My issue is the driver's side is blowing out hot compared to passenger side. It isn’t really hot, but it is only cold when it is dark, raining, or not that hot outside. It seems as if the recirculating button isn’t working on that side.
I have done so much reading online and the only things I can find would be, the system needs charging (I checked it, and the Freon pressure is perfect) or the blend door actuator. I bought a brand new one and replaced it even though when I ran self-diagnostics (holding recirculation button while pressing rear defrost button 5 times while key is turned to, on position) it did not give me any DTC error.
After swapping the new part out, I ran the self-test again and it gave me error code 3. So, I disconnected and realigned the blend door actuator to the correct position and ran self-diagnostics again, this time no error! So, I thought it was fixed.
Of course, being my luck, the A/C is still the exact same, blowing ice cold out of passenger and warm to cool air out of driver's side, depending on temperature outside.
The only thing I have noticed, even before replacing it with a new part, when I press the Max Cool button, the blower does not seem to blow any harder like it used to before it messed up.
I read something about recalibrating the blend door after working on it, such as removing HVAC fuse or disconnecting battery. I couldn’t find anything related to my model, but I figured the self-diagnostics would have calibrated it as well though.
Freon is perfect range and replacing blend door has not fixed the issue. The defective/original part didn’t display any error during self-diagnosis, but I decided to replace it anyway because the only thing I can find online was the blend door actuator or low-level Freon and the Freon checked out perfect. I can see it moving right, the self-diagnostics test and it does not display an error. Only other thing I noticed is that before it started acting up (it would quit working temporarily until it completely stopped blowing cold out of driver's side) was when I pressed Max Cool, the fan bled much harder but not it didn’t seem to do anything different.
If anyone has an idea of what to try or exactly what might be causing this issue, please I would appreciate any advice at this point. I live in Alabama and this month of August is going to be even hotter than the rest of summer. So, I need to fix this ASAP!
