Driver power seat has no power

Mr Sunshine · 08-09-2022, 06:57 PM

My turn for a little forum magic.

Our Hurricane has a power driver seat that isnt working. All the wires and connectors below the seat seem solid. The schematic doesn't show as it wasn't standard. I think there is no power to the seat. The wires disappear into the floor, and don't enter the storage bay below.

I pulled out the chassis manual and there doesn't seem to be a fuse there for a power seat. Anyone know where the power wire goes?

Hurricane? I then suppose you have a BCC under the hood, that is where our seat power fuse is located. Which is actually a auto-reset circuit breaker (10 amp).

My seat gets 12 volt power for the Thor install fuse and relay circuit board up by the driver's left foot. This circuit board is powered by the 100 amp CB on the frame rail, up front by the chassis battery.

Curious now, do you have a BCC under the hood then?

I don’t think the 2016 has the BCC.

I will put that in my data banks...
"2016+ Hurricane - NO BCC..."

I just hope it stays there!
Thanks

I have the full BIRD system in the back of the house battery compartment up high on the front side. There is the typical chassis battery splitter on the positive positive (4 awg to the starter relay, 6 awg to the BIRD, 6 awg to the 100 amp CB and on to the fuse/relay circuit board under the drivers left foot). There was considerable corrosion at the chassis battery even with the red/green felt washers. When I changed to a VRLA battery the post stay clean. I was surprised the original Motorcraft lasted 3 years driving in the east coast rain.
By the way Thor MC shows the specifications as 2016.5 Hurricane 31S-2. what ever than means.

Thanks all. Not resolved yet. There is a BCC, (aka fuse box) under the hood. However none of the fuses are designated for the seat. I didn't see a 10 amp breaker there, but will look again tomorrow. The schematic for the box under the steering wheel doesn't show a power seat fuse either. I attached a pic of the 2nd fuse box under the dash. Is that black 10 Amp in the top left the one Jim meant?

Everything else seems to be working properly.

What model (on front cover) of BCC may I ask?
I am the one that mentioned the 10A CB. That is what ours has.

Different coach but my seats are powered by a 30-amp resettable breaker in the compartment below the driver's seat. (Small thin German one that isn't available in parts stores?

So quite a bit different method of installing the power

That's not a BCC, just a Thor provided fuse box.

The power seat may not even be OEM. Best thing to do is get a wire tracer and trace the positive wire back to the source of its power:

The cover says Ford and has a tiny part # 5C24-14A003-AA. Its about 4 inches square.

Tracing that red wire might be the answer. Can't get to that for awhile. Fortunately the seat is stuck in a reasonable setting.

have you contacted thor and downloaded all the available diagrams for your rig? their customer support line should be of assistance too.

Mr Sunshine · 08-17-2022, 10:30 PM

Yes, I have all the schematics from Thor,. Still a good suggestion. Since the power seat was likely an after market option installed at the factory, there is no dedicated fuse for it.

Here's the resolution. Had to have a little help as I don't work well underneath or upside down like I used. He found that the red hot wire had come loose from a splice in a place where I couldn't see. Sooo, my problem is fixed but I still have no idea where that red wire goes.

Thanks to you all for your suggestions.
