The heater blower works but only sometimes. It will come on

Customer Question

The heater blower works but only sometimes. It will come on after hitting bumps in the road. I am sitting in the garage and it just came on. That is half a minute after I turned it up

Hello I will help you with your question,

You either have burnt connection to the blower or the blower brushes are failing.

Do you have a voltmeter to check the circuit if I guide you?

Customer: replied 9 months ago.
No voltmeter handy. I forgot to mention the other problem with that fan or that system. Whenever you turn on the back fan it blows the fuse. I am Not sure if that helps you diagnose
Expert:  George H. replied 9 months ago.

They are on two different fuses so it sounds like you have a couple of things going on. Is it the #34 10 amp red fuse that blows when you turn on the rear blower or the #50 15 amp?

Can you get a voltmeter to check the power to the front blower when it is not working?

Customer: replied 9 months ago.
It's the number 34. 10 amp. I will not be able to acquire a voltmeter tonight
Expert:  George H. replied 9 months ago.

That is fine then, the rear blower control is what the #34 runs to so maybe you have an issue there.

When you get a voltmeter post to this thread and I will be notified. I am here most of the time so we can check the circuit then.
