2006 LS Vibration 68-72 mph

[MFLSJHS]

My Lincoln LS has a moderate vibration right around 70mph. you can feel it in the floor and the wheels shakes, the car has new good year tires that were balanced by Lincoln Mercury. It had no vibration after the tire balancing, it started about 2 months after. any ideas?

also my drivers side window will go down and up holding the button and will go down auto but it wont come back up by it self you have to hold the button. this just started the other day

did they use clip on or stick on weights? if they used stick on weights it's possible that they fell off. i suppose clip on weights could come of too but more common for the stick on style to fall off. just a thought

Did you hit anything hard that could have slightly bent the wheel?

Try resetting the window by holding the up button until it goes all the way up and stops, continue holding the button for about 2/3 seconds, see if that helps.
