I noticed this morning after I took my son to school that when I hit the switch to lower the passenger side window that it wouldn't go down, now i'm not sure if it's the switch on the driver side control, or if it's the control switch on the passenger side, or maybe it's a wire in the door, or even because the temp. went down so low last night, could you please give me some direction before I make a wrong decision, Thank You..
