Has Anybody added a Vent Fan w/No 12v connection?

Yes, but you do have to get power from somewhere

do alot of looking and plan your route. before you cut drill.

I installed vent fans in kitchen and bedroom using power from nearby ceiling lights.

There's also adhesive-backed flat wiring for surface mounting.

I wired a fan upgrade for our front vent by pushing a coat hanger fish wire through the foam insulation between the ceiling and roof from a nearby light fixture to an A/C duct, and then from the duct to the vent opening. Once the fish wire was pushed through, it was used to pull the wires through of course. The closest light fixture to the vent is wall switch controlled, so I had to get the power from a fixture a bit further away that was direct wired with an internal switch.

Have you actually pulled the trim from around the vent to VERIFY that there is no 12 volt wire there? It would be kind of rare to not have one near by.

I installed a vent fan in our bathroom (there was no fan) and pulled the wire through the roof to a nearby light. Very simple to route the wire this way.

Thank you fine gentlemen again. I will rip the fan housing apart to make sure there is no power there. If not, I will try to fish it through somehow taking care to plan my route to the power source.
