BMW E36 Forum

I have a 2004 745Li that has been having problems with the air conditioner. When the max button is pushed it will maybe stay on for 15 seconds and then shut down to a lower setting by its self, this will continue several times then stay on. Also I have heard a very loud sweating noise at times when the air is put on.

A sweating noise??????? is your car very nervous or hot ??? must have very good hearing to hear something sweat
Ok ok I guess you mean squeek close 2 letters are the same in the word......

Compressor and fan combination in a single unit, the air conditioning installation, air conditioning this is all noise sources. This also requires attention, you have to take into account the air-conditioning good care and regular maintenance, so that your machine continues to work in the best condition for a long time.

BMW have come with automatic air conditioning system. Driver and passenger both can set individual preferences for air temperature. There are separate air channels for front and rear seats. The central console offers a temperature-controlled stowage space.
