Switch, relay or Wiper motor?

Hello everyone,
'71 442, 2 speed wiper motor.
My wiper motor will not activate unless I manually help it move. Once it starts, it is ok.
Please help. :P
Thanks!

1) Shows that there is at least some current getting to the motor
2) Bad commutator or brushes
3) Bad ground
4) Bad or dirty connections, anywhere
5) Too high a resistance in one or more components

Etc, etc

Once you get them moving, do they move at normal speed? Do they park properly?

Also is the wiper transmission binding anywhere?

No binding that I can tell.
Once moving, they move and park properly..
I'll pull and clean.
Thanks!
