blowing cold heat on the passenger

A door/blend panel isn't working right I guess , If you're lucky the problem can be seen without pulling the dash apart

Why do we continually get questions that have already been answered a thousand times? Search for your problem in "Search Questions" and you'll get more information/advice than you need..... You likely just have a defective actuator on the blend door that operates the passenger side; it's likely behind the glove box.

Yep common Chrysler problem.
