HVAC problems

Recommended Posts

I found this when searching...

For those of you who's with the E36ers and would like to know the what the HVAC codes are, check this out:

HVAC Hidden Test Functions (Climate Control) - E36

--------------------------------------------------------------------------------

The HVAC (Heating, Ventilation, Air Conditioning System) of the 1996 E36 has

a feature allowing different sensor values to be displayed on the control panel.

To Access the Display Function:

Press the "AUTO" and "REAR DEFROST" buttons simultaneously.

12 displays are available.

Toggle through them by pressing the fan rocker (+ or -) switch.

Number

Test Function

1 Interior Temp Sensor

2 Exterior Temp Sensor

3 Left Heater Core Sensor

4 Right Heater Core Sensor

5 Evaporator Temp Sensor

6 Engine Speed Input

7 Road Speed Input

8 "Y" Factor Value

9 Fresh Air Flap Position (%)

10 AUC Sensor Voltage

11 Battery Voltage

12 Software Version

To Exit the Display Function:

Press the "RECIRC" and "AUTO" buttons simultaneously, or

Turn off the Ignition.

Note:

1. Decimal Points are not shown, Hence 75.5% is displayed as 755.

2. All Temperature displays are in ?C (Centigrade).

3. Negative values are indicated with minus sign

Does this apply to the E39's as well? I am having problems with my HVAC. I don't get cold air, warm air or hot air. It was raining lastnight and I couldn't get windscreen de-misted. Any help will be GREATLY appreciated.
