Australian Car Repair Issues? Ask an Auto Mechanic for Answers ASAP
I am sorry that you have not been helped yet. I just came online and saw your question.
Ok, did the A/C and central locking both fail at the same time as the audio unit, or at separate times?
And I will need the last 8 of the vin number to pull any needed schematics.
Please remember that I am not there and therefore may need to ask for more information at times
