Passenger Window Problem

[Transporter]

Please read the whole post then make your suggestions.

Front Passenger Window will go down but not up.

I have a new known good drivers side window control because the driver's window would not go down and it was the module so I replaced it and I used the old one that worked the passenger window before to prove the new driver's module is still good as this new problem started months after replacing the driver's module. I moved the passenger switch to the rear window and the switch operates the window properly up and down. So both Driver's switch and passenger switches are known good.

So the motor should be good since it will go down, both switches are proved good, what else can it be?

Using a dmm, check for voltage at the connector for the window motor while operating the switch. If there isn't voltage there move to the next component in the circuit and check for voltage again. Keep doing this procedure until you have voltage. Once that is found, you have zeroed in on the component or segment that is giving you the problem. It will be in the last segment / component between having voltage and not having voltage.

If you have voltage in both directions at the window motor connector then the motor is suspect.

That is an idea, but if the switch LED has power, there is power to run the window down, where don't I have power?

No more suggestions? Its not the switch, not the motor, and since it goes down, one would think it wasn't power. But I am down to thinking that the only reason its not going up is lack of power but not because of the switch or a fuse. Is there a common place that a wire could break or be cut? Can't see it being a connection as the connectors have multiple wires and again it wouldn't go down if a connection was lose.

Lastly, does anybody know which wires would apply power to force the window up? I show three wires on the Skimoes, Tan/LtBlue, White/Yellow, and Yellow/Lt Green.

what prints are you using???

At the passenger side motor you should have TWO wires going to the motor a red/yellow wire and a yellow/red wire


Take and make up a set of test leads and hook them up to your battery

Part 1
Then take the + lead and connect it to the red/yellow lead at the motor and then take the neg lead and just touch it to the yellow lead. the motor should run

Part 2
Then take the + lead and hook it to the yellow/red lead and the neg wire hook it to the red/yellow lead the mortor should run in the opposite direction then it did in the first part

Thanks. I have the same Skimoes as I was referring to the wires on the other side of the switch. I have Red/Yel and Yel/Red for the passenger side window motor. Next is how bad is it to get the door panel off?

OK to the prints But by going directly to the motor you will prove that it works in both directions If the motor proves ok then I would hook up a volt meter to the other line side connector for the motor and check for voltage there . Operate the switch and you should see a plus or neg 12 volts depending on which position (up) you put the switch in then put the switch in the other position (down)

Its not the motor. Now I am really stumped. I applied power directly to the motor and I can make the window go up and down (thank the stars that the window is now up because it was a bit cold inside driving at 65MPH in 39 degree weather). I applied power to the wiring to the motor from the switch and the window goes up and down. I took the switch and put it in the rear window and it operates that window both ways. Took the rear switch that is known good and moved it up front, No Joy! I have voltage where I should.

Am I looking for an open Ground? The window goes down fine just not up. Looks like they all use the same Ground so how can I have an open ground if the window goes down just fine? Lastly, could this be mechanical meaning is there anything specifically different in raising the window versus lowering it?

So to recap, Switch is known good. LED in window switch is illuminated. Motor is known good. It can't be a voltage weak Lock switch because the window will not go up from the drivers switch panel either (and other windows work when Lock is off). I have power at the connector on Yellow/Lt Green and on lines 3 & 5 when I press the drivers side window switch for Up or Down and can operate the window from the connector with correct ground and power. The wires for the switch don't look pushed out and are not bent or damaged that I can see. It seems that the only thing I can't prove good is the actual connection between the switch and the wiring harness connector but both Ground and Power are available there. Since neither switch will raise the window it leads me to believe it is something common to both switches which are the motor, main power line, main Ground but the problem with that thought is the window motor works fine with outside voltage and all other windows work fine so its not main power or main Ground, plus the window always goes down just fine! So again I am back to something in common with both the DOWN front passenger routes as everything else works.

The only things in common to both switches making the window go down that I can see are the actual motor, passenger window switch, and the wiring harness connector the passenger window switch plugs into. Did I miss anything? Is there a way to test the harness connector?

if the motor ran in both directions when you applied power to the motor leads then your problem is in the wiring or switches.

As stated earlier take your volt mater and test at the line side of the motor connector put your leads on the yellow/red -- red/yellow wires operate the switch up and down and you should see +12 V in one direction and -12V in the other direction
