Blend door actuator access.

Hot air blowing from drivers side with AC on

Need help identifying a part

Driver side air will only blow heat.

Why won’t the blower motor run?

I own a 1999 Buick Park Avenue with 90K Original miles. I just moved down to Miami from Annapolis, Md. I recently had a mechanic that I found online come over and give me a free estimate on my AC Unit. I told him that I changed the battery last March. Hot air was coming in on drivers side and slightly cool air on passenger. Prior to changing battery COLD air was coming through Drivers side and HOT air on passenger. This cat tells me the Drivers side actuator (Left) needs to BE replaced as well as the right side actuator. Really? So, I go on you tube and I find video’s about replacing blend door actuators. Then I find a comment. The guy says take off the NEGATIVE cable from Battery and let sit for 10 minutes. Then put the cable back on and this will RESET your car. Well low and behold! My car NOW BLOWS ice COLD air AGAIN but the passenger side gives out (inside vent) lukewarm air. This mechanic wrote up a estimate for $314.00 for 2 blend door actuators and 85 dollars for 1 hour labor to Remove & Replace the actuators. I called him out and said I will look for my own parts. Then I found parts on www.Rockauto.com for a reasonable price. Then I called a old friend and he told me to START from the ground UP and RECHARGE my AC Unit. So I called this guy back and he swore it was the driver side actuator that needed to be replaced. I never called him back because he is just another guy looking to rip off a customer because of their lack of experience. Well, I am NOT that stupid as I used to be a salesman and I KNOW a pitch when I hear one. I just don’t have the tools. PLus I always DO my homework and watch OVER them if I want to use their service. Anyways, My ? 2 U, Sparky. The Air Compressor and Blower motor are fine. Numbers are working at proper gauge pressure on RED and Blue lines. NO LEAKS. Left side actuator is fine.There are 4 ” vents ” across the dashboard. 2 on the left (Driver’s side) and 2 vents on (Passenger side). If you go from left to right in terms of vents, Vent 1 and 2 are blowing COLD air. Vent 3 Inner side on Passenger is the ONLY vent where the lukewarm air, blows out. Vent 4 (Climate Control) seems to be blowing cool but NOT super COLD like the Drivers side. Not sure if the right side is working properly?? Is this A fuse? Should I just RECHARGE the entire AC Unit with refrigerant first or should I replace the RIGHT side (passenger) vent 3 blend door actuator? Heat works throughout the car. Should I also KEEP the RECYCLE button ON when driving my car? Your opinion counts! Thank U

HVAC control temp issues

when i turn the air to the defogger position (front window)i get very low air flow, all other vents work perfectly floor, mix,vent etc the hot and cold air works good everything else works good. The only issue is that the air flow for the defogger position is about 75 percent less air flow then normal

Rear ac isn’t working

Air isn’t coming out of my rear top vents in my suburban

I recently replaced my front actuators on my air conditioner

My heater on my 2009 Ltz (auto control) doesn’t get very hot. I replaced the cabin temperature sensor.
