Ford F-150 - 1997-2003 :: 1998 - Brake Lights Not Working / Clicking Under The Dash
Oct 14, 2014
Brake lights do not work. The turn signals work, the flashers work, and the running lights (head lights) work. I checked the bulbs and both filaments light up during the above processes.
I removed the brake switch at the pedal. When I was removing it, I heard some clicking under the dash. I connected the 2 pins with a wire (bypassing the switch), and got a spark a few times along with the clicking sound like a relay,and the brake lights would come on, but now nothing. No sparks, no clicking. The flashers and turn signals and running lights still work.
There are no blown fuses in the fuse box to the left of the steering column. Is there a relay somewhere under the dash just for the brake lights?

I have a 98 f150 4x4, 4.6L 150k miles, during start up the blinker indicator lights on the dash illuminated and stayed on, when trying the blinkers they did not work, but if I shut the head lights off the blinkers do work and indicators respond normally. This is the same if I turn the fan blower on, blinkers don't work and indicators stay illuminated. Also I have found that the power windows, and 4wd no longer work. Other functions work such as power mirror, radio etc. all fuses under the dash and under the hood are good, I tried switching some of the relays to see if that changed anything but with no success . took the kick panel off and inspected the grounds and all seem tight. It looks like the main battery ground is just to the body and there is one solid ground from the frame to the body under the cab. all seem tight and don't appear to be corroded. Truck starts and runs great.

I am working on this 97 F150 with the EOTF. It is not doing anything. When i turn the key on, no light on the dash comes on. When i operated the 4wd switch, nothing happens, no lights on the dash, no relay clicks or transfer case noise, etc. It has a new t case motor, the switch tests out good. I have researched for a while, and either find people with different symptoms or the original poster never updated with what the fix was. I am unsure where to go at this point, i am suspect of the GEM or the t case relay, but don't want to go replacing stuff without a basis for going so. Ive tested for voltage at the switch as well and it has 5 volts at pin 3.

I noticed that my break lights are not working. Checked the fuses . The break light on the cab works fine. The blinkers and emergency flasher work great. i checked the bulbs and nothing wrong there. Truck runs and drives great. But no break lights.

I have a 1997 Ford F250. My trailer lights will work, but I have no brake lights or turn lights. I have checked all my fuses and all the fuses are good.
I was told it was probably my trailer tow relay, so I bought it at O'Reilly's, but I don't know which relay it is exactly.
I just want to know which relay number it is so I can replace it. And, if this doesn't sound right, is there something else I should be trying?

I have a '97 F150 and the trailer break lights and turn lights are not working. I have checked the fuses under the dash and hood and all fuses look fine. I have also tested the trailer on another vehicle and checked the wires. Trailer lights worked and wires and connections looked fine. In searching the forum I noticed a similar problem [URL] .... and it was fixed through a third fuse box that was not in the manual. I haven't been a user long enough to send e-mails, but it looks like WhipsnHorses was the one that provided the answer before.

A couple times recently, I've been unable to shift my truck out of Park & the brake lights don't work.
After checking the related fuses & finding them to be ok, it all works again.
What might be causing this to happen?

I read other threads about the connections under the hood, both sides, which I unplugged and replugged. I also pulled the IOD fuse for a little bit. Then I removed the cluster and looked it over. Looked good to me.
Got code P1698 for manufacturers assembly control or something to that effect. Thought I checked all the usual culprits. The dash lights work fine, so does everything else. The dash gauges just don't work. This is something that has been an intermittent problem with the dash gauges going out periodically when hitting a bump. It leads me to believe a connection. But I checked all those.

My car sat for 3 months and then I tried to start it. When I turn the ignition on, everything looks fine until I hit the brake pedal and the dash lights dim. If I don't press the brake, the dash light dim when I turn the ignition to crank. Either way the starter either clicks or doesn't do anything and I hear a humming sound. My husband said, "The battery has been charged and measures 12.62 volts," but the cigarette lighter voltage measures 12.26, so they are not the same. I have tried jumping it and I still get clicks.

When I turn left a "clicking" noise appears, it's rhythmic and I figured it was the CV joint at the drivers side going bad. Bought a new one and installed it. Clicking seemed to get away for maybe 5-7 days. Then it occurred again. Because the package in which the cv joint arrived was very roughed up I thought maybe it took damage during delivery and bought a new one. Installed and guess what? Took a drive after that, NOTHING and now it's clicking again. It's so loud you can hear it when you drive behind my truck and I'm turning. Doesn't seem to make a difference if I brake or not.

