wow, you're not the only one. me and another guy on here also, he posted something similar. when i turn my blower on, all of my lights go out, but when i turn it off all of them turn back on. I live in AZ and commute ten minutes to work so no biggy for me, just annoying. but i think the other guy who posted the similar problem said after doing some research that it might be tied to the ignition switch, or maybe it was another member who posted that cant remember. anyone have anything that they can help us with this issue
