Fixed - Passenger Power Window troubles / wiring stuffs

this is a RHD celi, drivers window is fine.

i've had a problem for a while where i can put the passenger window down but not up. sometimes playing with the switches on both sides would eventually get it to go up. tonight no more. i've taken the panel off the door, replaced the passenger switch with a newer one, no difference.

- the window was fully down. when i press the down button on either side, the Voltmeter on the dash drops like normal. and i can hear a slight click from the pass door.
- When i press up on either side, the Voltmeter on the dash does not move and there is no noise.
- The car is sitting outside tonight and tomorrow while i work, so i took out the 4 10mm bolts for the window motor, and manually pushed the window up, jamming a screwdriver in each end to keep it pushed up.
- Going to try replace the motor, after i test the plug - saw a post where you connect a 12v battery and see if it works.
- i'm sure the system could use a clean

1) How can i manually put the window up without unbolting the motor, so it is securely in place?
2) Where is the fuse for the window motors? looked in the drivers side (RHD) kick panel and engine bay. Would a fuse cause it to go down and not up?
3) I've read there may be too much tension for the motor to handle, but pulling up while pressing the button does nothing.

cheers i really need this car secure where i work, security guards eat too many donuts.

 

Re: RHD Passenger Power Window troubles

Cheers man good advice. I have each door spare in a warehouse, going to grab the pass motor tomorrow and give it a try.

the rotating arm that moves from vertical to horizontal - seems like the teeth are pretty worn, like an old bicycle gear.

just to clarify

the last while its been dodgy, one way of getting the window up was to put it down then slam the button to up with another finger. tried that tonight and ended up with the window fully down.

The switch is trying to push the window down, as it normally would, but its at the lowest point.

When pushing up, the switch does not register a response of motor/mechanism sound or voltage drop.

-Could it be the wiring? I think that if it were, it wouldn't go down either.

 

Re: RHD Passenger Power Window troubles

Hey i tried a battery on the motor and the window will go up and down.

Got electrical contact cleaner for the switches, try it in the morning. Going to check the kick panel first for anything obviously fried.

What are the chances of both switches giving up at the same time? Just my luck ey.

Now the window's up as far as it will go, It's about 1 cm forward and 2 cm down from where it should be (compared to drivers window). This explains the wind i've had coming through, just need to adjust it after it's working again.

Got my replacement glass ready and cleaning stuff for the mechanism and now i don't need to take it apart. Typical but at least it's secure!

 

Re: RHD Passenger Power Window troubles

well i've gone and done it now. I rebent the copper on both switches i have and cleaned the black stuff off with my shirt. Today the passenger window went up a couple of times. I was getting ready to put the panel back on the door and tried to adjust the window a bit, its sitting about 1 cm forward.

I went to put the drivers window down to compare the positions, it tried to go down but felt stuck. Opened the door and tried again, then i noticed the voltmeter on the dash drop to about half. I turned the car on, no worries, revved to charge the battery.

Now there is no up or down on either side. The voltmeter does not register any drop from any window switch. What would make them both fail at around the same time? Coincidence? Could one bad wire cause this? Looked in both kick panels, found nothing in the way of a window fuse.

looked at the online bgb

arrrrrrrrrrrrrrrr

 

Re: RHD Passenger Power Window troubles

going to check what i think is the fuse but here's the thing: when i put the drivers window down it tried then gave up. How could a busted fuse give a gradual failure?

no power at all to either window, with 35*C days coming up. help!!!

 

Re: RHD Passenger Power Window troubles

i think i've blown the fuse as well as the original failure but it's not the kind you can visually check. when they were working, using either switch dropped the voltmeter to the lowest of the blue sweet spot. Indicators and other accessories work as usual. Checked all normal fuses, no worries there.

1. if the p/w relay is in the drivers switch, could a single wire come loose and stop the passenger window going up but keep going down, then blow a fuse and stop both sides from working?

2. i checked the copper arms in the switches, not broken. Could i have bent them too far so they connect up and down at the same time - would this bust the fuse?
after doing this the passenger window went up and down twice, then the drivers window failed after moving down about 2mm and that was the end of power windows.

3. my Radio 2 fuse in the drivers' kick panel is supposed to be 7.5 amp, the fuse in there is 15A. is this a cover up of a bung electical system, or the done thing with a sound system?

4. been suggested that when the voltmeter drops to the bottom of the blue during Window use it means there's an abnormally large drain from the battery. usually i get this from indicators, windows, wipers, locks.
bad alternator/wiring harness?

cheers.

 

Re: Passenger Power Window troubles / wiring stuffs

-Lately headlights are dim and passenger power lock sounds a lot beefier on passenger side so a clean up is in order and maybe new alt with the 3s-fe bracket i'm getting soon, old aftermarket headunit was 200watts, new is 220.

-ive got a theory, originating from my recent head unit install where i did not remove the - battery cable and blew the radio 1 fuse next to the battery. after reading st165-s thread i think the passenger window is too sticky or running outside the guides - making it 1cm forward and ~1.5cm down from where it should be. Swapping switches with the key turned to ON blew the fuse in the passenger kick panel.

looking for the spare drivers side switch. Going to buy a new fuse, finally gonna get an auto scaling digital multimeter and maybe aftermarket window switches if i can't diagnose it.

As for a stuffed relay, does the repair just cover rewiring to a new plug?

 

motors fine, onto switches and wiring

Thanks for the advice
Cleaned and greased both sides, motors are fine.
Spare drivers switch - no luck
Found the circuit breaker in the drivers kick panel, haven't pulled it to check yet.
Testing switches - which pins am i testing and is it for resistance while disconnected from the circuit or voltage/current through the wires to it?

Ground point at the top of the passenger fuse panel. Never been bolted in at least since the engine swap 2 years ago.

 

Fixed for now. I checked the circuit breaker, reset it and drivers side worked fine. Tried with the pass switch, blew the breaker again. Tried with the spare switch, no problems. Both windows work fine and now smoother as i cleaned them anyway.

i think the pass switch was wearing out, i bent the contacts too far, it shorted the circuit, sent me on a wild goose chase for wiring. Success!

thanks for everyones help, pointed me in the right direction real goodly. Hopefully they keep working fine :thumbsup:

Note:
PW circuit breaker is in the drivers kick panel, doesnt matter RHD or LHD.
Passenger window will not work from drivers switch when passenger switch disconnected.

 

hi cheers for the helps, both windows have been fine thru the drivers switch

sometimes the pass switch won't go up, just like the old one. i already rebent the copper contact, cleaned a bit of stuff off.

Anyone willing to post a pic of a good switch with the clearance between copper and plastic on each side of the switch? fair bit of effort getting to them but it could be my answer, instead of chasing a ~$100 switch that toyota aus may not have anymore.

thanks for any more advice.
