Engine Bay Exhaust Blower Fan Switch??

[Joe Lee]

Hi All - I have an exhaust fan in the engine bay of my 1996 Crown Royale Signature. I replaced the fan but the wire going to the fan doesn’t seem to have power. Does anyone know if there is a power switch for this fan?  I expected the wire to be energized when I started the coach, but no luck yet. 
 

Any help or ideas are appreciated!

May be controlled by a thermo switch, when the engine bay gets hot it turns on.  You might try bringing it up to temperature.

Great idea!  I will do as you recommend. Thanks!

As mentioned it is controlled by a temperature control, it looks like a high limit switch used in furnaces. The temp setting can be changed by rotating the setting.

Its under your bed.
