hello i had a problem with my door locks got a new master switch all works greatwith the key on , but as soon as i start it ,the driver side window will go up or down one time then stops working all other windows and locks work , i put the old switch back in and works as it should except the locks , I have tried two new switches thinking the first one was defective , both act the same ,
