My car has coolant in it, the car runs fine, sometimes the air conditioner works and sometimes it doesn’t. I’m thinking it’s my blower resistor, but I’m not sure.

If the air stops blowing from inside the car out through the vents, then it is a blower motor going out. But to be sure we can use this guide and I have included the blower motor location and how to change it out in the images below:

This guide will show you how to check the power and ground of the blower motor to help confirm the failure. The blower motor is under the right side of the dash.

This guide may help as well:

Check out the images (below). Let us know what happens and please upload pictures or videos of the problem so we can see what's going on.
