Turn Signal Problems, Won't work with lights on Options

[Snafu]

Been having a little problem with the turn signals. I noticed that the dash indicator would light both directionals if I activated the right turn but would work correctly with the left turn. Now....they don't light up at all and the turn signals don't work when I have the headlights on. They work fine with the lights off(even though the dash indicator doesn't) I did have a bulb out in the rear and I checked the connections while I had it apart.

This being my first 914, where should I look next?

Anybody ever experiance something like this?

Thanks in advance!

Did you ever figure this out. I have the same problem with both inside flashing.

[Tobra]

Both arrows on tach flashing is normal when R or L signal activated. Working then not working sounds likea bad connection.

Don't know about not working with lights on, is this a new development.

Does your 4WAY flasher work? All 4 bulbs should flash! front and rear if they don't
change bulbs first then check the grounds connection next. Let me know what
happens.

4 way flasher doesn't work. Now dash indicators don't either.

Weird thing is The worked for a second then I turned the headlights on and pulled the flasher....lights got dim.

Flashers, turn signals don't work at all now.....

Locate and repair the ground connections for the affected components. Work the emergency flasher switch rapidly and repeatedly (like 10-15 times) ....... It gets corroded inside. Can't hurt! The Cap'n

weak ground (IMG:style_emoticons/default/thumb3d.gif) thats why they work w/o lights, to much currnt draw with extra load-

[904svo]

Check the connections at fuse #11 thats where it get it's power from then check your grounds, also make sure that the red wires on the + battery post are good
and clean they go to the fuse block.

[Snafu]

I checked all connections. Negative was loose at battery. Still no signals. Hazards don't work either.

Bad relay maybe?

[904svo]

Check the ground connection in the upper left corner, under the dash, its a bundle
of brown wires , remove it and clean up that connection and reattatched, these are
the ground for the dash. The flasher relay could be bad also. If you find any Brown
wires loose reattatched them to a ground.

Im going to try this to....
I have the same thing going on in my car exactly the same.
But when I hit the brakes the left front blinker lights up. WTF?

its always good to us a little di-elctric grease also -good for long term contact-

i'll bet you'r curcuit is seeking a good ground and finding (backfeeding) through turn switch or whatever route to your front blinker. i've experienced (chevy trucks/faulty ground on front exterior light sockets) doing almost the exact thing (front blinkers would seek ground thru dash turn signal gauge lights/interior indicators would both light up but outside wouldn't)

Well I finally got around to working with the car today. I pulled the fuse panel down and checked all the connections and I noticed that the turn signal fuse was blown. I don't know how I overlooked it. I also noticed another wire that is fused coming from the the turn signal fuse going under the dash too. I checked that fuse to find it had blown as well so I replaced it too. Connected the battery again and heard a "pop" sound. Found the inline fuse of the "mystery wire" had blown again. Needless to say I went through a pack of fuses. Another thing I noticed was that the left (drivers side) marker light and turn signal light were brighter on that side...

Any ideas?

Any ideas?

Fuse#9 should have 3 wires on it, black/yellow to brake light switch, two red/white
one goes to the EM flasher switch the other to the GEN light bulb. Remove the wires one at a time and see which wire blows the fuse. Remove the fuse from the mystery wire and see if your lights work, if so trace out the mystery wire and see
where it goes and let us know.

I removed the fuse but the flasher/signals still don't work. I'll give your suggestion a try. Any ideas as to why the driver's side marker light and turn signal light are brighter than the other side?

This is normally a bad ground or bad bulbs on that side.

Do these steps and let me know what happens.
1.
With Key off!
left turn signal on= front and rear marker lights on
right turn signal on= front and rear marker lights on
This is a quick check of the grounds for each light circuit
2.
turn signal switch in netural
turn on parking lights=front and rear lights on
this checks the power and wiring to each light
3.
Turn off parking lights
Turn on 4 way flasher
this check power and the flasher.
4.
Turn off 4 way flasher.
Turn on key!
step on the brake pedal= rear brake lights should work
this check the fuse and brake switch
5.
Check turn signals now, they should work
if both turn signal indicators lights light this is telling you
the bulb for the other side is burn out or is the wrong type
bulb installed or the flasher is bad.
Note. Turn signal inducator bulbs use the bulb for the other side for ground
to light it
6.
Apply the hand brake= brake light should flash
checks the switch on EM brake and flasher

If any of these steps fail,

FIX IT first before doing the next step

Replace any bulbs recently? Putting a single-filament bulb into a socket for a dual-filament bulb will make Very Strange Things happen to your car. (Like: it keeps running after the key is off, but only when the turn signal switch is down!)

The front turn signals should have dual-filament bulbs in them.

I had a similar problem, weird stuff changing with key on and switch selections. After hours of chasing wires (IMG:style_emoticons/default/headbang.gif) it turned out to be the relay.

Nothing.

2.

lights work


3.
Turn off parking lights
Turn on 4 way flasher
this check power and the flasher.

Blows fuse

doesnt work
4.
Turn off 4 way flasher.
Turn on key!
step on the brake pedal= rear brake lights should work
this check the fuse and brake switch

works

(IMG:style_emoticons/default/sad.gif) nope
