The turn signals on my truck do not work, though when I turn the harzard switch on the lights blink. I know its not a fuse. What is wrong with my truck and how would i go about fixing it.

need to check your vehicle's turn signal flasher relay, located on passenger compartment fuse block. if relay is OK , suspect faulty turn signal (multifunction) switch. This guide can help us fix it

Please run down this guide and report back.

There are 2 different flashers, are you sure you replaced the right one? When you engage the directional do the lights illuminate but not flash or not illuminate at all?

As of yesterday, my front right turn signal quit. When you turn the right turn signal on, the rear turn signal illuminates but does not flash. If you turn the hazard lights on, the right front still does not illuminate. Also the indicator on the dash does not light up at all. The bulb is good. The parking lights work properly. Can anyone help diagnose the problem?

if anyone is interested, the turn signal switch was the problem. I jumpered the wire from the switch to the bulb to ensure it was all working past the switch. I replaced the switch and it works great.

When I turn my turning signals on, they do not flash or blink, the lights outside come on, but they don't blink, but when I turn on my 4 ways or hazards, they blink? Please help.

your turn signal flasher relay has failed. you will need to replace it, it is located on the front of the fuse block

I am having an issue that is puzzling. front right and left rear work when I attempt to use those, however the front left and right rear do not. What puzzles me is that the hazard, when engaged causes all 4 to flash. I flipped the hazard and turn signal fuses and nothing changed. so what gives?

as each bulb has two filaments one is obviously blown in each bulb. You will need to replace them. buy 2 1157 bulbs.

I tried this today and it made no difference. In fairness I believe the last owner altered the fittings as they now accept 3157. Additionally, the left/right switch does not lock in position

3157 is just a newer style bulb. You need to buy a test light. Check to see if your getting voltage at the sockets when the lever is pushed up or down. You will also need to replace the turn signal switch. But let's get the lights working now.

If the socket fails the voltage tests what shall we do? I'll be testing it soon.They did, I'm tracing the wiring, almost have the rear located, as for the front. Not so easy.

so you're not receiving a voltage signal to the wires right behind the socket?

I've received input for parking and hazard lights but not turn, the black wire is receiving an overload error on multi-meter.

Good evening,

Switching fuses does nothing.

The difference is the multi function switch. It has different contacts with 4 ways than it does with 2 way or just turn signals.

I attached the wiring diagram for you to view. I would replace the turn signal switch.

Hi,

I read through your post. As a result, I opened up the wiring schematic from Ford it look at the signal lighting circuit. Based on what I am seeing, this isn't an issue with wiring causing two opposite sides not to work. Interestingly, the hazard lights, which you indicate work, use the same wires, but they are switched from a different location. Based on that, I feel ASEmaster is correct. If you look at the first two pics below, you will see how the signal switch has four different contacts. I suspect that is where the problem is located.

Here are a couple links you may find of interest:

If you determine it is the switch, here are the directions from Alldata.

1989 Ford Truck F 150 2WD Pickup V8-302 5.0L
Turn Signal Switch Replace
Vehicle Sensors and Switches Sensors and Switches - Lighting and Horns Turn Signal Switch Service and Repair Procedures Turn Signal Switch Replace
TURN SIGNAL SWITCH REPLACE
1. Disconnect battery ground cable.
2. Remove horn switch, then the steering wheel.
3. Remove turn signal switch lever by unscrewing from steering column.
4. On 1987 models, remove lower steering column shroud. On 1989-91 models, remove upper and lower shrouds.
5. On all models, disconnect electrical connector from turn signal switch and remove switch attaching screws.
6. On models with tilt column and Bronco with fixed column, remove wires and terminals from steering column electrical connector, after noting color code and location of each connector. Remove plastic cover sleeve, if equipped, from wiring harness, then lift switch assembly out through opening in shift socket.
7. On models with fixed column except Bronco, remove switch assembly by lifting out of column while guiding connector plug through opening in shift socket.
8. Reverse procedure to install.

Thanks for replying. Yes it's just the front right. The park breaks work. Also when I turn on the hazzard lights the left is out, so I take it that it's on the same switch or something.

they run thru the same wiring.

with the left blinker on take out the bulb and probe with a mutimeter from the ground side and the power side for the bulb and tell me what the meter reads in the front even if it gives 2 different voltages tell me both

Welcome to the forum, use a testlite check for voltage at the turn signal circuit. Right rear, orange wire with lite blue tracer should be voltage for that turn signal. Key on, right turn activated, see if any voltage? If you have voltage, check ground. I'd check all bulbs and bulb sockets. There is also a turn flasher in the fuse box, that could cause a problem, as well as the turn switch.

Directional lights not working.
I replaced the flasher relay and turn signal switch.
Fuses are good. Hazard and brake lights work. Is there a different bulb that may be burnt out or could it be something else.

Thanks.

i would really have someone help you chack all of the bulbs first , then check the signal flasher and relay the hazard and turn signal should be the same try swapping them out , start simple dont replace parts unless you need to , if you need more help just post back here , i will get an email when you do

thanks

There is another fuse box under the hood. This "power distribution box has a combination of fuses and relays. Check for a blown fuse there. The fuses here deliver power to the fuse box in the car. there are many fuses that control different inside fuses.
On my Explorer, it is fuse #3. Check your owners manual.
