hey guys well my passenger side carpet is wet but i dont think its my heater core i have heat and no antifreeze smell. Ido hear a sound of warter gurggling after i turn the truck off when using the heat and also when i hit the off button since i have electronic controls i still get hot air comming out with no blower i am thinking blend door any help thanks and i have a 03 f150

 

Hhmmm. Not losing any coolant? Check for windshield leaks or signs of water up under the passenger kick panel. Otherwise keep your eyes on the coolant level....

 

Could be a drain tube for your cowel or the heater box.

 

Im having the same problem...I thought cause it was raining like crazy that was the reason.

 

evap drain tube? you been running defroster? Defroster uses AC compressor, which uses evaporator, which can clog up your drain tube.....

 

yes i do use my defroster alot so how do you fix the clog

 

Find the drain tube coming out of the firewall, and gently blow through it with a low pressure air gun.

 

its on the passenger side firewall, almost right behind the cylinder head, its behind a porkchop shaped piece of plastic

 

My sunroof on my 2003 had the drain tubes clogged and caused the carpet to get wet. I took it to a specialty sunroof shop and they blew them out for $50. Problem went away. They said they see this all the time on all kinds of vehicles.

 

A guy could make a living flushing sun roof drain tubes at that price.

 

For the longest time, I thought gurgling sounds after shut down was air in the coolant lines. Didn't realize it could be anything else. My 98 has done that for ever, since I can remember, for years and I can't get rid of it. Doesn't do it all time, once in awhile. But never goes completely away. I guess it's not hurting anything on my end, just curious why the hell it does that.

 

Thx for that info. Maybe I'll franchise it.
