CLimate Control issue

[otang76]

Recently I notice that the climate control on my 2007 Murano S has been malfunctioning. It only cools when I set the temperature at 60 or 61 degrees. I live in Central Texas where the temps right now easily get up to 95 degrees this time of year. When I set the temperature at 62 degrees or higher, the heater is activated. Before, the heater only activated if I set it at 85 degrees or higher. I have tried different combinations but nothing seems to make it snap out of it. Does anyone know how to fix this or experienced anything like this before I take it in? maybe it's a blown fuse somewhere?

Thermostat could be malfunctioning? Low air coolant? Throws out cool air as before, except for the fact the AC has to be on 60 or 61 degrees only.

I guess no one else has had this issue? I was hoping for some insight before I took it in to dealership. Thanks anyways.
