Default Evap cleaning?

My blower motor is not that strong. The AC blows cold but not strong enough. I read the directions for cleaning out the evap but have a question. Do you remove the blower motor from the firewall and spray the inside of that area with brake cleaner and then flush it out with water? I don't want to short anything out and want to make sure that is where I need to clean it. Thanks guys.

No, don't remove the blower. Just go through the little opening (2 screws) on the top of the evap core housing, under the relay center.

You know where the relay center is under the hood? Pull the cover off. Just below it, in a box mounted to the firewall is the evap core. Little panel on top held on by 2 screws. That'* where you go in. Spray and rinse through there.

Ok, we won't tell any short bus jokes, but you have to help the next guy. Open your hood and stand between the headlights (on the street, not on the front bumper). Look almost dead center at the firewall. See the back end of your fan? Look to the left. Inside that black cover. Pull the cover off the relay center above it. Right under the rear hood gasket. Big long black plastic cover labelled '"maxifuse/relay center".

Now remove the relay panel. 3 ten mm bolts I think? Someone help here. It'* been awhile. Lift it out of the way as far as the harness will let you. Now you'll see a little square gizmo cover with 2 screws. It'* about 3 by 4 inches? On top of the evap core housing on the firewall. Remove it. Look in there with a flashlight.

Ok, let'* step back a minute and rehash this. What are your symptoms? Just low flow, or not coming out the right vents? Not getting cold?
