HVAC Condensate Line Location

[Lurker_350]

Hi,

I'm doing some AC troubleshooting on my 2016 GT350 Tech I've owned since new. I can't find any leaks in the engine bay at fittings or the condenser and wanted to use a UV light on the AC drip line - hoping that if there is a significant evaporator leak that it might show up as a UV marker on the drip line.

I'm embarrassed to say that I cannot find the drip line, which is usually very easy to locate on a vehicle. Anyone have any pointers? I found a couple other folks that mentioned the AC dripping directly on the transmission - maybe the drip line ends right above the transmission? I know @honeybadger and @Muligan have had their transmissions out - hoping they might be able to help.

On a related note, the OEM workshop manual says its only 37 distinct steps to get the dash out to replace the evaporator assembly, so I've got that going for me

Thanks all!

I don't recall ever seeing a drain. I looked through the service manual and didn't see a reference to it either.

That said, an AC failure is almost always the coil inside the car that requires removing the entire dash. My car had that and a few of my friends with the earlier cars (15-17) have to get theirs replaced as well.

Found a photo that states the drain is just an opening above the transmission on the passenger side. Figured I would post here for anyone else with the same question. Note that this person was using a can of evaporator cleaner and the tube from the can is what is pictured attaching to the drain hole. I will respond later to either confirm or deny the location.

Just to help you. I used my endoscope camera to get a look in there. Nice and dry and not blocked. Next plan is to decontaminate this area for me.

Thanks for posting that!! I forgot to respond back to this thread since I ended up not having to pull the climate control housing/evaporator out. Never ended up confirming or denying the drain location.

I'm sure your post will help others troubleshooting their A/C!
