Passenger Power Window Broken

I'm having a problem with my power window (passenger side), which doesn't roll up. Trying to find out the least expensive way to fix it.

Just made a quick call to the dealer. They said it could be the motor, regulator or switch (or any combination).

What would be the least expensive way to get this fixed. Should I take it to a general automotive repair shop or to the dealer? Is this a pretty simple fix, or does it require a dealer's expertise?

Any opinions would be greatly appreciated.

first, what year G20... second, did you try both the drivers control switch and the actual switch on the door to the window... ? try that, if one works the window and the other doesn't, bad switch. could also be the relay wich might be the "regulator" the dealer was talking about, and last, the motor. As always, the most in-expensive way to fix it is the junk yard DIY... then probably the dealer, seeing as it's going to need an OE (original equipment) part which, an independant shop would just order from Infiniit anyways, and then raise the price on you... so, from least expensive to most I would say "DIY, then Dealer, then Private Shop"..but, it shouldn't be too hard to fix your self man... it's one of the 3 things the dealer listed so, if you get all 3 from the junk yard and replace them, viola, working window... ;)
