Where is the ED located at on a 07 2.2L?

Its on the firewall, towards the passenger side, really only reachable from underneath. Here are a couple of pics illustrating the drain tube and its location, hope these help.

I just cleared my ED from the top on an 09. You can reach around the drivers side of the air cleaner housing with an air hose and blow into the tube. The water runs out after a very short blast. Of course, the interior smells bad afterward for a while!

I used an empty "zoom spout" oil bottle with 50/50 water and bleach to spray up and inside a few squirts. After bleach smell went away (about two days) then all fresh and drains good for past 3 years.

It was probably mentioned earlier that there is a product made for just this situation. You spay it into the vent and let the foam do its thing. I have seen it in every big box auto parts store.

Frost King A/C Foaming Cleaner is one, GM carries their own brand in the parts dept.
