2004 S hibernating for the winter.
There was a bit of a musty smell coming from the ventilation this season so I did some searching and it sounds like my ventilation duct's and AC Evap. need to be cleaned. There are spray foams that can do this but first I need to make sure the drain line for the Evap. housing is clear.
Where is the drain outlet ?
Have you used this spray foam cleaning method before? Any bad side effects?
I've attached a few pictures to help.
Passenger foot area. I'm assuming this is the Evap. housing drain line?
This is the passenger underside just right of center line. I can only stick a wire about 3/4 inch into nipple then it stops like it has hit an elbow? Is this the outlet for the Evap. housing? Any suggestion how to confirm its not plugged?
Since I'm on the front end of the car and drains, what is this drain pipe from? This is back side of right front wheel well. Battery drain?
