Any ideas why my passenger window moves up and down an inch or two every time I press the switch?
After pressing the switch, the window moves a little but then the motor stops and the puddle light and light in the switch go off for about 1s then they come back on. It's the same if I use the driver side switch. Pulling or pushing the glass by hand to 'help' the motor makes little/no difference.
Trouble codes show B117e-13 and B117e-19 but i can't find what these mean.

 

Cool. A 1977 with power winders. Noice.

 

Replaced just the motor and now it's working perfectly.

 

Now that is working, see if you can figger out what failed for the motor?
Can have a spare in your inventory.
