Gang,

I have a 2004 Coupe. Last summer, I replaced the Blower Motor Resister with a Ultra-Power RU547 ($33.79) from Rock Auto. Installation simple and has worked like a charm. On Saturday, a burning smell come from the dash. Turned off the car and it stopped. I had the car towed to my dealer, who has confirmed that both the Blower Motor and the Resister are "fried". The parts from the dealer are insane ($1500 for the motor and $921 for the resistor). Rock Auto has a few options for the Blower Motor (GPD $120.00, Four Seasons with wheel $139.00, Mopar 5139032AA $298.00 and Mopar 5139032AA $1007 which is what is in the car). Wondering what could have caused the parts to fry? Is it possible for the Resister to cause a short and fry itself and the Blower Motor, or is there something else in the circuit which could have caused the frying of the components?

Thoughts ...
