My blower in my car recently stopped working. I was going to first check the relay to see if that was the problem, but I can't seem to locate it. Any help would be great.

Thank you

My heater blows air sometimes and other times it does not. You can't hear anything, and no hot or cold air comes out. Usually in the morning it blows air just fine, but by the time I get off work it stops again. Sometimes pot holes make it work and other times it stops it from working

Some people told me its the blower relay, where is that located and which is it?

Hi:
I believe the relay is located on the passanger side under the hood to the HVAC box on the firewall. It could also be the blower motor resister, or a loose connection.
