New to the forum here so try to bear with me...have a '97 Rodeo/Passport and the blower (vent, a/c, heat, etc.) crapped out on me a couple months ago. It started out only working in the #4 position but has since stopped even at that speed. I have been reading over past posts and it seems to be an issue with the resistor, relay or the switch. I had gotten a new motor and tested it by plugging it in and it still did not turn, thus why I'm thinking it's not a problem with the motor. Where exactly do I find these parts and how do I test them? Also, if it turns out one of these components is faulty, where would I look to find a replacement?
