Have Ford Questions? Ask a Mechanic for Answers ASAP
Hello and welcome. My name is ***** ***** you for visiting the site, I am reviewing your question and will reply shortly, thanks.
When it is not working, do you know if there is power to the blower motor?
I see, thanks and is there also a ground connection at the other terminal?
All electronic on the auto temp. Is it that the blower does not come on?
Yes, that could be in the blower motor or the blower motor controller and the only way to know is to do the test, thanks
That is electrical. We can discuss it for as long as time allows and still never know until the test is done, thanks
The blower motor is controlled by the blower motor controller through the ground circuit. Please see attached diagram, thanks
Which is why I asked if there was a ground at the other wire.
I didn't make them that way, sorry.
That is just how the circuit is designed and you can either change a part or test the circuit.
Hi, welcome to Just Answer. I'm Ron and I will be helping you today.
Jerry was spot on with the ground circuit being a possibility, but you can easily test the motor with an ammeter to see how much amperage draw it has when it's acting up.
For obvious reasons, the amperage draw will be fine if it's working fine.
From My experiences though, you have a flat spot on the armature of the fan motor and a new motor will fix it.
Hi, I'm just following up with you to see if you have any more questions.Thanks, Ron
