Default 89 LE: Left blinker turns on, but no longer blinks

What causes a blinker to still function, but it doesn't blink? Would this be a fuse issue? It turns on, I can see it'* reflection against other objects, however I need to manually flick it to signify that I am turning left. Right blinker still functions normally. This only occured 2 days ago.

i would almost be willing to bet money that one of your light bulbs is out. turn on your hazards, and walk around the car. you should see it. cant be the fuse because the right turn works fine. at least i dont think

I have this same problem occaisionally. My left signal will stay solid, and not blink. I went around and checked when it was on. Solid light. The light on the dash doesn't illuminate at all. I've been told it'* a grounding issue but don't hold me to it.

There was something shorting on my car that had me do this. I honestly don't know what I did to fix it. I just know it works fine now. Betcha it'* your turn signal switch. I'll check my FSM today and see what it pulls up.

lets not count out the possibility of a bad relay. I've never seen my turn signal switch relay but i think its safe to assume that weall got em in there and that it controls the flashing. But yeah i'd Definetely suspect a bad bulb before suspecting a relay or anything else.

But if the light stays solid, the bulb is fine. If it'* the bulb in the I/P that won't affect the operation of the turn signal.. at least I don't think so. After looking at my FSM wiring diagrams, I don't see anything that makes them related.

Perhaps it could be that the IP bulb is burned out, and that having that bulb burned out has the same effect at a burned out bulb elsewhere in the circuit? Of course, it could also be a bad connection for the same.

I think that usually if a bulb is burned out, the dash light still works. And if there'* a bad connection, it would act the same as a burned out bulb (the bulb on the affected circuit wouldn't light, but the dash light would).

If the blinker unit was dead, it would be for both right and left, so I think we can rule that out.

I think not the turn signal switch itself either, since the lights do actually turn on and off with the stalk, which is all that the switch there actually does.

That'* my rambling $.02

rjolly: Not everyone has an SSE, bud. However, I believe SE'* have a bulb monitor. LE'* don't, I don't think?
