Troubleshooting Curt C55530 4 Way That Isn't Getting Power On 2008 Pacifica  

Question:

Expert Reply:

Hey Dennis,

First, how did you verify there's no power at the 10-amp fuse for the Curt # C55530? Did you use a circuit tester or multimeter? I'd also double-check that the factory 2-pin connector near the rear taillight is fully seated and that the 10-amp fuse is actually installed in the inline fuse holder.

If everything is connected properly, I'd check two fuse locations in the underhood fuse box:

Fuse #10 – Trailer Tow: Check whether this location is actually there and has power.

Fuse #11 – Power Liftgate: This may also be associated with the factory power circuit feeding the rear connector.

Let me know what you find out. I'm leaning towards a fuse needing added (even though Curt instructions don't call it out on this year Pacifica).

Hi Andrew I use a multimeter. On a 2008 it does not have a # 10 fuse spot. There is no designated spot for trailer tow. Tomorrow i will check fuse # 11. Why do they call it a 2-pin connector, there is only 1 wire. The proper connector is exactly where shown in pictorial but has no 12 v. Must be fused somewhere. Thankyou for your response. I'll let you know how i do

@DennisH Hey Dennis. I'd check the owner's manual or try looking it up to find where that wire runs to, as it has to be connected to a fuse box or power source of some sort. If you can find where it goes and add a new fuse, you should be good to go. Absolutely worst case scenario you can run your own wire to the fuse box with a fuse-tap or straight to the battery positive terminal with another inline fuse near the battery, but that would be a bit more work for you of course.
