Drivers side power window went down and wouldn't roll back up
ok its just an electric dc motor.
what can cause no up, failure.
1: not getting full 12vdc to motor,.(uses a $10 voltmeter to not guess) if why low, then the power feed is bad there. say below 10v. keep in mind motor overloads can cause V drop,.(V= I square x R, ohms law)
2: guides bad overloading the motor.s
3: if the hot wiring the motor does not move it up that means.
what,? motor bad, or guide jammed. (reverse wires to go up, reverse to go down, 12vd on one wire, ground the other. 2 pins.
so we remove motor and operate it by hand to see if guides are ok,. (not hands on motor but its guide drive end)
4: later years, they added a child proof clutch to prevent johnny from crushing suzy head for fun. really. and clutches do fail and slip, you'd hear it slip, I cant.
or if the guide is jammed said clutch slips and thinks bad johnny deal.
i think yours has no clutch. in 2000. my 04 did not.
it's just motor , a switch and a guide.
many this old are bad guides. jammed. up.
