Ford Excursion :: No Signal / Flasher / Brake Lights - Truck Is Too Week To Start
Dec 10, 2016
My 2000 Excursion 7.3 Limited started something all new this week. No brake lights, signal lights or flashers. The signal flasher relay is only a couple months old, but I don't think that's the issue. If I sit for just a moment with door open or park lights on, the truck is too week to start. Batteries seem fine and ALT is 14 volt charging when running (ALT replaced with used ALT about a month ago). Further, it has started having long starts like the glow plugs are not cycling. Any clue as to what might be going on?

I have a '97 AWD and my brake light, turn signals and emergency flasher have stopped working. I've checked all the bulbs, checked all the fuses (under the dash) replaced the flasher just in front of the fuse box...nothing. All the running lights work, and the 3rd brake light above the rear door window works.

I towed my friends car hauler yesterday for a short distance for him. I had no turn signals or 4 way flasher while towing. After dropping off the trailer still no signals or 4way flasher. I parked and checked fuses all were good and signals started to work. But still no 4ways. Any thoughts on what to look for. Never had this before. I have blown a fuse before and always been able to find and fix.

Turn signal flasher doesn't work in the heat. What gives?
All lights work. Turn signal stalk works fine. It just flashes a couple of times, then stays on. Everything works fine in cool weather, but it rarely works at all when the temperature outside is above 90 degrees. Very annoyed.

I have a 2003 V10 Excursion with an electrical problem. The right turn, right brake and right hazard light do not work but the flasher makes the clicking noise. When the right turn signal is on, the right front turn signal light works but is at double speed. The right rear light does not work. Same when brake and hazard are applied.
I checked the bulb socket with a multi meter and have no current. I also checked my trailer plug and have all functions work. Fuses were checked also for the brake circuit and were all ok.

the wifey went out to the Ex this morning to make a coffee run and came right back in. "truck won't start" hands me the keys. So I go out there and turn key, ALL lights and power comes on but when you try and crank it there's a tiny 'click' and then NOTHING AT ALL. Alternator's brand new and so is the battery (less than 2 months old).

A friend of mine has a 2004 F150. The tail lights and the 3rd brake light are working but the rear brake lights, flasher and turn signals have stopped working. What could be wrong? I googled the problem and did find one person with the same issue in a 2001 F150. There apparently was a recall (#05S28) of the SCDS (Speed Control Deactivation Switch) but that vehicle kept blowing fuse 13. My friend checked his fuses and they were all ok,

My 97 F150 4X4 's turn signal flasher buzzes all the time except when brake is depressed or turn signals or hazard signals are active. The flasher is a 5 prong one. What to check?

Where is the signal flasher relay located. I can hear it but can't track it down.

I've got a 2001 f150 supercrew 4x4 with the 4.6. I plugged in trailer lights and now I have no brake, turn signal, or hazard lights. I've checked fuses and none are blown.

2013 F250 XL with factory towing package.
My camper and boat trailer do not have turning signal or brake lights when plugged into the round seven pin trailer connector. I have tried both the connector in the bed and under the bumper. I've also connected the trailers to other trucks and the lights work fine so I know the problem is in my truck.

I'd like to put in a louder turn signal flasher on my 2007 F150 - where is it located and where I can get a louder one ?

Exactly where that part is, pictures would be useful. Pretty much just had my whole dash apart with no luck. Switched to leds, and can't stand hyper flash like I thought I could. Trying to pull it to make sure I order the right part to correct it.

I'm having an electrical issue that is driving me nuts. I have an '01 F-250 Super Duty that I just put a new battery in today. The truck normally runs great, I drive it to work everyday with no issues. Today, there is a noise coming from under the dash that sounds like the turn signal flasher, and the clock on my radio flashes in time with the noise from under the dash. All my lights are working ok, and all the idiot lights come on as usual when I put the key in the ignition and turn it to the on position. However, my truck won't start. It won't even turn over. I get nothing but a dead switch when I turn it to the start position. The starter solenoid doesn't even click. Like I said, yesterday everything was just fine. I knew my battery was going bad (6 years old), so I changed it.

my 2005 V10 Ex is garage kept. I work at home and have a different daily driver so it usually goes out once a week.
At 40,000 miles and 10 years...it still has the original factory installed battery. I keep a tender on it if it's going to sit a while and so far everything has been OK.
At 10 years, should I replace the battery just to avoid a potential problem?

2015 prius package 5 w tech package and HUD display, I found a flasher mounted up between the fuse box/ module assembly mounted on a clip! I have a led replacement flasher, but clip mounts and pin locations don't line up? I watch the video but I have nothing in area! Or I just need to install the resistors? Or it could be a combination circuit assembly where multiple function module all in one ?

So with 172,000 miles my truck has started a new trick. When I turn on the turn signals theyll flash or interrupt normally for a few times then stop. After I turn the signal lever off and back on again they start to flash again only to stop after several times. This happens to both the left and right hand sides. The emergency flashers seem to work alright. Is this a function of the indicator flasher SF631? If so, were exactly is it located?

2003 X limited, 2wd 6.0L
Last week wife's right rear turn signal/brake light stopped working. The left one flashes normally. The right tail light works fine which is a different bulb. I tried changing bulbs (didn't work).....tried a new socket with new and old bulb (didn't work). Could it be a relay? Or not relay as they would be both out (left and right)?
I looked at my trailering wiring plug down by bumper and the white wire with green stripe looks split a little towards the end. Could it be a bad ground or short in that wire? Would the trailering wiring have anything to do with it? I was going to try to replace the relay if I could find it, what is the part number for it.

It only does it when it is fairly cold out and when it sits overnight. I will get into my 2000 4.0 Explorer and when I put my foot on the brake my right side turn signal comes on, it doesn't flash it just comes on and stays on. When I let off the brake it goes out. It will do it maybe four or five times and then work fine all day. Its just the right side and the indicator on the dash comes on too. I haven't looked at a wiring diagram yet to see if there is a connection between the two.

I want to install some LED turn signal bulbs and lights but the flasher will flash twice as quick because of the burnt-bulb detector.
I have taken the flasher apart and tried all the tricks on the book to isolate each pin on the IC and changed the timing resistor without avail. I do not want to put in load resistor on the bulb end to fool the detection circuit.
I want to modify/cut off the detection circuit?
