Front Heater blower not working and took to repair shop. Replaced blower motor and resister and still would not work. Repairman indicated that the dealer service said there were some wiring problems so he suggested we take to dealer. Has anyone had this problem?

If there is a wiring problem, then why did the shop replace the motor and the resistor? You should take it to someone proficient in electrical diagnosis.
