Heater mower jus stopped fuse not blown

Tthis car only has 45000 miles on it and this is my first issue. Can anyone give me a direction as to why it won't blow. Changed fuses in number 9 spot on fuse panel. Is there another relay or breaker for heat and air also?? Thanks any help is appreciated

You're not supposed to use the heater for a mower... :hick: What you been smokin' ?? Not been smokin,' mowin'...


Any type of bad connection/open circuit will cause blower to stop working and not blow fuse... When circuit path is interrupted no current flows, fuse is waiting for a short, not open...

IF it has EATC the blower controller is most likely suspect, time and electronics that don't mix well...

Work backwards from the blower.  Find that first connector behind the glovebox coming from the blower and apply battery voltage there to verify the blower will run.  If it does, go to the blower resistor or blower contol on ATC.  Finally, check the connector on the back of the blower speed switch, the high current has been known to melt the connector and cause an intermittent connection.
