Z3M problem...

[Z3Mroadster]

Hello!

Problem 1:

When I lock my car blinkers don't blink as before...
They work only in one of 20 attempts

What is the potential problem?

Problem 2:

Air conditioning is switched off but the fan itself starts working and switch off.. So again...again
....

Thanks in advance

Not sure on the alarm issue, other than the module is behind the passenger glove box. Mine had a fan that ran all the time cooling the ECU could it be that or is it really loud?

Sounds like the air conditioning fan is connected to the radiator switch.
This has been done on many cars so the fan cools the temperature automaticly.

I don't know about the alarm.

I think the alarm module has a relay for the indicators so I would hazard a guess and say the relay contacts are fubarred. I think the hazard warning uses a different relay but just check when you put your hazards on they are flashing ok as they might be linked.

The fan could be something to do with the thermostat switch as the aircon fan does cut in when ambient temps are very high in the height of summer to provide additional cooling. The thermostat switch is located on the left hand side of the radiator at the top so check that out.

Working the front fan and not from ECU...

When I turn off the switch on top of the radiator,then the fan is switched off....

Where are the relays?

I have replied to your PM's but would be helpful if you could post a picture or two of this switch so we can have a look. Just click on upload a file button below and select and image and it will post it in this thread.
