I bought my 2005 honda accord 3.0 v6 vtec manual coupe at auction. Still dealing with clutch issues. The windows wouldn't work so I took out Master switch and seen mirror was plugged in but window control wasn't. I turned on my key and plugged it in. Window rolled all the way down and wouldn't stop
.
The keys window motor still trying to roll down more. I pushed and pulled button a few times, nothing changed still powering down.
I turned key off and it still kept running for a few secondsto
I unplugged switch and removed. I don't know what to do next should I order a new switch? Need help

 

A few items might cause this problem. The switch, the wiring, or maybe the car has some sort of aftermarket security system installed. The best way to diagnose the problem is with a volt meter/test light and the wiring diagram from the shop manual. You would test powers and grounds at the window switch.

I'd suggest getting the shop manual for your car. I can't remember if I suggested this on your other thread. You can purchase a pdf of the shop manual for your car from automanualsource.com for $22 and is definitely worth the investment.

If you opt for swapping parts, I'm a big fan of u-pull-it junkyards. If you don't have time, skills, or equipment to diagnose, then the investment on replacing a potentially working part is reduced. The risk is the used part is not functioning either.

Alternatively, you might be able to open up the window switch too see if there is any green/white corrosion shorting power/signal to roll down the window. I'm not sure if those switches are glued shut, but it may be worth a shot.
