Set out to change the cabin filter and that snow balled into taking the blower motor out to clean, clean whatever I could and run some frigi fresh through the system to kill bacteria/odor. Should've taken 15 to 20 min but wow.. The dust in the blower fan was almost baked on, had to soak it in apc and use a ton of qtips to scrub each fin. Where the filter sits there was dust and small particles and a layer of dust on the evaporator. Used a small nylon brush to loosen all the dust and particles off the evaporator and then vacuumed everything up. Wiped off the inner panels with a rag and isopropyl alcohol. Sprayed a little frigi fresh on the evaporator and then followed directions on the can to run through the rest of the air conditioning system. New filter put in and 4 hours later I was done...sigh.. air smells good though..
