die hard

2015 gmc terrian the window goes down using the switch but wont go up using the switch . i put 12 volts right to the motor regulator goes up and down fine .but wont go up with the glass hooked to regulator ? if i pull up on glass it goes up slow you can here the motor struggle . with out the glass hooked to regulator glass slides up and down smooth . both regulator and glass work smooth but just not together ? ive tried keeping bolts that attach glass to regulator loose thinking its fighting its self and still wont go up? i grabbed a hold of regulator with my hand as it going up try to stop it has more power than i can hold back .either any way i try it wont work off switch ? im lost looking for some advice hope some one has dealt with this problem before and can help .thanks

update after messing with truck for little while cleaned all the grounds still no luck .turn out to be a fuse ? well looks like i learned something to day .you would think a fuse would cause light to go out not dim .

so here my problem my right side head light is dim ? when light is on low both hi and low are bulbs are on but high is very very dim and low is little brighter but still dim .same with left side both bulbs are on .when i unplug right side head light only one of the bulbs are on on the left side ? its got me puzzled hoping some has had similar problem before and found a fix to this problem ! truck is a 2001 .thanks hope you can help

yes. the motor was good had to buy hole unit could find the sensor seperate

i had to replace the who;e encoder motor assembly ($125) i couldn't find the sensor separate even from the dealer .the motor worked so blame the sensor

i cant seam to find the proper name for this part on my 2001 chevy 8.1 with Allison transmission it sits on the side on the transfer case electric shift assembly .has a plug with 6 terminals and looks like the brain/module for the potion transfer 2 .4hi. 4low .have the service 4wd light on in dash .truck is stuck in 4wd low .lights on switch are off they turn on when truck first starts then they go out ? i replace switch ,fuses are good so looks like i have to start throwing parts at it .i called the dealer they only have the whole shift assembly and had no listing for this part .anyone know a part number for this or proper name so i can google it ? thanks

THANKS ! ill give that a try . pisses me off i should of kept the encoder when i returned my transfer case core few years ago.

so i got the service 4wd light come on my 2001 2500hd 8.1 .i switch the truck to 4 wheel low and is now stuck in low . the lights on the 4 wheel selector switch are not lite up .they do lite up when i first turn the key on .what i've tried so far is discontented battery for few minutes check atc fuse is good..replace the 4wd selector switch .cleaned the grounds on frame near cab mount .check wire connections to to transfer case and front differential .i replace transfer case few years ago with a GM rebuilt .im lost hoping someone else has had same problem can steer me in right direction on they have done to fix my problem
