No Heat

[jethead98]

Hi people, has anyone suffered from cold feet??? No heat at all from heater in my R33, any ideas....Just stopped producing. The control seems to work ok and the fan is pushing out heaps, any ideas greatly appreciated

[Guest]

try to do the airconditioning diagnostic, I think it was stop and auto similtaniuosly or something like that, someone please shed some light on this

[jethead98]

I found and run the test, but unfortunately did not show up anything, does anyone know where the water control valve is, i presume its an electric solenoid type hidden away somewhere??

Climate Control Diagnostics R32 and R33

The climate control has a diagnostic mode.

Enter the diagnostic mode by pressing the OFF button for five seconds within ten seconds of

turning the ignition on.

Sensor check

Sensor check is selected by pressing HOT switch (the red triangle) while in diagnostic mode.

The microcomputer detects whether each sensor input signal is within correct parameters. The

results are displayed on the screen.

If normal, a "20" is displayed.

If abnormal the failed sensor number is displayed. The sensor numbers are as follows:

20 - all is normal

21 - outside air sensor

22 - Inside air sensor

23 - Water temperature sensor

24 - Intake temperature sensor

25 - Sunload sensor (small sensor on the left hand side of the dashboard near the windscreen)

26 - PBR

27 - Refrigerant temperature sensor

This should tell you if any of your sensors are faulty.

Mode door position check

(This is probably not the cause of your problems but it is a nifty self check to play with).

While in Sensor check, depress the HOT button again. This will operate the the mode door

actuator, and checks the whether the position detection switch is operating. Again the results

are displayed on the display.

If normal, a "30" is displayed.

If abnormal the number of the faulty mode is displayed as follows:

30: Normal

31: VENT

32: B/L (Bi level)

34: FOOT

35: DEFROST/FOOT

36: DEFROST

You should have got error 25 (Sunload Sensor).

Word of caution, even in shade on a bright sunnny day you can get error 25.

i thought that all that did was tells the car (yeah like nightrider ) if its dark or not and turns the clock light on haha

[Guest]

I reckon that sunload sensor is useless, if it works for anyone please let me know.

no idea....he took the car on Saturday evening and returned it 2 me on Sunday afternoon.....so I had no idea what he done 2 it :confused:

[jethead98]

On the righthand side of the gearbox tunnel Adjacent to your left foot is an servo/motor mechanism that sequences the buterflies and water valve via a push/pull cable. This mechanism was stuck, gave a bit of a helping hand and away it went, all is fine now. Fault code 26 then dissapeared, left with Sunload sensor fail but who cares...Ive got heat now..

Can someone tell how to identify/find the Sunload sensor????

[Guest]

the sun load sensor is next to the windscreen vent. its the round thing that looks like a solar panel

Leon try doing the above test and see if you get an error and what number you get

[Leon.T]

k, I'll try it tomorrow morning....anyway I changed my mobile number...I'll pm u the number.
