Gord - I have tried in vain to determine the maker of the wiper motor. Short of pulling the unit out (which I am trying to avoid until I know what my ‘fix’ plan is) the best I can find are two serial #s. One is likely a “quality control” #.
QC 200801
And the other is...
EX 013L 12V
No other markings or ID on the unit. Anyone able to discern the manufacture from this?
