Does if have the rectangular black impulse push buttons with the metal mounting clips. If so, one of the instant door close contact may be bad on one of the buttons. If you put the car on independent service and the doors close without placing a call that will let you know for sure. Then remove the 305 from 1C button. If the doors reopen it's that button. If not reconnect the 305 wire on 1C and go to the next one until you find the bad one.
