l have re-placed new motors in both doors,again not working! can l simply re-place doors with ones which have manual windows basically can l just do a simple door swap?

Check the switches andf make sure there is an electric supply.

You have My deepest sympathy.

check the actual regulators. if the wires that move the window up and down are damaged or have dirt in them it will strain the motors and cause them to burn out. This is the usual cause. l work at a hyundai garage. also the switches are a known problem

Swap the car instead, it is a Hyundai and it is CRAP
