2002 grand prix. Heater blows cold on passenger side. Driver side and two middle vents blow hot, the other two vents blow cold.

ether the blend door actuator is bad or the climate control module is failing. most likely the blend door actuator. would have to pull most of the under dash out to get to it to replace it. not fun at all.
