Electric window

My drivers side window hasn’t worked properly ever since buying the car 2 weeks ago. On the first day I managed to get it working for an hour just by whacking the door, after that it hasn’t worked. I originally thought it was the motor as the relay clicked when operating the buttons however when directly connecting a battery to the motor it works just fine. 
 

when turning the car on ( if window is in the up position) it will automatically retract all the way down. The switch is a bit dodgy as when pushing the button down it doesn’t do the clicky thing, but if doesn’t effect the way the window operates I am fine with leaving it how it is. I am out of ideas and am just wanting to ask before I go buying new parts that might not need replacing. Anyone got any ideas?

Dismantle switch and see what is broken inside it.

By "dismantle switch", I mean pull it out of the door trim and COMPLETELY DISMANTLE the switch. Pull the plastic casing apart and look for dirty/broken/burnt contacts, pivot points, snapped wires or solder joints, etc etc etc.

Beyond that, you are starting to get into the realm of needing to investigate the "amplifiers" that control the motors themselves, because these have electronics inside them, with 30 year old shitty electrolytic capacitors that are approaching or past EOL.

I have checked the switch and I can’t see any bad solders, just some glue like stuff. Would it still be possible that it’s the switch even the though when activating the button it sends power to the motor?

 

upon further inspection I have discovered that power is constantly going through one the wires while the other one only get power when I activate the button

Have you taken the switch to pieces? I mean, pry open the plastic clips that hold it together and LOOK ON THE INSIDE?

Yes, I can’t see anything wrong with it but I am not experienced in this sort of stuff so I can’t say for sure that it’s fine

I took apart the switch and the plastic was very brittle so it sort of just fell to pieces. I cleaned it all up and priced it back together the best I could and will test it tommorow. If it doesn’t work I will just give up and buy a new one

      I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed

      Recommendation for engine oil funnel spill free

      By MBS206 · Posted

      I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.

      Fuel Pump Control Module & Dropping Resistor

      By EndZee · Posted

      Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
