Blinker help....please read

[Wreck]

Yes I know there are a ton of threads on it and YES I did search (for about three hours) and have not found a thread with my problems...so here goes, To start out with I have three of the four lights working properly except the front passenger turn light. With the lights off it seems to blink at a normal rate, but it is very dim, the back passenger light is normal brightness...when i turn the lights on the right turn indicator stays on in the dash (not dim like everyone elses) and I have no park light on that side (just in the front the rear is fine)...when I turn on the blinker it is very slow and is not as bright as the drivers side blinker. Also the side marker does not light up with park lights in the front and it blinks in unison with the blinker....the driver side side marker alternates the blink with the blinker and is lit with the park lights. So it seems all my problems are the front passenger light, probably wiring..well I checked and rechecked all that and compared it to the wiring diagram and all seems to check out..I did find out that the side marker was wired into the same wires as the blinker (so that explains the side marker problems) but then I cant seem to find how that side marker is supposed to be wired, possibly that whole wire is missing, but I cant find it cut anywhere....also I took the lenses off and turned on the blinkers..the drivers side blinks with the short element and the parks is the long element..the passenger side the tall element blinks (very dim and is the wrong element) and nothing happens with the short one(1157 bulb)...when I turn on the flashers everything blinks together, but the passenger is is not blinking with the same element as the driver side..it seems that this light is backwards or something else.....here is what I did, changed all bulbs, switched the wires to the pass blinker, checked and taped questionable wires, found as many ground in the engine bay and tightened them, checked the flasher relays (swapped the haz and blink) checked the floor high/dim switch, checked the wiring to the back....could the switch in the steering colum have anything to do with this..it is broke, but it still activates the blinkers, I just have to manually put the blinker lever to the middle........anything else I should check??

Sorry this is a long post, but it is just one of those probs that is just driving me nuts

I had a similar problem and found it to be my stop light switch located under the brake pedal. It wasn't tightened enough to close the switch. Check that.

It may be the socket in the park light assembly. I know it's a lot of screwing around, but try switching the complete assemblies, left to right, and see if the problem goes to the left side. If it does, then the problem is the assembly...if it stays on the right , then you still have an electrical problem. It really does sound like a ground problem in the right park light assembly. The ground is in the mounting screws, into the outer grill, and then to the core support. Try turning the park light screws out, and back in a couple of times to clean the threads.

It sounds to me like the turn signal is being grounded thru the side marker light. Fugure out why the side marker light won't come on & it will probably fix your signal problem. Also you might want to take out the side marker bulb & see what happens. Another try is take the turn signal housing out of the good side & swap it with the bad side. What I'm getting at is a process of elimination. Eventually you'll get it...........Zoomy

I can't answer where the actual problem is...but it is a ground problem for sure.

[Wreck]

thanks fellas...you give me a couple more ideas.

sounds like the phenolic disk in the socket is rotated from its corect location

[krue]

phenolic... now there is a 50 cent word!

Are you sure you don't have the wires swapped? I replaced my socket and it did strange stuff, then I swaped wires and it worked properly.

it's low on blinker fluid......J/K

I had similar problems in my 68... it was corrosion in the sockets.
My 71 has a problem with the right front turn signal... when the lights are on sometimes it just won't come on in the running light mode... and my turn signal indicator stays on... I hit a bump and it'll will start working...not the best for the old suspension... but the light comes back on.

i had some of the same prolbems on my blazer this weekend..ended up the dieletric grease was holding
dirt under the sterring wheel where the turnsignal
conecctions are,cleaned them and the flashers and signals on the blazer worked.

btw use a battery top post cleaner to clean bulb sockets ..works great!!!!
good luck

I had the same problem, the socket was loose in the housing where it crimps in, loosing the ground. You can check it by using a screw driver pressing against the socket and housing. Good luck

[Wreck]

thanks guys...got it fixed, it was the ground, all working good.

BE SURE THE LIGHTS ARE OFF!!!!!!
I saw an idiot do that with the light switch in the on position. Talk about funny! (his reaction....not the damage done)

A friend had some strange lighting happening on his 75 truck. We finally found an 1156 in a 1157 socket in the back. Very strange.
