I first noticed the issue when the setting for the blower stopped working on its highest setting. Over time the other settings started malfunctioning. Now it barely works and sometimes a "friendly" bump is needed to get it moving. Could this be solely a switch issue or am i looking at motor replacement? Winter is coming!! Any advice is greatly appreciated! Thx

 

 

Sounding like motor to me. You could gamble on a new switch or test it. Just remember it is not wired the way you think it is; the switch goes to ground the bat+ goes directly to the motor.
