I have a 2002 Nissan frontier V6. Lately, the heater/AC control is a little out of whack. Unless the temp control switch is turned to the coldest setting, it seems like the heater line remains open. If i were to have the problem looked at, what repairs should I be expecting and would you know a ballpark figure for the job? Better yet, is it possible for this to be a D-I-Y thing?

Thanks.
