Evap drain access on 2017 gt.

[Mustang702000]

Hello all. I guess I have clogged evap drain. Pass carpet wet.Drove a lot yesterday with ac on,found the floormats and carpet wet today,
Looked at the threads dealing with this, and as I dont have a lift or ramps, and a bit sore from arthur, I was wondering if this drain situation can be dealt with from inside the car?
I kinda doubt it,but it dont hurt to ask.
I appreciate ,as always, your help. Best regards, Dave

Suppose it is possible to remove cabin air filter and blow compressed air in that area and clear the drain that way?

There were some older thread from a while back discussing the HVAC drainage. From what was discussed, the HVAC doesn’t have the standard drainage hole or tube through the firewall. Supposedly there is a hole over the passenger side of the transmission from where the A/C condensate exits the HVAC system. Also some have said the HVAC in the S550 is dual drainage too.

I’ve never had the S550 HVAC box apart so I can’t confirm the dual drainage, or where there would be an additional drain.

There is this thread below which discusses the EVAP core extensively which includes pics and shop manual diagrams throughout the thread, including a complete breakout of how to replace the EVAP core. I know you don’t have a current EVAP core issue, but I’m just throwing this your way so you can see what everything looks like behind the dash.
