My heat is not working and i already change the blower motor what elas could it be

Hello, for what reason did you change the blower motor? Was it a guess or did you verify it had failed? The problem is if you guessed, you may not have ever addressed the problem. Testing will be required in the related circuit to see what is happening to all the various components. No one can offer any guesses that have any validity - only hands on testing can help.
