my button pushes in also, I will have to check that out. I do not have to wait, my cars are in a heated garage along with two lifts. I just finished putting on door panels and back panels. if I get to the wiper washer and switch I will let you know if it works when you push switch in. I have to install steering column next then on to heater box, then the carpet and much more! I hope to have it done buy spring time.
