E450 dash wiring

Hi all,

My Coachmen Freelander 32BH, with a Ford E450 chassis front end, has some issues I'm having trouble sorting out.

Symptoms are that the windshield wipers, wiper fluid pump, A/C compressor, A/C fan, and running lights all seem to get now power.

The gauges all light up and the radio works just fine. The engine turns over just fine and it drives as I would expect.

Has anyone come across anything like this before?

    Some good information to note. Sounds as if it is common problem. Thank you Mr.HomeSweetRoam.

    Update to help people looking for the same issue:

    I fixed this by investigating connections and wire harnesses BELOW the dash near the gas and brake pedals. This turned out to be loose connections to the GEM (Generic Electronics Module), which looks like a 2nd fuse box. Re-seating all cables to it did the trick!

    I actually got tipped off to this by an Ambulance mechanic in the area who works on rescue vehicles with Ford E series front ends. From now on I will include Ambulance mechanic shops in my resource list for wherever I am travelling!

    Has anything been repaired, replaced, modified, recently? Do you have additional accessories like a Brake Controller?

    Under the hood of the E-450 in left front is a
    FORD power distribution box.

    It has the large fuses for major systems.

    I would start there.
