Thread: 2010 F-150 Trailer Plug not working. Can any Ford mechanics help me?

Tweet

The plug work fine until I put my boat trailer into the water. I unplugged it and then when out of the water plugged it in again. Went to hook it up to the car trailer and all I have is the running lights. No blinkers or brake light. The truck blinkers and brake light work fine. Which Fuse is it?

Under the hood, there is a box - LH side. Should be 20 amp. But since my last F150 was an '01, Ford may have changed it, but my '06 F350 fuse box is still there.

When you back the boat in/pull it out, disconnect the pigtail. I learned that lesson years ago

I don't have anything on a 2010 yet,but IC2 is correct there will be a fuse in the under hood box for the trailer system. Your owners manual will show the grid.

I too have a 2010 F150 Supercrew pickup. There are two fuse panels on the F150. One is in the engine compartment that is centered right in front by the radiator. The other is in the passenger side kick panel.
I think the fuse is in the kick panel location but the owners manual will tell you exactly where and which fuse(s) would be in question. It could also be a relay so you may need to swap them out also as appropriate. I would tell you the exact location and fuse/relay, but I'm at work and won't be able to check it out until much later.

Tom, where the heck did you steal a truck that new????? Whatever happened to the old one, if it finally died hope you took it out back and give it a good Christian burial!!!!!!

Here is a bit more information that might help. This is the battery box fuse/relay center that is under the hood (front over the radiator). This will show you the trailer relays in question...

I have a 2010 Ford F150. What fuse/fuses need to be added to - JustAnswer

Jerome,
I'm using the 4 pin connector so the referance (95-3) wont help me.
I went to my Ford dealer today for free help. Fuse # F6 a 20A (Turn singles, Stop lamps)($4.65) was OK in the passenger kick pannel. Under the hood #31 a 20A (Trailer tow park lamp relay) was OK. Next step was to check the Relays but mechanic was called off to do a paying job but gave me a copy of 95-1 (Trailer/Camper Adapter). Looks like (Trailer Tow Relay, Left Turn and Trailer Tow Relay, Right Turn) which I found from the stuff sent will need to be tested.
Question... How are they tested?

Dave,
It didn't Die, I just couldn't drive it due to my sore left knee. After 30 miles my knee got REALLY sore. I have to keep my leg stretched out and there's no room to do it in the 94. I also had a 92 4x4 which had the same problem. I traded both of them and my Short Box regular cab 2010 (big blind spot behind passenger seat) in on the extended cab. I went in to buy a 2011 but they didn't have what I wanted and it was going to take two months to order it out. I spotted the 2010 Extended cab in the lot which was the last 2010 they had, and asked about it. they said it was a 4x4, told them I didn't need 4 wheel drive. Just then the owner stopped in and inquired about what I wanted and said "How about if we knock off $12,000.00 right off the top..... then would you be interested?" I bought it. If I knew how to post pictures I'd post them. Oh ya of course it's Black.

Picture posting is pretty much the same, Tom. Hit the "go advanced", then "manage attachments", then "add files", then "basic uploader" and this will take you to the Browse function where you put up the pics from your own computer..... Just one more step then the old system. Couldn't be too difficult, heck I can make it work!!!!!!!!!!

Hi Tom,
Not sure if you fixed your problem or not. Was not online for a while due to the holiday. Best way to test a relay is.... well.... swap it out with a known good one. If it works, then you have it. That multi function relay sounds like the bugger as it handles everything out to the trailer jack.
