2000 tj came stock with no rear def. broke glass recently and decided to get one with rear def. I have a 3 prong rocker switch drawing power from the fuse box behind glove box and a ground next to it, the other prong obviously I ran a wire and split it to each of the def. tabs. you can see in pic I have 14V running to defrost lines. but it wont defog or burn off ice. any ideas?
