Interesting. So I have sort of the opposite problem. I never see regular condensation under the car. Used Klima cleaner and Nucalgon recently. I removed the cabin filter and fished the small hose that comes with the Klima cleaner toward the condenser (the middle of the car).

Did not remove the blower motor because its on the opposite side, and the foam shouldn't really back up to the blower. (you can stuff some paper towels in the cabin filter area) Did you spray the foam toward the condenser? I got a lot of cleaner flowing out of the drains and its was actually brown with the Nucalgon so must have cleaned something. Its been too soon to see if smell is gone because the Nucalgon has a strong lemon scent.
