What are some of the 2004 dodge ram heater control problems?

The 2004 Dodge Ram's heater blower may stop working or work intermittently due to a failed ignition switch. Owners complain of not being able to get warm air to blow from the Ram's vents after verifying the blower motor's 12 volt fuse, fan and resistor were functioning. Drivers noticed the fan's power could be affected by wriggling a key in the on position. Electrical currents running through the ignition to the blower motor were found to be impaired. In most instances replacing the switch enabled the fan's function. Alternatively, a blower's malfunction is almost always associated with a blown fuse, bad grounding or failed resistors. The average cost to replace the ignition switch ranges from $213-$260 in parts and labor.
