Hey everyone! I've got a 2013 EB CC FX2. This past week, I've heard a little gurgling/water sound come from my dash. It goes away after a little while, but it makes me wonder if my AC drain tube is clogged.. when I get home, I see that one of the drains is working correctly. I see a puddle of water behind the front right wheel. I heard there's another tube in the engine bay that could be blocked... does anyone know if that's true?
This is what I see when I get out at my house,
This is a pic of the passenger side of my engine bay. Is that opening next to the tube my second drain tube?

 

There is only one discharge port for the evaporator. The symptom you describe tells me you have an air pocket in your cooling system, your hearing bubbling inside because the air pocket is resonating thru the heater core, typical after any kind of cooling system repairs or lack of maintenance where one would check and top off the degass bottle, bust a hose or loose coolant at some point?

@Rnlcomp - good point. I don't believe I have a leak in my cooling system, and I haven't done anything in regards to repairs. Is there a way to "burp" the system?

 

Back in the day, we would park the vehicle on an incline, vehicle nose up as high as you can get it, fire the engine up and remove the degass bottle cap, let the vehicle run at idle until it's fully warmed up while observing the fluid level in the bottle, what that does is put the fluid entry level above the heater core.

If there is an air pocket, that should remove it.
