2008 Workhorse no HVAC Power in dash
Good afternoon,
I have a 2008 Fleetwood Pace Arrow.
MY customer has a complaint of Dash HVAC has no power to it, Power gear Jacks wont Power on (I have Power to the Main control Box, Just not at the control on the dash)
Cruise control is Not working
And the overhead info unit wont Power on either.
I have checked and Tested every Fuse and Relay In The Coach.
Have I missed something, Inspected and cleaned all Grounds?
Thank you in advance.
Uncle Buck

Have you located the coach manual and wiring diagrams for the coach and chassis?
Quite often manual reset circuit breakers are used within the coach wiring - and some are very well hidden (one of mine is accessed through the driver side wheel well on the backside of the firewall).
A wiring diagram can be your friend in locating the the cause of an open circuit.
Oh, and don’t forget to have the “Use/Store” switch in the “Use” position, and that your coach/house (not chassis) batteries are good.

MAYBE one of the schematics that can be found HERE: Workhorse Technical Info will be helpful.
Make sure you select the specific one for the model and year of the chassis you are working on.
Good luck.

Did you ever find the problem? Most of the problems you are having will be coach, not chassis, related. The cruise could be a mixture but most likely chassis only. It sounds like the cruise is a totally seperate promblem unrelated to the others.

Glad I could help. I was half crazy trying to find that fuse for about two weeks of searching.
