New member, 03 durango r/t wont switch from a/c to heat
 

I have an 03 r/t durango, problem is it wont switch from heat to a/c. I took the bottom blend door motor off (dual climate) it rotates only when going to heat. It wont rotate when I go back to cold. Not to entirely sure where to go from here. Anyone had an iaaue like this and also have a solution? Main controls bad or blend door motors? Wouldnt think both would be bad?

This is her. About to turn 120k miles.

If it only turns in one direction, it's likely bad.
