About a week ago, my fan quit working. I could still feel heat, but no forced air. Checked the fuses...all good. Tried different settings (Feet, vent, defrost), but no dice. Occasionally I could hear a slight clicking but not much else. Lowered the temp to 65 and clicked A/C and all it did was flash and go off. Then this morning I stopped for a cup of coffee and left the vehicle running and when I got back in the truck, it was blasting away like it used to. Before I take it in and spend an arm and a leg to diagnose the issue, I thought I would ask you all if you have any advice. I am wondering if I have a short, bad relay or bad connection. Your thoughts?
