A/C is on vents blow hot air?

Hi,

From what I am reading, if you have dual climate control, then the system must also be automatic climate control. So, that is what I used for the directions below.

Pic 1 shows the locations. The L and R are left and right sides. Left is the driver's side and the area of concern.

The remaining pictures are the directions for replacing it. Note: Pic 3 shows the section of floor duct that will need removed.

Let me know if this helps or if you have other questions.

Take care,

Joe

See pics below.

Hi,

No problem whatsoever. However, this creates a new problem. Although it isn't dual climate, do you still get one side hot and the other cold? If that is the case, it sounds like something with the duct work has come apart. The cold air comes from the same place, the evaporator under the dash. If one is hot and one side is cold, something other than the blend air door is happening.

Let me know. Also, let me know if the cold side changes to warm if you turn the heater on.

Take care,

Joe

Hi,

That is interesting. It sounds like the blend door motor is working. If you look at the pics above, you will see where I put L and R on two of them. Remove the one that shows R and see if there is anything preventing the door itself from fully moving.

Since you still have air blowing out from the driver's side, it doesn't sound like the duct work is disconnected.

Let me know.

It's unlikely the compressor is the issue. I'm going to mention this to the site owner. He is excellent with A/C. Let's see if he has a suggestion.

Also, just to reconfirm, this doesn't have dual climate control, correct?

Let me know.

I would re-check the refrigerant level because if it is a little low it can cause the system not to work correctly, here is a video to help you:

Please go over this guide and get back to us.

When the A/C system is on for a couple of minutes, grasp the large refrigerant tube coming at the firewall it should be cold. Here is where you should check. Also did you swap out the temperature blend door actuator? Check out the images (below). Let us know how it goes.

Okay, lets check the low side output the as marked above and let me know.

There is the problem, you will need to check the high side pressure of the system to determine if the expansion valve or compressor is bad.

You can rent the gauge set from the auto parts store for cheap.

Yep, you have found the problem, either the expansion valve is bad or the compressor, this is why most repair shops replace them both at the same time. You can try the expansion valve first, but I think it is the compressor that is bad. Here is how to change it out. Check out the images (below). Please let us know what happens.

Good call, let me know how it goes or if you need any help.
