Narrative:

While taxiing to gate first officer contacted ground operations for our on-ground call. They notified him that our gate had been changed to the next gate. We had been given gate # on our in-range call; but they now changed it to gate #. There was light rain at the airport necessitating the use of windshield wipers. These would occasionally freeze in place; which is common with the 737-300/500 aircraft; so we would turn them off temporarily; then turn them back on as needed. Upon arrival at the gate there were no personnel to marshal us in. After two calls to company by the first officer and a 2-3 minute wait someone came over and began to marshal the aircraft in. We both confirmed the safety zone was clear and at this point turned the wipers on and left them on. I taxied slower than normal due to the rain. As the marshaller brought the wands together; we felt a slight bump. After shutting down the engines we looked out to see what had caused the bump. We later learned he had used the wrong line to stop us; bringing the aircraft too far forward causing the #1 engine to impact the jetway. The gates had belonged to another carrier and the marshaller was unaware that our aircraft were to use the stopping line further from him. He may have had some difficulty noticing the two different lines due to the rain.
