check fix leaks into cab??? I t9ok the nut off still feels like it stuck on

 

Give the wiper arm a few good taps with your palm right at the pivot, thats usually enough to break them loose.

 

Put a little spritz of WD-40 down the stud too.

 

Those wipers have spline grooves so they can be a paint to pull off. Spray a little lub on the studs so that it seeps down to the grooves. You just have to wiggle it side to side as you're pulling straight up.

 

Pretty sure they also sale a tool specifically for wiper removal.

 

They do.
But a battery post terminal puller works in a pinch
