AC Ducting

[NavyChief200]

Trying to replace the Data wire that goes from the front AC to the rear. 36' 2006 Holiday Rambler, Neptune. Removing the ceiling is not an option. Tried to run a wire snake down the passenger side AC duct, but ran into a 90 degree turn at the bathroom. All batteries are removed for the winter, so running the slides out to get to the driver side vents would be a little bit of a pain. Any ideas.

If it's close to one of the vents maybe you could throw a fishing weight (with a string tied to it) through the vent to the nest one. Long shot I know but depending on the vent it might be doable.

Do you have access to 120v power or compressed air? Maybe tie string to small wad of paper and try to blow it down the duct?

[LCharron]

Couldn't you just tie the new wire to the old one, if you have access to it, and pull the new one through?

[NavyChief200]

The old one is stapled to the supports. I'm using a wire snake.

Any possibility of just running the wire on the floor until you can get the slides out? Not sure if that would help short term.

Any speakers or lights in the ceiling. I've broken out a bit of the thin veneer behind the fluorescents (now led) lights to allow access

On mine the ducting is down the center with low voltage on the passenger side chase and 120v on the driver's side of the duct
