Wiper motor conversion

[Dodger]

Hey all,

Worked on the truck all day and all electrics are now spot on. A mate of mine volunteered to fit the new electric wiper motor and after much frustration and swearing, it all looks good, except, it's not moving the wipers.

From what we can see the motor is doing everything it should, moving the arms but not much is happening at the wiper shaft. The shaft doesn't spin.

Are these shafts, that stick out the cowl, prone to seizing up or have we done something wrong. Maybe a trick with these motors that we don't know about??

Any advice would be great.

Check the rivet that holds the splined cap (part that holds the wiper arm) to the wiper regulator shaft. Usually they start to loosen up so the arms to not go full arc or will not park right, then fail. This assumes the motor is turning and moving the regulator rod back and forth. Easy to diagnose, not so easy to fix, they are pot metal and do not braze well. I have never successfully fixed one, just replaced them.

Got them working!

The shafts that stick through the cowl were seized. Suppose there is not much use for wipers in New Mexico!

Into the vice and with some lubricant and multigrain s, they loosened up nicely.

Another job down before rego.
