Ok here is the deal. I had a almost identical problem. After searching 
through all the wires for a broken wire I became stumped. I checked the 
relay it was fine. I am going to copy some excerpts from my older posts 
about the same topic.


Ohh sorry forgot to mention. If you go to drivers side test the wires
with a multimeter there and get voltage on both sides then more than
likely its the switch. You can take it apart and clean the contacts I
used a strait edge razor. You can try this as well be careful when
opening the switch not to break the housing though use small screwdriver
or something.


Ok I have done further testing with this. If you were to crack open your
handle and take a look at the wires.

|1   ----2    |3
     |4  |5

It would look something like that for the connector between the switch
and the wires. I put numbers by them for ease of reading sake.

1 and 2 joined creates 11.89volts same with 2 and 3. I tested this with
volt meter. Now if I take a wire and join 1 and 4 and 2 and 5 the window
will go up and if I reverse the 4 and 5 wires it goes down. I may be off
on what way I did this but I am saying I can manually make the
connections by hand with the wires. This leads me to think its just a
switch problem.... But if it is a switch problem then why on earth would
a switch from both backseats not work nor switching around the drivers
side switches. This is a odd problem I do say so.

Upside is I know I am getting power and manually creating the circuit I
can make the windows go up and down! This is very exciting right now for
me cause I actually got it to go up and down by creating a circuit! next
step that I am going to do is dismantle the driverside switch and
passenger switch and make sure there is no corrosion in them or some
other funkyness. If this is the case I will clean it and yay.

As to note the drivers side rear window would not work from there but
the drivers door could roll it up and down so I cleaned the switch and
it works now.
