Take a look at my evaporator, this view is with the blower motor pulled out of the way and the boot off. As you can see, there is a slight bit of blockage.

Duh........might be why it's not as cold as it should be.

This stuff is like hardened dryer lint. Tried to blow it out from inside the car, no go. Slowly working it off with a vacuum and a narrow attachment. It's a slow process.

You can also see the resistor pack in there. That causes magic blower syndrome.

No man, that's a micro particulate filter. The thicker the coating, the better the filtration. Kinda like a K&N.

Sean,
I have some blockage like that, but just not as much. I was thinking of maybe trying some of this:

I have used this stuff at home and it does wonders on loosening up the crud. The can is designed so that it will spray even if it is upside down. The foam is supposed to be self cleaning. Do you see any drawbacks on using this?

GregBBRD

That's amazing. Is there dust in Texas?

Is that an animal cracker I seen in there?

SeanR

Ahh, this is much better.

There's not a lot of room to get a hand in there, or any sort of tool to clean it. Tried to be gentle so I wouldn't bend the vanes, but hell, this has to flow better than what was going on before.

WallyP

I would use the foam now.

SeanR

I think I'll go pick up a can of that stuff. Thank guys.

That was nasty. I think I'll have to take a peek at mine.

Do you think a vacuum with a brush attachment would work? Just thinking of the bending over the fender and reaching in hurts my back.

How long since the last time you cleaned it Sean?

As long as its just caked on dirt and greese, the foam will clean it up. It will rince itself off on evaporator coils. I used it on the oil cooler, condenser, and radiator then washed them out with the hose. It's cheap and it works!

I just did mine with a notiecable improvement of colder air as well as a "fresh air" smell. Mine was no where near as bad as that.

Be careful using a vacuum cleaner attachment at the evap fins are really soft. Easy to mangle, similar to the shiny "dents" in Sean's.

I tapes a 1/2" rubber hose to my vaccuum. Seemed to work well.

A combination of vacuum, compressed air, simple green, and a brass brush yeilded good results. Rinse and repeat.

Make sure your drains are not clogged and water is flowing out the bottom of your 928. Otherwise the condensate is building up and flowing down your interior bulkhead (past heater core) and saturating the foam insulation on bulkhead.

I used the foam on the Stepson. There was so much crap that it plugged up my drain hose. I then had to clean that out. It would probably be a good idea to use a garden hose and wet/dry vac to get as much foam/crap out before sealing it back up.

End result is really worth it. Especially the last 3 weeks here in Texas.

SeanR

Do have but didn't use

Never


I'll find out as soon as I finish lunch.

John, good advice on the drain. I don't have any issues thus far, but that might change after spraying this stuff on.

byrdman454

What is the easiest way to unplug the drain if this happens?
