My right turn signal has been out for about 3 months(lazy)you know how ya know when youre inside signal blinks at the speed of light.anyway today I changed out the bulb. the bulb was not blown just wouldnt blink. so I took the left turn signal out(that does work) and put it in and still it would come on but not blink. I took the back tail light bulbs out and they are fine also..What could this possilby be?

I have replaced the Hazard switch as well!

 

revive this issue.

I have the same exact issue.

Right side turn signals failed and we tried switching out the hazard to no avail...

Swapped bulbs side to side and that didn't help either.

 

If the light is on all the time the relay is probably stuck in DRL mode either because the BCM is not shutting it off when the flasher tells it to or the relay is no good. Try swapping out the left relay for the right one (#s 38 and 40 in the footwell fuse centre) to see if that makes a difference.

 

out standing tip for knowledge base tank you hope it helps him

 

thanks for the idea

we'll check it and get back

 

well that didn't do it...

any other thoughts?

I think we're down to tracing wires from the front to back...

 

Is the light on when the ignition is on (ie DRL)? If not then yes , you probably have a wiring issue. If it does come on when you have the ignition on, shut the ignition off, pull #2 fuse(Approach) under the hood to disable the DRL function then see if the turn signal works.

 

Tried that, and it didn't work either...

I hate electical gremlins....

Thanks for all the suggestions so far!

 

If you pull the micro-relay,the slots in the panel are arranged as:
2 4 5 across the top and
3 1 across the bottom (verify with the pin #s on the relay)
1 and 5 should always be hot (come from the approach fuse),2 is ground only when the key is on,brake off,etc.(for DRL) 3 goes to the signal light, and 4 comes from the hazard flasher. You can bypass the whole DRL setup by leaving the relay out and jumping 3 to 4 with a short wire. Does the signal light work then?

 

I guess I never mentioned that its the rear 2 lights that are not lighting up. The front right turn signal flashes at double time, indicating less resistance in the circuit.

The brake lights and the tail lights work, and the light shuts off when the blinker is engaged for a right turn. So it seems as though the BCM is telling the tail lights to turn off so that the blinker can go active, but the blinker just isn't sending power to the back.

I'll try your suggestion tonight and see if it helps. Once again I really appreciate the help.

Jay

 

Still blinks fast in the car and tail lights---the front still does nothing at all!!
Could it be the turn signal malfunctioner switch?
I used to be able to spray contact cleaner in the steering colomn and it would work for a little while. Now pretty much nothing.
Thanks for the input

 

Hmm--just did this and now the right one now works and the left one does not!!! Should I just replace the relay switch?

 

i had the same problem with the left side. i replace the bulb work for an hour and go out again so i took the bulb out took a small flat screwdriver and close the contacts in the bulb sucket,so the bulb make a tide contact and my problem was fix."]dont make my mistake the signal light was on and i pop the fuse keep the car off or take the fuse out . [COLOR="Yellow"]it took me 3 month to figure it out.hope it help you too. also remember to do it slowly to prevent the metal contacts from braking. [/COLOR][/COLOR]

 

Yup, the relay is your problem.

 

Auto Zone or Advanced carry these by chance

 

Sorry, I don't know, I'm up here in Canada. But it's the same relay as in my 97 Silverado so I'm sure they're pretty common.

 

Sorry, Jay, if it's the rear lights that aren't working I've been giving you some useless information. The BCM and the #38 and 40 micro-relays are only involved with the front signal lights. By sending or not sending a ground signal to the relays, the BCM either turns on the front signal lights as daytime running lights or turns them off, allowing the signal light function through. They are not involved with the rear lights. I haven't worked with the rear system yet but the service repair manual says:
-remove each right rear bulb,connect a voltmeter between each signal light socket terminal(dk green wire) and ground, turn the signal lever on, and measure the voltage.
-if it alternates between 0 and 12 volts, shut the signal off and measure for continuity between the ground terminal of each socket(black wire) and ground. If it's open find where the wiring between the socket and ground401 is interrupted(numerous electrical problems relate to corroded ground splices) and repair it. If it's continuous, try a different bulb or make sure the bulb is making good contact with the terminals.
- if it does not alternate between 0 and 12 volts, trace the wire back to the wiring connector C209 and check fo alternating voltage at the dark green wire terminal there when the signal lever is turned on. If still not, it suggests replacing the turn signal switch.
According to the wiring diagram, working backwards from the taillights the wiring goes to the turn signal switch, then to the hazard warning switch, then to the hazard warning switch or stoplight switch.
Sorry, that's all I got.
Jay(coincidentally also!)

 

Thanks! It gives me more things to try, and at this point its a ray of hope. I'll keep my baby out of the stealership as long as possible.

 

--Good info BTW

 

ya got me so confused with symtoms. spraying something used to fix it?what ever you sprayed may be the problem. hot tip if you think its the sig switch and ya buy one first find the jack under dash for switch unplug it and plug in new switch if ya still got problems dont r+r the switch . its youres though no return on elect items. at least ya didnt have to replace the switch. please let all of us know the cure and maybe better symptoms tank you and good luck
