Weird smell after I use the defroster

[bay_area4runner]

Hey guys, recently I've been noticing that my runner leaves a weird smell in the cab after I use the defroster.

It happens every time after I turn off the truck and let it sit for a while, I typically use the defroster in the mornings for my commute so when I get to work I turn off the truck and go off to work, but lately I've noticed a weird muggy smell after I get off of work.

I tried using one of those charcoal bags that absorb the smell but nothing happens. I know it's the defroster because one day I didn't use it and when I got off work it didn't smell at all. This smell gets really bad if the day ends up being warm, when I get to work it's usually colder so the windshield gets foggy so of course I use the defroster

Does anyone have the same issue? Or similar issue, I know I can't change the cabin filter since the truck doesn't have one so I'm open to any suggestions or solutions, thanks

Maybe check and service this> http://www.toyota-4runner.org/3rd-gen-t4rs/113266-cleaning-blower-fan-write-up.html

I have heard people having odd smells that end up having to do with the blower fan.

Good luck.

A Woman Gets Revenge On Her Ex-Husband And His Young Girlfriend

After 37 years of marriage, Jake dumped his wife for his young secretary.

His new girlfriend demanded that they live in Jake and Edith’s multi-million dollar home. Since Jake had better lawyers, he prevailed. He gave Edith, his now ex-wife, just 3 days to move out.

She spent the 1st day packing her belongings into boxes and crates.

On the 2nd day, she had two movers come and collect her things.

On the 3rd day, she sat down for the last time at their beautiful dining room table by candlelight, put on some soft background music, and feasted on a pound of shrimp, a jar of caviar and a bottle of Chardonnay.

When she had finished, she went into each and every room and stuffed half-eared shrimp shells dipped in caviar into the hollow of all the curtain rods. She then cleaned up the kitchen and left.

When Jake returned with his new girlfriend, all was bliss for the first few days.

Then slowly, the house began to smell. They tried everything- cleaning, mopping, and airing the place out. Vents were checked for dead rodents and carpets were cleaned. Air fresheners were hung everywhere. Exterminators were brought in to set off gas canisters during which they had to move out for a few days and in the end they even replaced the expensive wool carpeting. Nothing worked.

People stopped coming over to visit. Repairmen refused to work in the house. The maid quit.

Finally, they could not take the stench any longer and decided to move.

A month later, even though they had cut their price in half, they could not find a buyer for their stinky house. Word got out and eventually even the local realtors refused to return their calls. Finally they had to borrow a huge sum of money from the bank to purchase a new place.

Edith called Jake and asked how things were going. He told her the saga of the rotting house. She listened politely and said that she missed her old home terribly and would be willing to reduce her divorce settlement in exchange for getting the house back.

Knowing his ex-wife had no idea how bad the smell was, he agreed on a price that was about 1/10th of what the house had been worth, but only if she were the sign the papers that very day. She agreed and within the hour, his lawyers delivered the paperwork.

A week later, Jake and his girlfriend stood smiling as they watched the moving company pack everything to take to their new home...

Including the curtain rods.

Defroster turns on the AC.

AC on = condensation in the heater/evaporator core.

You are smelling musty build-up in the heater core... Either turn off the defroster a mile or two before your destination (if possible) to dry the core or clean the core using some sort of disinfectant (lots of choices, no personal experience).

Good luck!

Nope doesn't smell that bad.


It's a weird muggy smell, only happens when the defroster is on. I'm gonna try to clean the vents but I'm not sure where the air comes from? I know the heater motor is under the glove compartment but where would I spray the disinfectant is my next question
