Turning signals, Ac and sound not working
I have had my 2004 z4 3.0i for about half year already and just got my first issues.
My turning signal on the outside work but dash doesn't show it. AC is working periodically. Sound does not work and so does the rest of the radio. I have looked at some forms they say it is the Airbag control module. Not sure if it is the same issue please give some help. |

Amp issue could be that you’re “blown” the amp due to water issue.
I have the same year /model… the amp is in the trunk under the “floor mat” in a well next to the battery. Water intrusion into the trunk will collect and short out/damage amp components… Other issue could be caused by low voltage issue. Check your battery cables for corrosion. Check battery voltage when cold…. Start engine and read voltage… check voltage regulator output. Buy yourself a plug in voltage reader that plugs into the “cigarette” lighter power outlet on the center console. It’s the easiest way to do the above. Google.. “ Z4 low voltage issues” … “car battery voltage for expected battery voltages. Google is your friend…
