Do you feel your way around from underneath to clear it ? Or head dive in from the top ? Probably need tiny hands either way...Took me awhile to find this - ref pic - someone posted
As viewed looking up from the engine bay at the firewall
That sounds like another piece of genius engineering.
What exactly am I looking at ?
The $2700.00 was probably them pulling the dash, that wouldn't be required for a blocked drain (I wouldn't think) and I'm not sure how to reach it either ? but might have it up on a lift and just "feel" for it ?
Is this when you know the transmission is hot enough to check the fluid level (with the Fitzstick, of course)?
Yeah, it didn't rain for 5 days and it still got wet carpet when the A/C was on. Everything on the Firewall is dry, carpet, everything !
Being that this is on the Passenger Side, I am assuming that there is still a clog in the drain, the problem is they most likely shot it with shop air - (engine bay - in)I'm having this issue again. I had posted about getting this resolved a couple of years ago at AC condensate. | 2019+ Ford Ranger and Raptor Forum (5th Generation) - Ranger5G.com . It was resolved for a while, but it's back.
Unfortunately, the fix that worked last time was unsuccessful this time around after taking it to a local shop. I was told by the mechanics that they cleared the drain, and that it had been partially clogged though I'm still getting water on my floorboard.
In the picture below, I've got my carpet pulled back on the passenger side and I am pointing at where the water is flowing onto (which is on the sealant that the factory has put right near the transmission tunnel on the left of the passenger floorboard when facing the glovebox of the interior). It's a warm and humid day here in South Florida so it didn't take very long for me to be able to spot the water flow with the AC on at full blast. If it's not raining tomorrow, I plan to take apart more to see if I'm able to spot where exactly it's dripping from. I know that my issue is not a leak from outside, as I park in a covered space, and I was able to generate the conditions necessary for water to appear - turning on the AC at full blast.
Thank you for the suggestion! I just ordered a borescope on Amazon and plan to explore this further once it comes in later this week. I will provide an update once I do.Being that this is on the Passenger Side, I am assuming that there is still a clog in the drain, the problem is they most likely shot it with shop air - (engine bay - in)
This helps clear the clog, but eventually the debris will flow right back into position to clog it again. I have a feeling you have a piece of foam seal sitting in the drain pan, that is near impossible to remove without pulling the HVAC box out.
I would pull the Blower Motor out and snake a Borescope into the box to see the drain pan.
The only other spot is the AC Lines themselves dripping down to the floor and gravity draining onto the Passenger floor.
Being that the Leak Flow is coming from the Firewall, I suspect that its the Drain Line
Now I am guessing here buts its worth a try, and that is fish a borescope into the box, you should be able to see the drain pan, and if you are lucky, you can also possibly fit a vacuum hose in there to try to suck it up.
A great vacuum for this would be an Air Vac with a thin hose along with the borescope.
Use the Scope to guide the Vac to it.
Another option is a pair of mechanical fingers
I do not know for sure this will work (Room) and if you can even see it, but it beats pulling the HVAC out.
So, what I think is happening is that the Drain is clogged, the condensate is slowed down and is gravity dripping down the cabin side of the outlet, down to the floorboard or the pan is filling up and overflowing at the seam of the pan to the housing.
A bit of a task but I feel is a doable successful task, depending on how much you can see with the scope.
I think you should have good access from the Blower Motor, down the tunnel to the pan
This is a rotated pic of what the drain looks like from the Engine Bay, it's above the Bell Housing
so this brings in another possible and that is the seal (housing to firewall)
I do not know how much access you have to this spot, but you may try applying some sealant to the bottom of the outlet tube to prevent backflow back into the cabin.
This is a borrowed pic, so I am only going by the pic, I do remember getting a look at mine for general knowledge of location. It is hard to see. But its dead center of the dash for a reference point.
Today I took out my blower motor and ran a borescope camera as far as I could down the AC system, and was able to snap a few pictures. Unfortunately, they are not very clear, and I was not able to see the drain area or a piece of foam. I'm attaching what I saw. I also discovered that my driver side is soaked as well - so this issue is actually both the driver side and passenger side being wet. The driver side is much more wet than the passenger side. Rear carpet is dry.
If it is condensation dripping off of the condenser lines, then the drain has nothing to do with your problem. Ford says to wrap the lines in insulation, or reposition the existing insulation.
I'd wait on the jeep. The scuttle but is, there going to 86 the whole Chrysler /Jeep line. That or sell it or do chapter 11 !
Really, that is what I call poor engineering.
