2018 Accord
 

Theres a fan blowing air underneath the driver seat and lots of dust collects there. I am looking for instructions on removing the seats and more where simply vacuums and tools cant reach.

The ventilation system is giving off a foul odor and I tried spraying stuff in the air intake and other vents. So I also wanted instructions to acessing the evaporator safely because I feel like doing some thorough cleaning.

Not sure if it matters but the model is 20T.
