What causes a blower motor to overheat?

Decreased airflow causes the blower motor resistor to overheat and fail. Reduced airflow also causes the blower motor to work harder, draw more current and that can cause repeat blower motor resistor failures. Blower motor is drawing too much power. Check the cabin air filter for clogging.

How can I tell if my blower motor is failing?

On all systems, a failed blower motor is least likely. Blower motors generally don’t fail out of the clear blue. In most cases, they start to fail by making a high pitched squeal or screeching noise that indicates the bearing is failing.

Why is the AC not working on my Dodge Ram 1500?

Another common Dodge Ram 1500 air conditioning problem is that the AC will work, but after some time, it’ll get hotter, and then the temperature will drop, and so on. In many cases, a drop in temperature is related to some restriction inside the system.

Why does my AC blower motor stop working?

What are the resistors on a Dodge Ram 1500?

The resistor values are: 0.5 Ohms between the common pin and H 0.75 Ohms between the common pin and M 1.5 Ohms between the common pan and L They can be a few tenths of an Ohm off. That plus your Ohm meter is probably not that accurate 🙂 My guess is that the 1.5 ohm one is a 40-50 watt resistor. 12 people found this helpful. Where is the relay?
