I have a 2000 CR-V SE and for awhile now the driver's side front window has been slow to roll up. Well, it finally came to the point that it won't go all the way up..........correction, i can get it to go all the way up if i pull on it and rev the engine at a higher rpm. it goes down no problem, though. I took the door panel off and sprayed silicone spray in all the moving parts (including the rubber side pieces). it didn't really help. What do you guys suggest?
