I remember get my previous E36 air-con repair in jb workshop near the famous ta ma market. Repalce a leaking cooling coil plus labour cost less then Reggit$$500 plus 1 year warranty for the new coil. I think for coe car get it repair in jb is much more cheaper. This workshop repair all type of continent car air-con.
I have this strange symptom/ fault on my E36 320i year 1991 with regards to Aircon mal-function.
Aircon blower is turned-on - there is no (green) light on the Snowflake, Re-circulation push-button and also no light on Rear screen Heater push button. There is lesser airflow than normal.
No cold air coming from vents ie compressor is not engaged.
The problem is intermitant – sometimes (50% of start-up) it works fine.
The fault normally occurs in the morning, but after a short drive of about 30 to 45 mins – I switched the ignition OFF and ON again – the fault just disappear and both green lights on the push-button are lit. In subsequent re-Start – it is all back to normal ie the aircon is functioning with green lights turned-On on both push button.
In the evening (ie after the car is left in the hot) – the air-con works fine upon starting.
I have ruled out the following:-
• Low Gas level – this can’t be the root-cause, since the problem is intermittent. There are occasion when there is green light on the push –button, there is cold air coming out from vents.
• Relays – I have replaced the Compressor relay and the Aux Fan Relay
The fault remains.
• A workshop recommended me to change all the fuses on Aircon in the Fuse Box. After changing the fuses – the problem remains.
For those who have accounted the same fault/ symptoms – kindly provide your advice you have had the same experience.
get ur aircon circuit board checked. sounds like the exact same thing that happened to mine. fans work but nothing else works, all the lights not coming on.
Was systematically (and extremely patiently) traced down by Rodney@R2D to a capacitor on the circuit board.
Thanks for the valuable feedback. The trace tends to direct towards the climate control unit or even the capacitor, the evaporator temp sensor might be faulty giving too early signal to the climate control unit or there could be a control setting which need to be reset.
I really tresure this bimmer machine although just got it within a few months - it has got a powerful engine n smooth, no other problems, other than the one described above.
Appreciate other feedback from other bimmer owners, if there is one.
