heater motor or switch, how can i tell what is bad?

[quote:3611daf753="rod4jesus"]i have a 2005 Suzuki forenza and after hitting more than a few bumps the heater motor stopped working, however a slap on the dash would restart it. But not any more. what must I do?[/quote:3611daf753]


Its time to replace the blower motor
When you used to hit the dash you shaken the brushes and that make the connection for you and now it’s not happening
