2004 Strange AC Problems

[birdman579]

With the hot weather here in Maryland, the AC in my 2004 is really working hard. Unfortunately, I noticed only hot air coming out of the vents with the AC on all settings. The strange part is hot air is coming out of the 2 driver's side vents, but cool air is coming out from the 2 passenger side vents. It seems as though I have a dual zone climate control that is broken. My 2004 is a single zone with manual controls. Has anyone experienced this? Is part of the evaporator possibly blocked?

Just a suggestion. When was the last time you changed the in-cabin air filter? Maybe really dirty.

More likely your AC airflow controls are stuck, or misaligned, allowing hot air from the heater core to bleed into the vents.

If manual check links. Look under dash. You may have to pull the dash to access them. Possibly the blend door. This is still confusing to me as why the pass. side is cold it should be the opp if if the core is radiating heat. I'll look when i get to work Monday and see if i can find anything on it.

The 2004s did not come with an in-cabin air filter and I have not put one in.

Dual Zone

Was dual zone HVAC an option back in 2004-2009? I wonder if maybe even though I have the manual controls, there are still 2 separate blend doors and the driver's side is stuck in the heat position.
