Yes, if it does not the motor is bad.
Switching the power will make the motor run the other way (up and Down)

Need wiring diagram for 96 honda accord power windows

If this is any help you need to check the voltage with your meter between the two wire, do not put one lead of your meter to the plug and then the other to a ground, that's not how it works. Again you need to put one lead of you meter to on side of the plug and the other lead in the other, now try you switch up and down you should get at least a 12 volt reading on up and down, they usually have a really that switch the 2 wire so depending on weather you are trying to go up or down determines witch wire has the 12 volts and witch wire is the ground at that time, so if you read between the two wire you should get 12 volts if you don't then ether you switch is bad or there is a bad relay. Or you may have a bad ground, it look like you checked and found that there is 12 volts at the plug you have lost the ground side with in that Circuit So That this is so long I am a talker I hope this helps.

What causes a power window on a 2001 durango to go down but not back up

Possible bad window switch. If the window motor were bad, or if power was not getting to the switch, the window wouldn't work at all. The switch should be tested for correct operation. Remove the switch and apply 12 volts to the power terminal of the switch. Then toggle the switch and use a 12 volt test light to confirm continuity on the up and down terminals. If it is defective, replace it with a new switch.

1987 corvett both windows went up by themselves now they won't go down I have 12 volts on both wires to the motor is there a relay some where

12 volts when? going up or down? both windows? check the switch. the black wires coming out of the switch is ground. if those have power, then check the ground connection. G201 is near the left side of steering column. the motor should have power on one wire and the other is ground, they just swap to go up or down. I suspect the switch is bad.

I cannot operate windows on 2002 impala. you can run a seperate 12 volt source to the motor and it will operate window. also all the windows don't work. there is 12 volts at the switches but they will...

Sounds like you are missing a good ground.

Here's something to try. There should be a single black wire on the connector for the master window switch. this is the ground for all the windows. check for power by back probing that wire with the connector plugged into the switch and a window switch in either the up or down position. If you see 12 volts than the ground is bad. Use a jumper wire from that wire to a known good ground. If the windows start working than you will need to trace that wire to find the break. The most common would be in the harness in between the door and the body of the car.

If you don't see 12 volts with a switch in the up or down than remove both connectors from the switch. test continuity between the pin that the black wire goes to an any pin that the 8 wire connector plugs into. There should be continuity. If there isn't that the master switch is bad.

If you have any question let me know.

My window on a 2006 dodge ram 2500 mega cab will not go up but role down

these should be the correct wire colors
light blue wire and a white wire drivers side
brown/white wire and puple white passanger side
meter these wires at the drivers side switch these wires should meter +12 volts in on direction either up or down and -12 volts in the other direction either up or down
Example: put the red probe on the light blue wire and the black probe on the white wire throw the switch in the up direction you shpuld get a reading of +12 volts and if you throw the switch in the down position you should get -12 volts. if the switch is in the nuteral position it wont give out voltage.
if voltage is not present in when you flip the switch then the switch is bad and you will need to replace it.
if voltage is present your motor or motors transmission is bad. sometimes the motor is connected to the transmission and when swaping out the motor you have to swap out the transmission too. most of the times you can seperate these two.
the reason you window will go down and not up might be beacuse the wieght of the window pulls the window down but the transmission is broken and the motor alone cannot lift the window up.
hope this helps.

My 1997 Pontiac Grand Am driver side window will not roll up but passenger side works completely

I have a 1999 grand prix and I had this same problem. It was my switch on the drivers side cluster. I bought a whole used cluster on ebay for $25. We tested my motor by applying power to the motor with 12 volts from a battery. a power window motor window has 2 wires. put (+) on one, and (-) on another and one way will take the window up, the other will roll it down.

1966 chevelle with 283 cu. in.

the r terminal only has 12 volts on it when you are cranking the starter over. so the wire that goes to the r terminal goes to the plus side of the coil then the wire that come from the switch also goes to the coil this wire should have only about 8.5 volts on it when switch is in run position the r terminal puts 12 volt on the coil while cranking the motor over the when the switch is in the run position there is 8.5volt on the points so you don't burn the points out the diode kit i don't no why you need it unless the don't what any back feed volt to the r terminal in the run position so i would put it in line(series) with the r terminal wire the flow on the diode is from the -<- this side of the diode goes to the coil

91 dodge dynasty blower motor

trace the two wires by analyzing which power are you missing...

run a wire from the positive of the battery and put the red wire of the volt meter to it and place the black wire of the meter to the black that goes to the motor.

if there is 12 volts, you have a negative terminal to the motor.

if you dont have, then you dont have the negative terminal to the motor.

next transfer the wire from the positive terminal of the battery to the negative terminal of the battery.

now put the bllack wire of the meter to the wire and test the red /or blue wire that goes to the motor.

it should have a reading of 12 volts.

if there is no reading , then there is no positive 12 volt present on the blue/red wire.

from these test, you can know which wire does not have the power.

that is what you are missing..

tnx 4 using fixya,




you could have just missed the black wire to be screwed on the housing of the blower motor.
