Hi! I am new in this forum, my parents in law gave me a 2007 Dodge Nitro and I just started to use it. When I put the heater to defrost the front window heats only in the passenger side and the other side brings cold air. If I put the heat to heat the passenger and driver side or the feet the heat heats a little bit to the driver side but tu the passenger side gives much hot. I want to try to fix it and I don't know how. Help me with any information please!
