Trane XL90 4 zone difficulties

I have a newly built house in 2004 and we had a company install a Trane xl 90 furnance. It has 4 zones, right now the zones have some degree of difference as to the heat to settings requested, fine. However zone 4 which is a bonus room (bedroom for 3 boys) above a garage it only at 58 degrees even though it is set at 70 degrees to try to heat it up a bit. I had recently cleaned the furnance filter but what else can I do??

You need to make sure the zone damper for the bonus room is opening.
