Jeep Repair: air conditioner, dual climate, jeep cherokee

Question
QUESTION: I had a rebuilt engine put in my 2000 jeep Cherokee in Dec, when I got it back the heat didn't work on the passenger side, was told it was an issue with some door under the dash that regulates the heat. I had been having continual oil leaks with the rebuilt engine and I just got it back today after a week of them trying to find and fix all the leaks in the engine and now my air conditioning blows warm air. Seems to odd to be a coincidence that the air worked before the work and now it doesn't, any suggestions?

QUESTION: Yes, dual climate controls with a digital display

Answer
U have blend air door issue  they are broken at the hinges and the motor will just spin and not move the doors for the hot and cold. The dash will need to be removed and the hvac housing as well split apart and the doors replaced. I do this sorta job on the side for 700 total compared to a dealer for 1300 to 1500. I live in Atlanta let me know if u are interested.
