I swapped all relays and fuses and problem remains.
When I put switch to down, there is a click from around the fuse area under the steering wheel.
I read in another thread that the clicking noise is likely the relay, power is going to the relay but not to the window motor. It was suggested to check the wiring and to clean motor contacts. In my case the problem is for both windows-what is the likelihood that both motors would have lousy contacts at the same time. Also, if I press the switch down for 5 seconds the window DOES go down-on both sides.
Further checking of similar threads suggests the BCM auto down has crapped itself. I wonder if it possible for home user to reprogram it? I pulled the bcm fuse to no effect.
*edit SOLVED*
I solved issue by following reset pcm procedure.
Get engine to running temp
Turn ign on
take out eng/cont bcm fuse under bonnet
wait 20 secs for dash to beep at you
ign off
replace fuse
(then follow procedure for idle learn i.e. put in drive for 5 mins, put in idle for 5 mins, turn off 30 secs)
I found that this reset the BCM and windows issue resolved
I think last time I had the ign off and pulled the fuse, not the procedure above
