Having an issue with condensation/moisture dripping from underside of dash. I know I need to check the drain tubes. But, I don't know exactly where to look in the interior and how to get there. Is it similar to replacing cabin air filter?

 

The drain tube is not in the interior, it is located in front of the firewall, I wanna say more toward the passenger side. You need to get under you car and look. Please use a lift or jack stands for safety. Not just a jack. Some others have mentioned that techs sometimes plug that tube with a screw so they are not dripped on while working underneath your car. So, check to make sure it's not plugged.

 

Is there not a tube that runs on the interior? Where do I need to look for source of condensation inside the car then?

 

possibly from the sunroof drain tubes.

 

of coarse there is a drain tube inside.....if you peel your carpet back on the passenger side of the car in the middle you will see it.....your drain line is clogged see if there is a bolt in it looking from underneath your car...if not you gotta have the line blown out...dont wait on this....the water that was dripping into my car fried my pcm....in turn that fried the ignition pack...my car was at the dealer for two weeks getting fixed...it was all covered under warranty...

 

Absolutely! If you want to lie awake all night, read this thread:

Get it checked quick, it cost about $3500 in parts alone (list price), not to mention the countless hours of labor due to mine draining into the car/pcm, luckly I'm still under warranty and they covered it.

 

 

Already read the thread.

I checked the tube in the interior and there doesn't appear to be a clog or bolt there. How can I go about getting it blown out?
