The air conditioning smells like dirty socks in my 08' 150??
Is there a cabin filter that needs changing?
If so can someone point me in the right direction?
As well, has anyone used "AC Pro" how does it work?

Thanks

 

Most likely there's mold built up on the evaporator from the condensation on it. Only way to get rid of it is to drill a hole in the case and spray a cleaner on it or take the evaporator out and bleach it (might as well replace if you're gonna take it out).

 

What would the cost of replacing the evap be? and does this model have an cabin filter?
Thanks

No cabin filter. Cost will probably be quite high as you would have to have the a/c evac and recharge and then pull the dash to remove evap box

 

... There are certain foaming products that clean the evap. The spray then drains out through your condensate drain that leads under the truck. You spray it in through your AC vents... I've sprayed Lysol in mine last year and it seemed to do the trick... Your basically smelling wet dust and dirt sucked into the coils fins... This is what sucks about not having a cabin filter...
I've seen a few threads of some guys modding theirs to accept a cabin filter on the Internet.

 

I have an old classic that sits for long periods of time. It has a similar problem. I exposed the coils and bleached them once. Took all weekend, and the car smelled like laundry for 6 months. Someone else suggested to just spray Febreze into the intake and it worked! Smells better than bleach, too.

 

Mechanik, thanks this sounds reasonable! Now for the next stupid question where is the AC intake? The air box in front of the windshield??

Thanks

 

I had a buick that had that very problem. Took the majority of the interior duct work out, and the cabin filter and blasted the system with Lysol. Make sure the condensate drain is clear!

 

have you checked the drain line from the evap? It's how the water drains from the evaporator and is what leaves the water dripping under your truck. These get clogged up and don't drain, giving you that musty odor and mold.

It can be cleaned with a wire. I've also seen people used canned air to blow the obstruction clear, though it does end up in the heater/ac box.

Give that a look and see if that helps.

 

That's where it is on the DeLorean, and I assume it's the same on the Ford. A bit obvious once you think about it, but crank the fan on high, make sure the system is NOT on recirculation, and don't spray too much at once. I think the idea on the last piece is so the spray stays as a mist so it can be sucked through the system. After the first time, I left the doors open so the car didn't smell too much like Febreeze!

It's a cheap fix and if it doesn't work, you can move on to the other options.
