I guess to leave it alone or not may depend on where the door is. Is it stuck in recirc, or fresh air? If it is stuck in recirc, you will fog up much faster in cold weather, as you recirculate warm moist air against the windshield. Summer, not as big a deal. If you can manually move the door, I guess you could put it where you want it.
Personally, I hate anything broken and it would kill me to have something broke in the car.
According to ALLDATA, it pays .9 hour. So, you can expect to do it in an hour and a half or so. It pretty much says to remove it, and install a fresh one. The actuator will have a shape that matches up to the door, so no rocket science should be required. ALLDATA also says that after it is done the system will do a self calibration, after disconnecting the battery, and it takes about 13 seconds.
Personally, I would do it and be done with it.
