I first watched your video on how to replace the evaporated drip pan which was rusted through and whose rust clogged the drain tube. The directions were clear. I did have to blow out the drain tube before installing the new pan. I also replaced the evaporator assembly because I felt the old fan was not working properly. Your directions were also valuable with that repair. Although it took four months to get the fan assembly because it was on backorder, the job went well. Thank you.
