Okay, here's the story.... My car never came with power locks. I bought a parts station wagon two years ago that had them. The power locks acted similar to everyone's in the thread (the windows were slow as hell too). Its because all the moving parts built up a bunch of crap and friction. When I opened up all the doors to take the power locks and windows out to tranfer to my Caprice I tired something. With everything still in the wagon I used some motor oil in a little squirter and squirted all the moving parts and sliders. It was as if I put the locks on steroids. I switched them up and down repeatedly as I oiled them and they worked excellent after that. It helped out the windows big time too. Now the whole power locks and windows system is in my Caprice and everything works great, locks all engage in perfect synchronization instantly, even if you just flick the lock switch. Do that, Pop your door panel off and using some sort of lubricant spray all moving parts and sliders (sliders are the big ones in terms of friction). WD-40 will work great, but tends to wear off pretty quickly and you'll find yourself going at it again in a couple of months. Thats why I used motor oil, thick enough to stick around, but not so thick that it makes things worse in the cold.
