Hi i would like to know where is locate the evaporator of air conditioner because I want to clean it or if exists a tutorial in this forum to do it?

The reason is that my a/c system did not have a filter and I think the evaporator is really dirty.

Thanks for attention.

 

I don't think there is a tutorial here for that. It's buried deep up inside the dash and will be a major pain to get to as it is mounted above the heater core as well. You would be looking at major surgery under the dash to get to it.

What makes you think it is really dirty (other than having no filter installed)?

 

When I turn it smells bad and the amount of air that coming out from the vent is little like I felt before, thats my reason I think cleaning the evaporator fix those problems, Ive cleaned evaporators of a/c systems but i cant find the evaporator of my car I saw it in my manual parts hhr and looks like deep, the costs to clean it in a auto machine shop is around 120 dlls and I just want to save some money.

Thanks for help and attention.

That would be your cabin air filter that probably needs replacing...

 

Ahhhh well that clarifies things a bit. Like badassbowtie states, you likely need to change the cabin air filter (accessible via opening the glove box and releasing the latches so the door hangs down a bit - see the info in your manual).

And if the nasty smell continues, head to your local auto-parts store and pick up a spray can of the deodorizer/sanitizer made for cleaning and getting rid of the nasty stuff in the heating and cooling system. the store staff will point you in the right direction, and give you instructions on how to use it.

Running your a/c periodically (maybe twice a month) for a few minutes also helps keep the odors at bay, and is actually good for your a/c compressor.

 

FWIW the evaporator should be inside the car, and up near the firewall, near the center of the car...I only say this because of where the drain is located.

 

Whopper and Badass.........

I think when he referred to the a/c not having a filter he may have been referencing the cabin filter.

 

Yup, that's what I was referring to. ie: if it ain't there, replace it. :)

 

If you want to get to the evaporator the only way to get to with out removing the hvac box is to remove the blower motor and work through the blower motor hole. There is a tsb about mildew and a sealer that can be sprayed into the heater box. I would think you would want your dealer to do that. Here is the tsb number 99-01-39-004c

You can see the tsb using the search box type in tsb and look at post #80

 

Not sure if what I have always done is the best preventative but I have never had a fowl oder from the AC in any car I have owned. That's a lot of car/trucks.
I admit in this climate, AC is only used off and on for approx. 4 months of the summer and once in a while in the winter to reduce interior moisturer.

Each time I use AC, I finish up the day with the AC off and air dry the humidity and moisture out of the system.

Works for me and it only takes a minute with the fan on high.
