Sometimes the blower comes on and sometimes it doesn't. Can it be the blower motor switch, relay in the fuse block, blower motor resistor or the blower motor itself? Also, i need the location of the blower motor resistor.

Hi,

I attached the resistor information you requested. However, I would start with replacing the relay. Intermittent operation is normally the relay because when it gets hot it stops working.

To answer your question, it could be any of the things you mentioned but again, I would start with the relay.
