    What am I getting into trying to access the wiring from the top and bottom? Where does the turn signal wiring through the column terminate? Any thoughts on what color wires I'm looking for once I get to them? I'm still a little confused as to why I'm not even hearing a clicking noise. Is it just an electronically generated tone like the newer GM's?

  • john berthiaume Nov 14, 2010

    Something I forgot to mention was that the lights for the turn signal indicators on the instrument cluster DO light up when the 4 way flashers are used . Where might one find the turn signal flasher unit?

    Also, aren't the fuses located in the drop down panel inside the glove box?

  • john berthiaume Nov 14, 2010

    something else I forgot to mention regarding the turn signal indicators in the cluster not working was that they DO illuminate when the hazard flashers are used. Don't know if it makes a difference.

  • john berthiaume Nov 15, 2010

    If you don't mind I would appreciate seeing the diagrams. I don't mind taking something apart if I can see why. The diagrams would be GREATLY appreciated. Did you see the added info regarding the fact that the green signal indicators DO illuminate when hazard flashers are used? Don't know if it makes a difference or not. Thanks

    Tested for voltage at the yellow/red wire with the turn signal switch plugged in. I'm reading 10.4 - 10.6 volts whenever the key is on, regardless of the position of the turn signal switch or high beam switch. Checked voltage at cig lighter and found to be 12.0 volts. Did this just to confirm voltmeter accuracy.

    Here's the strange thing I stumbled on. If the car is started with the turn signal switch already in the left or right position, the corresponding signal will flash on the cluster and continue until the car is shut off regardless of what position the turn signal switch is put in after starting the car is started. Outside lights always follow the position of the turn signal switch properly. For example. Put turn signal switch in the right position and start car. right cluster indicator and right turn signal (outside) will flash. leave car running and switch to left turn signal. right indicator in cluster will continue to flash but left turn signals (outside) will flash.

    Is it possible the ground on the brn/black wire (terminal 10) has been lost? Is there any chance of damage if I try to short that wire to ground, since it appears to be a ground anyway? Also sometimes if the car is started with the turn signal already switched either left or right that cluster light will continue to flash even after the car is shut off and the key is removed, the only way to stop it is to turn on the headlights. Also noted the high beam indicator acts the same way. turn headlights on, put on highbeams and start car highbeam indicator will come on and stay on till car is shut back off regardless of what is done with the highbeam switch or headlight switch. Oh yea, and by the way, about every 25-30th time going through all these scenarios everything works like it should...until the car is shut off and restarted then it's screwed up again. Maybe I should just get to one of those starts when everything is working and just leave it running forever. Too bad gas prices are going up... Any thoughts on what a CCM is going for these days?

    The indicator lights in my Suzuki Wagon R+ 1997 model work OK (both outside and on the dash). However, the clicking inside the vehicle stays on, most of the time, even after the indicators have been switched off. (The indicator arm, for some time now, was feeling loose, but a rubber band seemed to have fixed the problem until now.

Hello rbflyin. This is a fairly common problem in BMW's after they have been in service for a few years. The problem has to do with the flasher relay getting a wee bit weak due to the fact that it relies upon a spring which looses a bit of it's strength over time.

You can replace the flasher relay or if you enjoy getting into a rather fun hands on repair go to this link to read an excellently prepared step by step tutorial on this issue. Joe

HI!!
I don't think you should go that far, If you provide an email address I can send you the diagrams you request, but, I think your problem is the Turn Signal Switch or the Cluster Control Module (CCM).

To check it out, look for the Yellow w/Red stripe wire going from the multifunction switch to the inst. panel this is the turn signal/low beam indicator that shows on the cluster All you need is a test light to check it out.
If when the turn signal switch is activated and you do not get any voltage to it, the turn signal switch is defective, if you do get voltage, the Cluster Control Module is defective. If you still need the diagrams, let me know.
A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.

First thing to check is the instrument cluster fuse located underneath the driver side steering wheel. Remove the fuse box cover lid and you will find a diagram that show what each fuse controls. Replace the instrument cluster fuse with the same number fuse. Next, check your flasher unit for continuity with a multimeter. If your flasher unit relay is good then replace the light bulbs inside the instrument cluster.

My rear turn signals are not working. front turn signals work rear parking lights work brake lights work


In the diagram for rear lamp, the top wires are voltage, the bottom black wire is ground. The brown wire on either side should be tail lamps, goes hot when you turn on the headlamp switch. The other top wire on either should be for turn signal. With everything turned on, is there voltage on that wire?
Because the front works and the rear don't, possible wiring circuit problem? The voltage for turn signals comes from bcm. The bcm knows when you turn on turn signal switch, either side, then the bcm sends voltage to turn signal lamp at the rear and front.

I have an 02 kia sportage. my signal lights come on but dont blink outside. no lights for the signal lights come on on the dash at all. also, no hazard lights.


If the 15A HAZARD fuse in the passenger compartment fuse box is OK, power is getting to the hazard function of the flasher unit. Pressing the hzard switch should cause the hazard lights to flash. HOWEVER, there is an electronic time and warning indication system module connected to to the hazard switch lead and that may be affecting things. If the 10A TURN fuse is OK, power is applied to the turn switch (with the engine in START or RUN) and you state you can select a right or left turn. HOWEVER, the RED/WHT and RED/BLU outputs from the flasher unit connect directly to the front and rear turn lamps and the instrument cluster turn indicators so you are not getting any flasher output. Again, that electronic time & warning indication system module could be affecting things

My left rear turn signal is out on my 2006 Malibu. The bulb is good, but I replaced it anyway since I had the assembly apart. The left front flasher works fine as well. Before I try and replace any...


Stop lamp an hazard lights work ?
The body control module (BCM) is responsible for controlling the turn signals and hazard lamps. When the turn signal switch is placed in either the left turn or right turn position, the BCM receives a signal from the turn signal switch. The BCM then sends an on-off voltage signal to either the left or right turn signals and their instrument panel cluster (IPC) indicator. When the hazard switch is pressed, the BCM receives a signal from the hazard switch. The BCM then will send an on-off voltage signal to all the turn signal lamps. All the turn signal lamps will flash including both IPC turn signal indicators.

Repair an open, high resistance, or short to ground in the inoperative turn signal supply voltage circuit. Refer to Circuit Testing and Wiring Repairs .
Did you complete the repair?

1260 code wont start


P1260 - This, basically is indicating that a theft has occurred, and the engine has been disabled.If the engine stalled, during travel, and the code was pulled after the stall, this will indicate the following:

1.A loss of power, or ground wire to the PCM
2.A Faulty PCM power relay
3.A Faulty EEC power diode
4.A Faulty VERF signal.

Passive Anti-Theft System (PATS) communicates PCM through instrument cluster to enable or disable vehicle's engine. Within one second after engine start, PCM must receive an enable signal from instrument cluster or engine will be disabled. Along with enable signals, instrument cluster and PCM share messages that confirm security codes shared during initial installation. This shared security data makes instrument cluster and PCM a matched pair, so neither will operate in another vehicle. When system is functioning properly and ignition switch is turned to RUN or START position, THEFT indicator light will turn on for 3 seconds, then turn off. Vehicle will be enabled to start and run. If a problem exists in PATS, THEFT indicator light will stay on or flash continuously.


NOTE_ The best action is to clear the code, by using a diagnostic CPU. Plug the CPU into your in car port, under the dash. Follow the instruction on the CPU display to clear the code. if the engine dose not start after the code is cleared, this will indicate that there are some issues with the PCM, or PATS
