Test The Plug On The Blower Motor For Voltage If It Has Voltage Test The Blower Motor If Its OK. Most Likely Your Plug Is Bad Loose Or Broken Wire If So Replace It. Good Luck Remove The Wire Pluged Into The Blower Motor, Test To See If You Are Getting Voltage. Also Check The Plug On The End Of The Wire You Removed. You Will Most Times Find A Bad Connection. Like A Wire Loose Or The Rubber Deterated. Buy This Plug If That Is What You Find. Get Some BUTT Connectors Install The New One. Be Sure To To Correctly Get The Colors Right. This Should Take Of It.
