What car?
what year?
2 speed? 3 speed?
Did it ever work correctly?
Hot when running or not running?
What does the noise sound like?

It's an electical device, that's what they do. Most of the electricity used by an electrical device is transformed into heat. I forget the percentage but 70% comes to mind.
67 barracuda 2 speed it only has one speed for now
It could be mechanical resistance (bearings, gears, grease) or electrical ( brushes or somehting deeper).
First identify which wiper motor.
As best we've put together so far, there were two, two speed wiper arrangements in 1967.
The motor of one has a white plastic plate over the gears.

The other is a variable speed motor with a two speed switch.

My only advice is to READ THE SERVICE MANUAL. I'm not tryn' to be mean here. You can download them free at MyMopar. There are differences between variable, two speed, and three speed systems. download 2, 3 differnet years manuals, because some have different/ better troubleshooting info. Section 8, electrical
Don't discount simple stuff like BAD BUSHINGS in the wiper hubs

Take pitman arm off motor and run it. If the problem persists the problem is in the motor/gearbox. If the problem goes away the resistance problem is in the pivot posts. It can't just toss the plastic ball socket bushings from linkage like later models do. It doesn't have those.
Our first 67 had the cycling circuit breaker inside the switch. It eventually failed (bi metal strip cracked in half). I figured out how to mount a substitute on outside of the switch. The red 67 we have today was going to do the same if I din't fix it. Fault was in the drivers side pivot post mostly on both cars. There was a little wear in the right pivot post but not so much binding. Drop it, rotate housing 180 degrees gets the pressure on a less worn side of the bushings.
To take one of these pivots apart, new bushing and good shaft taken from a right pivot to replace a severely worn shaft in left pivot was a challenge. Friend with a milling machine helped.
