Funny A/c & Heater Smell

[jayr34]

When i use my aircon or heater i get these kind of damp wet smell coming out of the vents.

At first i thought it was the freon but it also comes when i use the heater.

(I was told to change my freon because the gases are now old & could even be harmful, and to be honest each time i use it on a hot day i feel extremly sleepy when i use the a/c)

Anyone got any ideas?

Thanks people.

Is the drain hose from the A/C clogged > mouldy?

Even if that's the problem & it has been rectified, it's common to get a bit sleepy with air cond ON and lack of outside air coming in; due to positive ions being emitted. Some shopping centres do that to people too.

But yes, mould is NOT healthy at all.

I knew it! The whole time i thought i was being paranoid untill i almost wiped someone the other day on the road :\ Where abouts is this hose located & what should i use to clean it?

there was a thread about smelly air vents a while ago

you can buy this stuff at autobarn that you spray in the air intake (at bottom of windscreen) that can clean out your air/fan stuff

Good time to clean the cabin filter too.

In regards to the system being smelly - run the a/c on constantly re-circulate (I'm aware it's un-healthy) for a few days whenever you drive the car - this will help dry any moisture in the car.

Another thing to do is spray a good amount of Glen 20 (or any other available air-con disinfectant) in the front foot wells, leave the A/C to run on max speed, get out of the car (the fumes would make you high) and close the doors for about 5 mins.
