Subaru Problems? Ask a Mechanic for Answers ASAP
Hi , yes there are 4 drains one at each corner of the car,there also is a evaporator drain that sometimes clogs with spider webs and fills the case,when this happens the heater case will fill with water then drip onto passenger floor.To check if either are the problem we can try two simple things, to check if evap drain is clogged run vehicle with a/c on if drain is not clogged you should see water dripping under the vehicle,to check sunroof drains for proper operation open sunroof fully open both front doors and while standing on either sill pour a cup of water into the drain channel you should see water exiting from the area of the mudflaps in the front and rear from each side,let me know what you find ,I'll await our reply,thanks
Thanks Pam,Tamaz is a combo of my first and last name but been told this is a Spanish version of Thomas,depending on you location you may or may not get a lot of water from the evap drain,if you live in a area that is hot/humid this puddle forming under your car can be quite large, being from the Northeast where it is cooling down some you may only get a spattering, the A/C job is to remove moisture from the air to cool it so that drain is essential to being clear.
Pam, also I would like to mention if this drain is clogged it is usually very simple to free, blowing compressed air though it will free the clog,other than the 2 things I mentioned it's possible the windshield may be leaking then following the pillar down and soaking the carpet, have you recently had a windshield replaced?
You need a blow gun that attaches to the the compressor hose first and there are 2 ways to get at the hose the easiest would be from the engine compartment ,the hose comes off the firewall just below the frame rail blow the compressed air into the hose to free the drain,if its easier for you you can also get at the hose from underneath
Your welcome Pam!
