I still see some white residue. Dissolve a box of baking soda into hot water and pour it all over that area. The baking soda will neutralize the acid. Leave it alone for maybe 10-15 minutes so it can work, then risnsnoff with hose water to get rid of the baking soda residue that would remain when it dried.
Took it to the dealer for the AC issue and we are struggling. The codes show it was a pressure switch problem. Replacement of that part, and subsequently, the relay providing voltage to that part, and still the intermittent voltage persists. The dealer wants to put it up on a rack and trace the wire coming into the relay. Any input here would be great. Thanks!
