Nasty Defroster smell

hey, i've noticed this since i boutgh my pickup. everytimei turn the defroster on my cab smells like a combination of dirt and ass. but only when its on defrost. Any Ideas?

 

In cabin air filter???

Then again it's only on defrost, idk.

 

...and its a first gen

 

ahh sorry... should probably read next time.

 

any smell in max a/c? and is the temp blend door in warm or cold? and if you move the temp blend door does the smell change?

 

never have too nasty of a smell when i turn on the A/C just a little blast of usual AC smell when i first kick it on. with the defroster its always stinkin'

 

What i've done was run the A/C full on with the FRESH AIR button on then have a friend spray an odor neutralizer into the air intake vents at the back of the hood as you switch through each setting-vent/floor/defrost that way EVERYTHING gets a dose

 

i'll give it a shot

 

Ozium works well to get that moldy sock smell out of vents.

 

very true, agree 100%. but also would recommend checking your a/c drain just to much sure its not plugged or blocked.......if blocked could cause the moisture to stay in the system and cause that usual a/c stench. just an idea

 

i had that smell in my 1st and 2nd gen tacoma i like the odor neutralizer idea to!

 

true, true.

 

My truck stinks when I run the windshield wiper fluid with the air on. The air by itself doesn't smell (all of them are fine, defrost/ac/regular), but once i turn on the fluid, ohhh man it smells. Is there a way to "febreeze" that?

Yes. Hijackin the thread.

 

did that mist then come out of the vents on you, ridgerunner, while you were sitting behind the wheel?

i caught a mouse dead this summer, gotta make sure before i turn heat on this week its not even close to there, did not notice any with A/C this past summer so might be good to go idk

 

How did you unearth this 12 year old thread?

 

i searched for ozium, saw an active member ridgerunner still around!
... now to see if he recalls this or not

 

Where was the dead mouse? You don't use your vented air / blower ever? The HVAC systems in our trucks are super simple - I can't find it right now, but there's a good write up on cleaning out the AC evaporator. That's enough tear down that you'd be able to clean out most of the vents. Here's the benefit of doing that too, ridding yourself of the garbage that builds up. This is what I found:
