It will function fine for long periods of time and and then stop. Starts again the same way. It worked for over a month without issue. Stopped for a couple weeks and then started again. No warning in either direction.

One day It will start it up and the heater kicks right on no problems, and then another day I start it up and it will no?

Do you have a multi-meter to do some testing?

I have a test light and have tested all the fuses and they are working fine. However, I do not have a multi-meter.

What you need to do is test for power and ground at the motor when it is not working. Also, have you checked for a loose or open terminal at the blower motor connector?

I had this problem with mine. Turns out it was intermittent loss of connection at the blower resistor. When it would stop I could touch the resistor, which is on the bottom of the heater box and it would start working. Until it did not. I bought a new resistor that included a new connector and pigtail and it solved the problem. Hope this helps
