Did you check your spare tire? Sometimes either it was not tightened down properly or the jack or handle works loose. Since you can't tell where the clunking sound is coming from, you need to start with the basics to zero in on the problem. You might to want to take everything out of your trunk and see if the problem goes away.

clunk noise you hear could be worn cv axle joint. that is if you hear clunk noise on acceleration.

try going to passenger door window switch and reset it by going down and holding for extra 3to5 seconds after window is down, do same to go up, then try doing it with master switch don forget to hold it longer, this is a reset also used on Scion vehicles, hope it helps.
Good luck

Since you can get the door open, half the battle is already won. Yes, open the door, pull the interior door panel and take a look around. Watch inside with a flashlight (towards the rear of the door) as you roll the window down to see if you can see what it's snagged on.

I have a clunking noise in the front of my 06 saturn vue , all front end parts are ok

the cable that drives the window up and down the regulator has broken. common problem. regulator needs replaced

either u-joints, or ball joints

Check the front struts ( shock absorber ) If original or very old, they are doing no good. Also check the front TORSION BAR rubber bushings. In low temps will groan and creak, on up and down motions.
