Jeff,
 
I had a similar problem with the wipers on another vehicle which was cause
by a lack of lubricant on the shafts to which the wipers attach. If the
wipers haven't been used for quite some time, they may simply need oiling.

Hi All,
I finally got my replacement wiper motor in this weekend, but am not sure
that it is quite right.
It moves fairly slow and almost grinds to a halt on a dry windshield, and
the "high" speed is even worse and can barely move.
It acts OK with the wiper arms off or on a wet windshield, but I still
wonder if it is right.
I used a replacement motor that was sent to me. It looked the same, but the
origin of the motor is unknown. The only real difference I did notice is
that the main gear in the original has 120 degrees stamped on it and the
replacement had 105 degrees. At first I though this was a position marker
for the gears, however the more I think about it, I am lead to believe that
the number indicates the arc that the wipers will follow.
Now, if this is the case, would the 120degree gears have more torque and
cover more of the windshield than the 105?
Or, could it actually be a weaker motor even though that part looked exactly
the same?
I am leaning towards changing the gears because I wouldn't think that they
(Lucas) would radically change a 14W motor for each application.
 
Can anyone add their opinion/ knowledge/ experience?
 
I'd really like some second opinions before I go ripping the whole lot back
out to change the gears.
 
Thanks,
Jeff Caraway

Hi Paul,
Thanks for the suggestion, but I have oiled and lubed everything I can
think of.
Not only did I grease the motor gears before I put it in, but I greased
and WD40-ed the heck out of the wiper linkage to no avail.

Hi Jeff,
Ah, the fun of owning an exotic car! Under the category of "when you 
hear hoof beats, don't think Zebras!" To operate properly the 
wiper motor and wiper switch must have a good ground.Check that you 
have a really GOOD ground for the wiper motor.(don't assume that if 
the ground wire is in place that it is good... clean all the contact 
points and if necessary,put a temporary jumper to the negative wire
at the battery until you are positive you have a good ground)  One of
the wires from the wiper SWITCH should go to ground and it should be
black in color. (all the ground wires should be Black) (On my car it 
is located between a yellow with a light green stripe and a red with a 
light green stripe on the wiper switch) Be sure that this has a proper 
ground as well. 
Usually the ground wires go to a "commoning connector" and then one of 
the wires eventually goes to ground.  A lack of use, sitting in a 
humid climate etc. will make all of the connections "flakey". And a  
lack of a proper ground will result in the symptoms you describe 
for your wiper motor ie. sluggish, lack of torque etc.  Won't do 
any thing for the degree of swipe, of course.
Have fun,
Mike Denman
