My 2003 coupe driver window started acting up going up and down randomly then just went down and stayed there.

So i replaced the motor regulator with new one. Well still no go tried the reset procedure just for the hell of it as well. So i noticed when I moved the switch got little jolt to the motor but still switch doesnt work. So i think maybe there is a short in the switch. So another 250 dollars later with a new switch in hand. I hook it up and still no go but moving the switch I get alittle jolt to the motor.

I am out of ideas unless somehow the wireing harness shorted out. No clue how that would of happened car had been driven for 3 weeks before that sat for 6 months.

If you have any help please anything tired of randomly throwing money and new parts at it.
