Need Help! Turn Signal turned off but light on dash kept blinking...
 

Need help, the dashboard turn signal light on my 2004 325i kept flashing after I turned off the turn signal lever. After ~30 seconds and multiple tries moving the turn signal lever up and down the light on the dash finally turned off. However, know the turn signal lights work at the corners of the car but the lights do not flash on the dash and the turn signal clicking sound does not work.

~30 minutes later I stopped for gas and had difficulty restarting the car. It would crank easily. Outside air temp was ~92F. Eventually started after 4th attempt.

Back on the road I noticed the AC (compressor) stopped chilling the air although the blower and dash controls work fine. Also, power windows, sun roof and windshield wipers stopped working. Also, fasten seat belt light on dash remains on. I also notice the emergency light flashers work but the right/left turn signals on the dash are not lighting up in this mode either. Car starts without problem.

All fuses are fine. Central door lock button, stereo, interior lights all work find. Could this be a power relay module or ?? Thanks for the help! - Beamer T

Replacing battery and ignition switch did not fix the problem. Spoke with Scott at scott@bmwgm5.com. (Great website and Great person for GM5 issues, especially if you are in the L.A. area) Scott thought issue is with "k-bus". Thanks for your time Scott!

Will disconnect battery for 2 hours to see if system will clear/reboot as others have indicated at E46 Fanatics. If not, probably off to the dealership (s@%t). Suggestions greatly appreciated!

2hrs with battery disconected (reboot) did not fix problem. Power windows, windshield wipers, etc. still notworking and stereo is now disabled.
