Hey guys suddenly my passanger side window is not operating correctly. when i switch it to go down it will somtimes roll all the way down no prob or will stop half way, then when go to roll it up it will go only alittle. if i hit the button again to go up it wont but, if i wait a couple of minutes and hit the button down then up it will go up alittle bit or all the way. it also dose this when it pleases. any ideas on this? it also is slow moving
