faulty sensor, broken connection, you need to open things up and have a look. try swapping the external and internal sensors, see it the fault goes to the inside.

so if i strip down the sencer that works and look at how it is connected up then check the faulty 1 to see any cable damage if not sencer is broken how much are these sencers and thanks

Is there not a selector switch on the doors somewhere??

Sometimes it's a simple rocker switch on the door unit itself, sometimes a stand alone key switch located above or to the side of the door etc.

you need to find out the make and model of the door motor,most of these have a built in control board,it could be the pir/the motor/the board, anything could be at fault
