Suggestions on turn signals from hell??


Recommended Posts

New bulbs, new relays, new fuse box, new rear tailight wires...

 

Signals work for about 100 miles and then stop blinking (or like today stop working altogether.)

 

Can't pin it down, but cops know me and this needs to be fixed quickly. Any suggestions?

they may have a bad or loose ground but the sockets could have gone and if you do a search you may find that we have talked about this issue and there was a replacement socket if memory serves me right it was a ford that would work. But may not be the perfect fit

I don't think there is much left but the wiring itself and the switch on your column. I'd go with bad ground wire or bad socket.

 

Use of your arm is still legal as far as I know. :nuts:

 

left arm out the window works i almost suggested that.

 

elbow at right angle hand pointin up is right,

elbow straight, hand fully extended is left.

 

hand down at right angle is stop. but you've got brakelights right?

I would think bad sockets. I couldn't get the driver side to work on mine so I cut them both off and wired some in off from a 97+ harness, works great now. I have seen replacement sockets at the auto parts store for a couple dollars.

I had a very similar problem with my son's MJ when we bought it. Somehow, the previous owner managed to cram a single element bulb into one of the 1157 sockets in the rear. The single contact on the bottom of the bulb would touch either, both, or neither of the two contacts in the base of the socket. It caused all kinds of odd symptoms- and sometimes it seemed to be working right. I'd look at the bulbs real close and at the sockets in the contact area- if the other ideas don't work.

That one 'bout drove me nucking futz. :mad:

Almost every signal or light related problem I have ever had on any truck usually came out to be a grounding issue. The sockets on these things are a proper PITA. It has a crappy exposed ground strap that travels down the side of the socket, that may look good (mine did) but are rotten near the bottom (mine were). I don't like to splice wires if I can avoid it so I found good sockets at the junk yard and swapped the good ground straps in to my sockets.

One symptom of this was that I had the signal indicator light stay on solid on the dash pod.

I agree. Bad sockets will cause the problems you are describing. If you have the orginal white plastic ones, time and moisture have taken their toll, change the sockets with OEM or aftre market that have the black shrink seals and they should work fine.

Update!

Forgot to mention that the bad socket that is causing your problem is the FRONT socket.

 

Changed both of mine and everything worked fine. As mentioned above, if your dash indicator stays dim lit on one side, thats the bad one.

Mine was doin the same thing, turns out the fuse terminal was not making proper contact; remove fuse & GENTLY push contacts towards each other so as they're griping fuse tighter. Spray electronic contact cleaner before you re-install fuse.

"Even funnyer is" 'Now my headlights don't come on until engine the warms up' -must be corrosion at the relays- ha ha :headpop:
