hello! Thanks for the add

I just acquired a 1983 ford 2wd 460 from the original owner , hit the lights on and every marker , rear and front light work, fuses test good , I replaced the blinker relay(on front) and the hazard relay on the back. It has a 7 prong trailer plug for a gooseneck

i have no blinkers or hazards , no sound from relays nothing on the dash ,

I tested power to the relays they are good , and power coming out ,

would bad grounds at the lights cause them not to flash ?
Why would brake / running lights work if they use the same bulb and flashers/blinkers not?

How do I test if it's the switch in the column?

Sorry thank you !

 

You should put ALL your truck's details & history (as much as you know) into your signature so it shows with each post, as this page explains:

Phone apps don't always show signatures, so you may need to switch to a real browser in desktop mode on your phone, or just use a desktop/laptop computer. Put your location (nearest city) in your profile &/or signature, & upload an avatar of the truck. The more pics you post (NOT in your sig) of the truck, engine, wiring, labels, & undercarriage, the more likely we can help you. Not all its details are relevant to these issues, but you don't necessarily know which ones are relevant, so just put everything in now.

Those aren't relays - they're flashers. Yes, the flasher & bulbs only work if the circuit is complete, and the exterior lights all use the body & frame as grounds back to the battery (-) post.

The brake lights do not use the flashers. And although some of the bulbs are used for both functions (park and brake/turn/hazard), they also have 2 filaments inside, so it's almost like 2 bulbs. It's very important to notice exactly what happens when the park lights are ON, and then the other filament is used. An easy way to check is turn on park, and then turn on hazard, so you can walk around and study each one closely. Does the light change? Does it get brighter when the hazard flashes on? Does it get dimmer? Or does it go completely OFF? Check at night so you can really tell.

Yes, the turn/hazard switch in the column is known to be problematic. But it can usually be cleaned by cycling the hazard switch on & off rapidly several times.

 

I think I got the signature , and the pic I have I'll take much more in a bit I'll also check lights tonight and get back to you thanks for the reply
I have tried cycling the hazard and switch going to spray with contact cleaner

fired it up today and lost power brake on pedal and brakes are locking up when I barley touch them so may need a booster or master cylinder, or rubber to wheel probably all three haha

 

After it gat dark here I had my brother in the cab cycling the hazard switch and I was walking around observing the lights ... boom my brother says hey it's making noise !
I had him keep going , I was seeing no different on the lights so far , then he got lights on the dash... boom I started getting all 4 . he let go of the switch and front lights stop , back continue , no lights on dash, flasher still clicking . I got in the cab and figured out you have to hold it all the way out or kinda pull it this way or that to get all four lights, everything is nice and bright,

still no blinkers!!!

you think this now confirms the switch in the wheel is bad?

maybe dirty?
should I still try contact cleaner?

 

Are you just guessing? Shotgunning part$ at it? That's not likely to fix anything - it'll just help your parts seller retire. When you identify a problem on the truck, the first step in fixing it is to LEARN how that system works, and then figure out why yours isn't working that way. Follow the links on this page:

The autoadjusters inside the '83 F250 drums are different from 1/2-tons, but the rest is similar enough for that to be applicable. AFTER you know why yours isn't working right, you can decide how best to fix it (with the FEWE$T PART$ & wasted hours).Yes, that's definitely a failing hazard switch, which is integral to the turn/hazard assembly. If contact cleaner (don't use brake or carb cleaner) doesn't work, read this page:

by no means am I a parts changer and
"hope it works "

, looks like I have the new book

I have run into this issue before In a 79 Chevy and it was the rubber line to the inner wheel , the liner was bad would let fluid in but not out , the truck has been sitting for 5 years or so I only say all three because it probably would be safe to change them all. I will do the correct test to figure out which one .

I'll use contact cleaner tonight on the column

 

Contact cleaner got the hazard working great all 4 nice lights in the dash , but still no blinkers .... what's your thought ? I swapped the fuses and test lighted it all just in case if I pull out the blinker flasher good power to topside of the flasher .
looks like a light blue wire on bottom of harness coming out of column should be power out of column?

the issue with the breaks is only the driver side rear , just freezing up with or without break so I will need to take the wheel off and investigate

 

Also figured out it's a tilt wheel , I can't find a new harness for tilt just a plastic cam Dorman part #49301 is this the way to go ? Or is there a full harness somewhere for tilt

 

The HELP! part is absolute garbage.

Yes, the tilt turn/hazard switch is available, but probably not from Ford/MC now. Start at RockAuto, but search their PNs on Amazon/eBay/OReilly/Advance/etc. (stay OUT of the zone) for the lowest delivered price in the time you have.
