Musty Smell in A/C and cabin; any banana fixes?

I spoke with a BG tech at a local shop and he told me to spray 1/2 the can into the evap box, just open the door and put the tube in there. The stuff foams like heck and fills up the box. When it got close to the opening, I removed it and put the cover back into place. Ran it for 10 minutes without a/c on.

Repeated with the second half of the can and ran for 10 minutes with a/c on full blast. Nothing split and worked like a champ without drilling a hole. He also told me to finish by spraying the evap with water and running a/c again to complete flush. Hope that helps. I am not very skilled and it was very easy. I have to think that the drilled hole is for boxes that do not have an opening for filters.

Thanks for posting this. My LC is one of the ones that does not have an opening for filters. Still need to figure out where I can drill a hole safely.
 
After using this product on both my 80 and 100 series, I think it is a waste of money. After both "treatments" I still had to access the condenser area via the resistor pack in the 80 or the air filter window in the 100 and spray the condensor down liberally with a 1 gallon garden sprayer full of water. In the 100, I also had to make an adapter and use my shop vac to suck the crap out that wouldn't make it's way to the drain on it's own.

You'd be far better ahead to use a heathly dose of 409/lysol/ or soap and water and then spray it down with clean water.

Just my $.02, but I regret wasting the money on something I could have done nearly for free.

The product is not designed to do away with mulch in your evap box, you are required to clear all of that crud out of there.

If you apply the foam without cleaning the evap box, then it is like waxing your car without washing it first, the wax is not going to do its job.

Once all of the crud is gone, the concentrated foam does its magic on the coils. You are paying for the convenience of squirting in a can and walking away for 10 minutes.

I tried the 409 first and it was a lot of work with the end result being marginal at best.
 
My experience using their directions was also marginal at best...

Agreed, the BG stuff won't get rid of major crap, and there wasn't that much, but it was enough to justify getting out the shop vac. Also, on the 100, I pulled the air filter window immediately after adding the foam and only 1/2 of the cavity was full and I didn't even turn up the AC fan at 100% per the directions. At full speed, the blower would have kept the foam from rising higher.

Anyway, to each his own. My recco is to forgo this treatment. I'll use 409 in the future, spray it down liberally, and then use the fan to push it through the coils. Let it soak and then spray down with water. It's a whole lot cheaper and just as effective in my book.

I used the OEM Toyota kit (two aerosol cans, one big can of foam, one small air freshener can: ~$25 at a dealership). For clarification the nipple you're looking for for the front condenser is, on USDM vehicles, on the passenger side to the outbound side of the header. It should puke out foam as such all over your skidplate unless you're smart enough to catch it.

Please be more specific on where to clean out the leaves? The box under the glove box and where else?

Thank you.
 
This is what I found in the evaporator box:

Mine didn't smell bad, but with two new air filters in there (and the new access cover so I can replace the filters periodically) the air is nice and fresh now...
