Wiper Motor on 2005 Volvo S40

After the first snow fall just yesterday, my wiper arm came loose or seemed to slip a gear on the driver side. When turning the wipers on the passenger side move in full motion where as the driver side fights to move only a few inches.

Can someone provide some insight/instruction on how to tighten or replace the wiper motor?

Volvo's often have a plastic cap at the end of the are, pull up on that cap to expose the wiper arm nut. Tighten that nut and you should be OK. Tighten the nut on the other arm as well. These come loose and should be checked at least once a year, preferably before winter.
