My SR5 this winter has been kind to me and decided that its heater core will stop working. Especially with such record-breaking lows this winter. My Sedan's heater core works but the fan is clogged. I desperately need to either un-clog the fan of my sedan, or transplant the heater core to my SR5. Can anyone provide some write ups for how to do this? The quicker the better, I can't feel my toes!
