At the central junction box (CJB), check 20A FUSE 36 for 12V output to the parking lamp trailer tow relay. When the multifunction switch is set to PARK position, 12 volts is applied to the coil of the tow relay, closing the contacts and applying 12 volts to the BRN/WHT wire.

I blew #5 and #6 fuse under my hood. now my running lights stay on plus my overdrive light blinks and my transmission runs bad.


BJB ( aka Battery Junction Box , engine compartment fuse panel ) fuse #5 is for the trailer tow reversing lamp relay & the trailer tow running lamp relay. This is to the normally open contacts on those relays, which is the circuit to the 7 pin trailer tow adapter.
- Have you checked your 7 pin trailer tow adapter for metal left in there from a trailer plug ?
If you pull those 2 relays and replace fuse #5, does the fuse blow ? If so under what conditions ( i.e. when the headlamps are turned on, or when the truck is placed in reverse ) ?

BJB Fuse # 6 feeds the park lamp relay & the headlamp relay for the autolamp function. This could be where the lights staying on it coming from, but I would have guessed just the autolamp would have stopped working.
When the parking lamps are staying on, is this with the main headlamp switch in the auto position, or with the switch turned off.

The blinking OD light is the transmission reporting an error ( trans sensor issue or the actuator circuits have failed ).

The 1st place to check for this ( which is somewhat connected to the BJB Fuse #5 ) is the DTR ( Digital Transmission Range ) Sensor on the side of the transmission.

Could be the DTR connector is gummed up with road dirt, causing an issue. Part of the DTR is for starting ( Neutral or Park acts as a switch ) and part is the reverse ( again acting like a normal switch ) the other parts of the DTR feed information to the PCM for shift control and for 44 ( if the truck is a 4x4 ) for shift operation.

Start with the DTR on the side of the trans, unplug the connector and clean it with contact cleaner, and the check on the relays above.

Please report back your findings as a comment on this problem.

Thanks

The fuses for the trailer tow adapter are in the normal fuse panels.

Engine Compartment fuse panel
101 - Is the battery charge circuit ( hot in run position )
20 - Left Stop / Turn fuse
19 - Right Stop / Turn
5 - Trailer tow reversing lamps & Trailer Tow parking lamps

Cab Fuse Panel
23 - fuse for the relay for the trailer tow battery charge circuit

All of these are in the owners manual

If you did not get an owners manual with your truck ( purchased used ), you can download one from Ford :

2001 F150 supercrew w/ factory towing - No tail lights on trailer


Not sure which fuse you checked.
The Engine Compartment Fuse Panel ( Battery Junction Box / BJB ) is where the fuse is for the trailer tow adapter parking lamps.
Fuse # 5 is the fuse for the parking lamps, and the reversing lamps.

Next is the trailer tow adapter park lamp relay. This is what BJB Fuse #5 feeds, and the coil is operated by the truck's parking lamps. This is also in the BJB, Relay 201, it is the 1/2 size relay.

Not sure what you took a resistance reading from on the trailer tow adapter.

If you want, you can pull the trailer tow park lamp relay, and jumper the normally open contacts, which should provide power at the trailer tow adapters, regardless of the truck's lights.

I have a 2008 Ford F 150 with factory installed trailer wiring. I bought a trailer plug tester. It shows the tail light function to be dead. Brake lights, turn signals all work. Any ideas?


The trailer tow adapter parking lamps is fuse #10 in the cab fuse panel. There is also a trailer tow parking lamp relay that powers them, which could have a problem as well.
Start with the fuse, and maybe check both the 7 pin and the 4 pin for the parking lamps, could be a corroded pin on one of them causing the tester to not see the power on the pin.

Fog lamps dont work i check fuses and relay the switch shows the fog lamps are on


If you have not replaced the headlamp with HID, the next thing, are the high beams on ?

If you turn the high beams on, the indicator lamp on the main headlamp switch should go out.

Next thing would be to check the fog lamp relay in the fuse panel ( passenger side kick panel by the fuel inertia switch ).

The fog lamp relay is a half size ISO relay, you should be able to swap with the trailer tow parking lamp relay ( R201 ), to test with.

The fuse you checked is the F17, the fog lamp fuse for Relay R202, correct ?

F150 Ford 1998 is there a fuse for a trailer and where is it located? Thank you


There are a few fuses for the trailer tow adapter.

1st, is theodd location on the 97-98, engine mini fuse panel has a 20 A fuse forthe stop / turn lamps. Have seen it covered in tape from the factory onsome 97-98 MY trucks.
This is on page 142 in the owners 1997 manual, all the revisions for the 1998 owners manual I have seen do not include this fuse box for some reason.

Download a PDF version from Ford, for the 1997 MY at :

https://www.fleet.ford.com/maintenance/owners_manuals/default.asp

This is a picture of the Power Distribution Box, additional relay box and engine mini fuse panel with the covers off. The 20A in the upper right panel with the red base, is the trailer stop/turn fuse.

The others :
1. Power Distribution Panel / engine compartment fuse panel
Fuse #1 - Trailer tow back-up and tail lamps
Fuse #16 - Trailer tow battery charge and stop/turn lamps
Fuse #28 - Trailer tow electronic brake

2. Instrument Panel Fuses ( cab fuse panel by hood release )
#23 - trailer tow battery charge relay
