ok my rear defrosters now that it is getting cold, they only work sometimes, i can press and press the button and they wont turn on, and then when they finally turn on, im at where ever i was going to. Is it maybe a loose wire, or what, if you guys could help me out, that would be great, and thanks for whoever helped me with the windows, got those working fine, but the auto locks are being an ass. Thanks again!
