Hi everyone,
I recently tried to get my 1978 280z inspected, but the wipers were so painfully slow they wouldn't pass it. I did some reading and ended up removing the motor to diagnose the problem.
My understanding is that it was likely one of two things:
Motor turning too slowly
Linkage stuck or too tight
After removing the motor and checking everything out, it seems to me that the motor is moving plenty fast, and the linkage moves very easily by hand as well. I've uploaded a small video showing the motor speeds here:
Does everything seem normal? If so, any other ideas on why it's wiping so slow once everything is put back together?
Thanks!
