Im so sorry to offend about reducing the vehicle. Im 22 its my first vehicle. I had free work done on it before I bought it. We bought it through someone who got it and fixed it up for free. It needed a bunch of repairs and they just ripped stuff out that weren’t working to save costs. I got it October of 2021 for 13k. Only 63k miles on it when I got it. I believe I read somewhere that there is a relay somewhere where you had to take the ac vent. I dont remember what side it was on thoughI'm going to move quickly past the reducing of a luxury vehicle to a normal vehicle And on to , could the wipers be draining due to trying to talk to them with no response? As far as I remember reading elsewhere the relay may be built into the wiper assembly, or under the dash, depending on year. Although one of the more technical types may be able to answer that one.
