musty smell

i try tracking this odd Oder in my cab ,i keep my inside free of any clutter. i Vacaum it weekly and clean my husky mats when needed. its not my cabin filter either its coming from my defroster so i been running it with heat and middle blower speed. no leaks inside of the cabin and almost positive no coolant leaks? anybody have and suggestions?

 

If you’ve checked your cabin air filter already, what about upstream of that, the gutter that feeds the air to the filter, underneath the windshield cowl, maybe that has some debris or dead crap in it that’s causing the smell?

 

Mildew inside ducts. Do you ever turn recirculate off to get fresh air through the ducts?

 

If you are in a high humidity area, you may have a clog in the drain for the condenser. I think it's pretty common for algae to grow and clog it.

 

that area is always clear of debris plus my truck is in the garage?

 

do you have a location were i can check?

 

My tundra has that smell when using AC, which the defrost setting uses. Try and switch the AC off about a minute or 2 before you turn off the truck to clear the ducts out. At least this is what I’ve been told

 

i only use the ac in the summer when it hot not very often. i have been running the defrost button on medium heat. so yesterday after i was running and stopped at the store for about a hr. turned the tuck back on and i had some moisture about 2" on the windshield then it went away i know that the problem still exist

 

I have a 90 lb Chocolate Lab so my truck smells like cheesy ass no matter what I try. Sorry, not helpful. Just venting my frustration.

 

I've used this technique in the past, works great. Only thing I would do different is to definitely leave all the windows open before you spray. Hope this helps.

Maybe it’s laundry day!

Anytime I notice a Bad Smell there’s only 2 possibilities.

1. It’s coming from my Pup or…….

2. The most probable cause: My Spouse.

 

Sorry, I don't know where the drain is.

 

don"t let her read your post thanks

 

Guess I shoulda been more specific and said: Husband. p.s….especially after eating Mexican food.

 

Was going to say.. did you shower today, OP?

 

thanks i will try this and also find the drain after i deal with my leaky hot water ugh

 

You ever find out what was causing it?

 

Sometimes people spill stuff that the carpet soaks up. And it looks clean, but it's moldy under.

Or coffee with cream spills, then the milk on it goes rancid under the carpet.

Could it be under the carpet somewhere.

Feel around for damp spots
