I have revived a few old clunkers and the cleaning of the blower and ac evaporator coil has become almost standard. The amount of debris clogging the ac coil is kinda tied to how much the car was exposed to leaves and trash that accumulates under the wiper arms. BUT, sometimes one gets help from little critters just looking for a new home. This is of the worst i have found.
