Re: AC Evaporator location, 97 Tahoe
FWIW, the evaporator can be easily accessed through the blower motor hole. I would highly recommend cleaning the evaporator to anyone that drives in dusty conditions or that has noticed reduced airflow through the vents. I had about a 1/4" layer of mud caked on the evaporator, cleaned right up with a garden hose and some spay-on degreaser. My a/c feels twice as cold and powerful now.
My leak was in the schroeder (sp) valve on the compressor
