First of thank you in advance for any information.

My first issue is the rear ac blend door: I have done some digging on here and found that the rear ac has issues with the blend door actuator. My issue is it will not divert from floor to overhead and there is a no clicking noise, even when trying to switch from floor to overhead and back. I have used both controls front and rear. I am going to switch the actuator first to check and see if that fixes the issue. I get plenty of air on the bottom and through all ranges of heat and cold, and selecting the air flow rate.

Second issue is air flow change to floor or defrost upon acceleration: I'm pretty sure after checking on here it is a vacuum lose somewhere. Just wondering if there are any main culprits to look for, or how to go about looking for it under the hood.

Thank you.
