window wont go up

okay my pside window works just fine and so does the sunroof but my dside window will go down with out making noise but it wont go up. when i keep hitting the switch it will blow a fuse or the window lock will pop out. i used the allen to roll it up and i noticed that the wheel had some play in it. i think its the regulator but i wanna get someone elses opinion before i go tearing though my car. i have a 1990 325is i can get parts off of so lmk if you have suggestions.

Before digging into the door, try swapping in the passenger switch.

i already swapped one out of my old car.

update. no dside window activity at all. but the sunroof and pside still working 100% perfect.

Sam- it prob the motor/regulator, if you've already tried the switch. Just swap the whole assmb off the '90

ight the 90 doesnt have a place to crank it up with the allen wrench? are they the same?

[SpecM]

should be...

but I'm not 100% sure
