A while back I remember reading a posting that indicated a bad ignition switch could cause some problems with the blower. I fidgeted with my key as suggested and the blower did work. My question is what part do I need to buy to fix this problem? Is it the ignition switch, the ignition wiring, or the ignition control? Is it a hard fix?

thanks,

John
