I tried some jelly, no difference. I don't like the noise the motor is making, so I'm going to have to take her in. Thanks for the tips.

 

spray the window track with some silicone....
thats all mitsu is going to do anyway

 

warranty even though mitsu sucks in this dept.

 

Well, for anyone who may be seaching for this weird issue. I took it to Mitsubishi, and although the mechanic seems to thing it may not be a problem, he ordered me a motor. He doesn't want to take the door panel off multiple times, so he is going to try lubrication, then replacement all in one shot.

 

Well, the final window update...
They replaced my motor, and regulator, and the result was next to nothing. I think it was quicker just because they had the door open and lubed. They informed me that the felt was tighter on that side, and it may break in. But they concluded nothing is wrong with the window, and they won't be trying anything else.

So the short of it... a slow passenger window on an Evo is not unusual and most likely not a problem.

 

mine is a fraction of a second slower on the passenger side but the motor makes no wierd noises

 

my passenger window is slower too on my 06 MR, and if i start putting the driver side window up while i'm already putting the passenger window up.. the passenger window slows down a little more. no weird noises tho.

 

+1 . its too soon for your motor to be having problems so have mitsu take a look at it and remedy the problem.
