Hey guys, hope all is well. When I turn on the blower to defrost my windows it doesn't work. I checked the fuse and it was toast so I replaced it. Then it still didn't work. SO I switched the starter and blower relays and then it started to work again for a while. Now it did the same thing and stopped working but I find it will randomly turn on and off by itself when I am driving but never works when I want it to. What do I do here?