I have a 97 f150 lariat 4.6L 150,000+ miles, and I am getting a lot of electrical things going wrong, been looking, and found sum kind of electric module could be the issue, except the problem are a bit dif then the ones listed. I am just wondering if it could be my issue. my problems are, 4x4 and low range light come on and off with clicking coming from under dash, daytime lights work here and there, air bag light flashes.
Then this morn my wife went to leave for work and there was a air leak hissing sound coming from the brake pedal area and that was b4 she started the truck, then she said when she got there that the heater stayed on after she shut it off and there was a beeping sound coming from the glove box. I am a general diy mechanic and dont know electrical very well, and i am at a loss.
My steering wheel seems like it is bout to fall off, and when making turns it seems to bind and not wanna turn, but when i try to pull on it, it seems sturdy but it will kinda flop if i go side to side or up and down with it.

I have a 98 f150 Lariat 4wd Automatic with a 2000 4.6. When i turn the key the only thing that happens is i hear a relay in the fusebox in the dash clicking. I can cross the starter relay on the firewall with a screwdriver and itll start right up. Heres what ive done troubleshooting wise.
1. Checked battery terminals. Fine, it will start with jumping the relay so it seems good with that regard.
2. Tested the relay per the manual. Good.
3.Ohms Tested the white ignition switch box under the dash per manual. Good
4. Voltage tested the Trans Range Sensor per manual. Good.
5. Checked over all fuses, none blown.
6. No theft lights come on.
I figure since it will start jumping the relay that the battery, starter, and starter solenoid are all good. Only thing i cant seem to find is the Starter Interrupt Relay, or any sign of fusible links on the main battery cables. I am really at a loss here i figured one of the components ive tested would be it.

I have a 1998 F 150 extended cab and the brake pedal is low. The front calipers and rotors were replaced last year because the left front caliper froze on and smoked the pads. I also replaced the brake booster and master cylinder because the brake booster showed signs of leaking vacuum. The whole system has been bled completely twice. After each bleed, the pedal was high and firm.
I have not found any sign of leakage and the fluid level looks ok and unchanged. The rear brakes look ok, but no work on them in last few years. Mileage is 198k. I had to hit the brakes hard on a muddy road a few weeks ago and the truck stopped straight, so the ABS seems ok. The problem is that the pedal has dropped down a few inches from where it was then the system was bled out. What to check next?

I recently got my truck back from the dealership 04 super d 4x diesel (wife put gas in).. Anyway my dash lights, running lights and brake lights are not working. I checked fuses already and I did not see any obvious problems. I also replace the switch but that didn't work. Perhaps a ground somewhere or a relay? Turn signals and headlights work.

I have a 98 F150 with a 5.4 auto 4X4. All four of the guages are on the left side of the instrument cluster. Neither one of the 4 work. The gas gauge, the amp meter, the oil pressure, and temp gauge work. the all four just stay all the way down. I've checked all the fuses and the sending units. ONly fuse position number 6 and 30 pertain to the cluster. I took the cluster out too make sure it was plugged in and it was. I know there is gas in it and I know the oil pump is working.

Got a 99 f150 4x4. 4x4 use to work perfectly until 6 months ago. Now every time I turn the key on, I hear 5-6 clicks behind the dash (specifically behind the speedometer). This happened right when the 4x4 stopped working. This click is the same sound it use to make when it was working when I would shift 2H, 4H or 4L. (but just one click per turn). I get no light indicators nor click sound when I turn the switch. I've replaced the actuator, solenoids and the switch on the dash itself.
The same problem persists. I have a good vacuum and can see the actuator moving when manually grounding either solenoid to simulate a working 4x4 system. Fuse 23 and 104 are good. I had a semi-mechanic check the GEM and said 90% chance it was good but did come back with code 1838 Transmission Transfer Case Shift Motor Circuit Failure and code 1867 Transmission Transfer Case Contact Plate General Circuit Failure.The secret relay went bad? The wire went bad? Secret 4x4 connector came loose somewhere?

I'm in the process of putting a brake controller and 7 pin plug in on my 98 F150 Super Cab, 4x4, 4.6 L with a auto trans. Got the Tekonsha Voyager hooked up to the existing harness under the dash. I have the 7 pin installed out back and thats where my problem begins. The 7 pin harness came with 3 30amp fuses and 2 relays that need to be placed in the power distribution box under the hood. I can figure out where the fuses go but my manual says nothing about the relays. The relays that are already in the box are for things like fuel pump etc.

Got in my truck this morning and noticed the service engine light, oil light and gas cause were all still on. It also had little dashes in the odometer box. The seatbelt alarm goes off as well. What is going on?
