Hello,

This sounds like you could have a problem with the electrical connector or an open in the wires going to the blower motor. In the diagrams down below I have included the wiring diagrams for your vehicle's blower motor circuit. I have also included a guide for how to find an open in an automotive electrical circuit. You will need to use a Digital Multi-meter [DMM] to go through these guides, so here is a link below explaining how to use one, if needed:

Please go through these guides and get back to us with what you are able to find out.

Thanks,
Alex
