I pulled them apart and checked the resistance of the micro switches with an ohm meter - no issues.

The motors i hooked up to a 6v power supply and found the main lock motor I could stop with my fingers very easily and if i let it rotate slowly between my fingers it would get to a spot where it would stop and not continue untill i gave it a little nudge.

I pulled the motor apart - there is two indentations in the metal housing you need to lever out - a real PITA to do. but once you get them out the guts just slid out - I used a bit of 1200 wet and dry and and cleaned up the brass contacts - they were very dirty (black) reasembleing was a bit tricky to get the brushes back on to the contacts but not impossible. hooking back up to the powersupply. After the clean up I couldnt stop the motor with out significant discomfort to my fingers - it was a significant change to before the clean up.
