Above is a/the blueprint for a 99 Mercury Cougar, looks pretty familiar to me.
The recent bad weather and excessive precipitation has taken it's toll on the wipers. The bearing in the motor right in the centre of the dash is screaming like Janis Joplin singing Annie Laurie. Spraying WD40 like a Tomcat hasn't silenced the roar of the worn bearing either. Two options are emerging, one don't go out in the rain or two, get it fixed.
The unspeakable third option is fixing it myself which may require the use of a screwdriver, disconnecting the battery and buying a FoMoCo WW motor on-line somewhere. I'm in faith for good weather to prevail for 40 days and 40 nights.
