Heater/Climate Control temp

[The Tool]

Howdy all,

My heater/climate control unit does not seem to function properly. I only get cold air at 18'c or hot air at any tempertaure above 18'c.

I tried the settings with the a/c on and it made little difference (i.e. the air-con worked but still only left me with hot or cold - so settings in between).

I also tried running the diags and everything appeared normal for most of the settings. When I put it to the sensor check, where the number "5" appears, I pressed the window de-fog button (bottom right next to the recirc button), and i got a reading of between 18'c and 21'c for the first setting (which I assume is the inside air temp - seemed about right), and I got -30'c for the second (no idea what this reads).

Anyone got any ideas? It kinda sux only having a hot or a cold setting, because the climate control does not function properly....

type thing...

There's a climate control temp sensor.... It should have an electrical plug and a suction hose connected to it... make sure bith of these are connected.....

Doc.

Yeh I checked that. I only get hot on 19'c and cold on 18'c when I'm just operating the fan (i.e. with it's not in Auto mode)

A little off topic but is there anyway the climate control can display the outside temp?

there is on r32, its the AMB button.. for ambient temp i think...

IVE GOT THE SAME PROBLEM, I BELEIVE AND A FEW MECHANICS TELL ME THE AIR CON NEEDS REGASSING. NEVER HAD THE PROBLEM B4, IM GETTING MINE RE GASSED NEXT WEEK SO ILL KEEP YOU INFORMED

The air-con works, but only on 18'c. If I increase it to 19'c then I get hot air as if it's set at about 25'c or above.

Tool the calibration in the climate controll is out or the external temp sensor is faulty. the climate control thinks the out side temp is -30 so it wants 2 blow hot air to warm the car up. try resetting the climate control (same way as rebooting the ecu) i think that should work. if not then need a new external temp sensor.

hope this helps

I've got the same problem..... where would I find the external temp. sensor??? :confused:

I'm guessing it's somewhere at the front of the car since thats where all the damage from 'the accident' happended, and before that it was all working

You'll find the external temp-sensor just under the horn.

At the very front of the car (in the middle).

It's black and is about 3-4 cm's long...

Hope that helps. (I had to re-locate mine as I installed an FMIC).

Cheers

Tried the ol' ECU reset but to no avail. Will be having it looked at this weekend. Wanna make sure I have climate control for a long drive to Byron for NYE!!!

Mine had exactly this problem. A plug had come off at the back of the control facia. Plugged it back in - all good

I know this is a very old thread, but I am having the exact same problems as described here.

Cold air on 18'C, hot air on 19'C and above.

Diagnostics saying that one of the temp sensors thinks its -30'C

So did anyone find a solution to this?

The external temp sensor on my r32 was on the frontbar just behind the number plate.

it's a black little like box, with a metal bracket on it, and a bit of wire.

mayb unplug it, clean it out, u may need to replace. Not sure how it works,

i think the sensor is an active sensor, so it might work from a voltage return.

or it might work by resistive.

I know when i diconected mine to see what would hapen it showed -30'C.

So check the wiring on the plug, move it about....

u may need a new sensor, or your wires shaged or mayb where ever it goes into is disconected or shaged.

Good luck.

Madtrang,

I had a look and was able to find the sensor.

I am little curious as to how you disconnect it. Mind you I was using a blue led light in a car park (really hard to see but better then nothing), as I couldnt find a torch.

It had a cable coming out one side with tubing around it, and the otherside had the bracket connected to it.

So if you could give me any help with disconnecting/reconnecting it that would be fantastic!
