probably the motor for the truck release going bad, getting stuck in the open posisiton for a few seconds..
the motor/selenoid part is shaped like a pistol....well kinda like one... there is a spring in there that once the small motor goes off and the drive is pushed into the open postion there is a spring that brings the selenoid back into the closed position so the motor will stop moving... it might need to be cleaned up with some thing like rubbing alcohol so it will not stick... the one i replaced on a 96 contour had a broken plastic gear so i could not fix it, cost of the new part was like $65 about 4 yrs. ago.........
