I started this thread a while back and all this is great info. I too found it's the heated jets issue. The pump is pumping the liquid out fine. I finally went to remove the plastic cowl (for the second time) and I can't get the wiper arms off. Someone on here mentioned using a special tool. Is it the only way to get them off? I do want to get this darn issue fixed and I have some time to do it now but I don't want to have to buy another tool unless absolutely necessary. Anyone have another way?
