Problem: drivers window wont work. and the doors wont unlock or lock with the remote!

well it started over xmas break the drivers window wouldnt work (all others do) maybe for 5 days then started working again!
i thought nothing of it and all of the sudden it happened today again same thing. when i got home i was going to get something out of the back seat and hit unlock on the keyfob twice to unlock it and the lights flashes but no "unlock noise" so i hit the button about 10 times and nothing. it doesnt un lock or lock the doors, the lights flash and horn sounds but noting happens.

does anyone have a clue what it could be?

thanks in advance!

Something like that happened to me after battery went dead while fitting my dvd system.
Drivers window was stuck down, doors wouldn't lock/ unlock, check engine light was on.
I read somewhere to take off battery cables, touch them together for 5 seconds then leave for 5 minutes then reinstall cables.
Sounds bizare but I tried it and low and behold everything was back to normal..
Give it a try !

I had something like that happen to me right before Christmas. I had a power inverter plugged into one of the cigarette lighters, and the remotes would not work at all. As soon as I unplugged it, everything was fine.
