I spent last winter without a heater. For some reason my fan quit. Nothing I did would make it work. So, I finally broke down and bought a repair manual for my truck. I went out, checked all the fuses, all the relays, eevrything I could think of--and it still didn't work. In disgust, I hit the fan motor with my pliers. It works now.
Continuing with my new found streak of mechanical know-how, my oldest daughter J called us from Green River last night. Her car had broken down. When we arrived, we found a large hole in her radiator hose. All of the part stores in town were closed, so using all of my mechanical abilities, I got out my roll of duct tape, and wrapped about five layers around the hole. It held until she got home where we could replace the broken hose.
Maybe I'll open a shop...maybe not.
Take care. Stick.
