Running into an issue where the A/C is stuck on defrost mode and was told to check for a vacuum hose leak in my car.

I found this thing that isn't plugged into anything but don't see anywhere to plug it in... any ideas?

Also, I don't see any hose connected in the second picture, back by the fire wall???

I'm having trouble locating the vacuum hose as well... I don't know what to look for and can't find any manuals or videos of it.

Pic 1 is an electrical connector and pic 2 is the A/C drain.

The mode door is what controls air flow direction. I looked it up and found that this one is controlled by a cable. Take a look at these directions for removal and replacement of the cable. Check the cable shown and see if it is disconnected or broken.

Take a look at this link for a better description and what to do when it is stuck in defrost mode:

Discovered that connector actually plugs in underneath the coolant reservoir.

As for the A/C issue, is all this located in the dashboard or is it under the hood?

Took forever but I got the cable off! That was the issue, it's extremely worn and bent at one end. In fact, it wasn't even hooked around the post!

Hi,

I'm glad to hear you got it fixed. I'm confident it wasn't a fun job. LOL There isn't a lot of room to work.

Regardless, please feel free to come back anytime in the future if you have questions or need help.

Take care of yourself.
