The issue with the heater blower in the 2004 Dodge Ram could be caused by a faulty ignition switch, leading to the blower not working properly or only working on and off. Ram owners have reported difficulties in getting warm air to come out of the vents even after confirming that the blower motor's fuse, fan, and resistor were all operational. They have observed that jiggling the key while in the on position can impact the power to the fan. Problems with the electrical connection between the ignition and the blower motor have been identified as the cause of the issue. Replacing the ignition switch often solves the problem with the blower fan. On the other hand, if the blower is malfunctioning, it is usually because of a blown fuse, poor grounding, or failed resistors. The average cost to replace the ignition switch, including parts and labor, ranges from $213 to $260.
