i have a 97 sedan deville and my passenger side power window only rolls down i have power to both sides of the switch and motor so i figured motor was bad i replaced it still same problem is there a relay or module that controls that

 

first of all
what works
does the driver side go up and down
does the back seat go up and down
if so can u control the passenger side to go up and down from the passenger switch

i am sure its a switch problem u r having
if it goes down it should go up
the switch just reverse the power and ground to change the direction of the motor

 

all others go up and down ive tried it from driver and passenger side the power switches like its suppose to at the motor the one thing i guess i havent tried is if the ground is switching

 

there is no ground to say its a module that controls it

ok this is how it works say the driver window motor wires are dark blue and light blue

ok if u put 12volt to the dark blue and ground the light blue window goes up

if u put 12 volts to the light blue and ground to the dark blue it goes down

i am not sure these are the colours of the wires

 

if ido this and it works which im sure it will where is my problem .weredoes the driver and passenger switch come together because i have the same result from both switches thanks for the help

 

mostly likely the driver door switch
but if u test the wire going out of the switch in the up and down position u can tell if the switch works
should check passenger side switch as well

 

i pulled the driver door switch and found a computer board ties all the switches together im pretty confident thats my problem ive ordered a new one thanks for pointing me in the right direction i appreciate it
