What happens when a blower motor relay wears out?

Without it, the AC system will not be able to circulate any heated or cooled air. The blower motor relay controls the current used to power the blower motor, and is subject to the constant on and off switching. Over time, it can eventually wear out.

Is the a / C blower motor still original?

It just doesn’t cut it in the Georgia summer heat! – the blower motor turns just fine and doesn’t seem to have a lot of resistance to it, although the plastic fan portion itself is still labeled 2/99 so it is original. I’m not sure if the motor itself is original.

Why is the air coming out of my blower so cold?

The air that does come out is Ice cold. So far we checked the selector switch (swapped from properly working truck), inspected the vacuum lines-all seem ok, swapped out blower motor (from the same other properly working truck).

Why is my blower on my Ford Ranger not working?

This is a fairly common issue amongst Rangers, Explorers, and most likely the Mazda B series trucks as well. The main symptom of a failing blower motor resistor is that your fan speed will only work on the high setting.

Why does my blower fan not come on?

Sounds like the blower resistor, or a bad connection at the resistor. You could try ‘wiggling’ the wires on the resistor and see if it comes on. Yep,the resistor is most likely your problem. I’ve been through that mess too!

Why is my blower motor resistor not working?

The main symptom of a failing blower motor resistor is that your fan speed will only work on the high setting. If your fan doesn’t work at all, then there is most likely a blown fuse, issue with the blower motor, hvac panel problem, or a fault in the wiring.

What causes a bad or failing blower motor relay?

Blown fuses. One of the first symptoms of a bad or failing AC blower motor relay is a blown AC blower motor relay circuit fuse.
