Intermittent wiper adjustment - can it be done?

My intemittent wipers are moving too quickly and I wonder if they are adjustable?

Some are, some are not.

I would help immensely if we knew what you were driving.

If they are adjustable the mechanism with which to adjust them should be on the same stalk that turns the wipers on and off. The owner’s manual should have detailed information about this.

I’m driving a 2001 PT Cruiser. I’ll re-check the owner’s manual to look for the answer.
