Heat/AC blower motor not working

The heat/AC blower fan has been shutting off intermittently and now does not come on at all on any setting. Is there a relay that controls this fan? Both the heat and A/C function properly, it is just the blower that does not work.

Thanks for this post. I had to get a new blower motor for $76.00, but it is all fixed. I love this site!

Check the gauge fuse 10amp and the heater fuse 40amp if both okay-if heater relay is good-problem is coming from the blower switch or blower motor to include the ground behind right kick panel.
