I have this weird smell coming from my heater inside the car only when the heat is on kinda smells like mold but at one time my wife said it smelt like something old ac is normal just wondering if there was a cause for it and if there is a fix for it

Any suggestions?

When was the last time you changed your cabin filter?

^ could be it, you know its winter time, and rats do make nests inside the cabin filter area.... we've seen it on here....

Sounds like exactly what you need to do. I bought a cabin air filter from Amazon and changed it and after a week of installation, no more weird smells for me.

Haha... that Fram Air Filter packaging and name reminds me of an old TV commercial for Summers Eve douche.

I ordered the same exact filter from Amazon over the weekend. My car has that strange smell also when I use the heater. I'm really hoping this helps.

Thanks for the suggestions I jus ordered a filter hope thats the cause of it.. Is there any DIY on putting one in?

I think I got a DIY on it is this one the right filter DIY?

Search YouTube. There's a perfect one for you.

Is this the right one for the g35 coupe?

Yes. You really need to learn how to find info. All I did was look at the reviews and it clearly showed people with g35 coupes using it. Also you can find out from the part number which is easily accessible. The DIY video on YouTube is also extremely easy to find. Goodluck

Einszett 1Z Klima-Cleaner AC Odor Remover

If the odor problem is the evaporator the new filter will not help because the air is filtered before the blower sends it to the evaporator and into the car.

I decided to clean my evaporator in case that is the cause of the odor.

I removed the glove box, in-cabin filter and blower motor. I realized afterwards that I could have just removed the blower motor to access the evaporator which would have saved some time.

Here is a picture of the evaporator, you can see dark coloration on the upper right and bottom center area. I was really curious as to what the condition of the evaporator was so I held my cellphone to the air duct left of blower motor to snap the image.





I sprayed the entire can in there and it drained out correctly so I know the drain tube is not blocked.

I really hopes this does the trick, I'm going to do it again in a month or so due to how dirty the evaporator appeared to be.

Update:

Its been about one month since I used the Einszett 1Z Klima-Cleaner AC Odor Remover on my car. I glad to say that the odor is gone and the car smells 1000x's better!!!

Good Information....^....thanks, if SLICK gets stinky I'll know what to do....
