When you turn the a/c on does the cooling fan come on? Mine doesn't turn on and I though when you turn the a/c on it turns the high speed fan on. Ive replaced the ccrm thinking it was bad but even after that it still does not come on. I also replaced the fan itself due to it being loud. The low speed will come on after a while but only because the high side is getting to high and then as it lowers the fan will turn off and as it build higher again it comes on. I checked the fuses and all...
