Heater problem found (I hope!)
I have been having problems every since the blazer heater motor upgrade. It would work for a while then would pop the fuse. Yesterday I was going to by-pass the wiring and run a hot wire and a toggle switch so I would have some heat. We hooked a wire from the battery to the motor to test it and it fried the wire. Hmmmm. My friend said the motor must be bad. NO, I screamed, I just replaced it! Thought the first one was bad so I put another one in. PITA. We got to looking and the "spade" on the motor was touching the firewall, direct short! A little grinding, some sillycone and Ta-Daa, it worked great! Seems it would bounce around and make contact with the firewall and pop the fuse. I wheeled in a t-shirt in 4" of snow (what a blast we had!) and 20 degree weather today. For the first time in a long time my jeepchick was warm in that "cold-ass" jeep of mine! All in all, a great day! If I had a butt kicking machine I would be wearing it out on myself for not finding this sooner...
