Nissan Repair: air condition, automatic climate control, nissan quest

Question
why is the front air not blowing cold but the back is? Nissan Quest 2000. We recently had the switch box rewired because the fan switch had burnt on it and they could not get it off to change it. Everything was working fine for like 3 months, now the front air will not get cold but the back will. The car is not overheating and the fan is working fine.

Answer
Marcia,

You could have a couple of things going on here.  I think you have the automatic climate control?  If so, the panel could be doing strange things and not allowing the front blend door to move all the way where the airconditioning is working.  Otherwise, the next thing is the expansion block could be stuck and not allowing the refrigerant to flow peoperly on the front system.  These are the two most probable issues.
