air vent not working right
i just recharched my A/C. well i turn it on and it works fine, its just that it is always coming out the defrost vents. and then i hit a bump in the road and then it will come out at my feet. and eventually out through the front vents. im thinking the air valve is not workin right. i need some help here.
