I am planning on a total cleaning of my AC system this spring when the weather gets warmer. I plan on replacing the cabin air filter again and using a product called BG Frigi cleaner and BG Frigi Refresher to clean so my AC system is totally clean. Instead of going to the dealer and probably spending hundreds for the TSB for it, I plan on doing it myself for around $50. The BG Frigi cleaner requires the access of the drain tube (where the water drains out of the car when using the AC). I was wondering if anyone knows if its accessible without elevating the car and if its easy to locate. I would look but the weather here is cold and lots of snow. Thanks in advance.
