R32 Heater Problems (climate Control)

[lows_13]

The other night if was cold as so i went to put the climate control on, turned up

the temp to 32 degress and waited for hot air to come out, waited, waited, nothing,

the only thing coming out was cold air. I was using the heater a couple of nights before

and it seemed to be working fine. Everything else work fine as far as i'm aware of,

has anyone incurred this problem before?

Run a diagnostic check on the climate control system. The Workshop manual explains how to. If you dont already have it search for it and d\l it. It sounds to me that the tap that controls flow of water to the heater is not opening. It could be stuck or just plain broken.

Where is this valve located?

Is it switched over to blow on the windscreen/feet?

I don't think it's supposed to blow hot air in your face.

i have the same problem just cold air comes out

[lows_13]

Yesterday it all seemed to work ok,

the only other thing is the AMB air temp button read

20 deg the other night and it was freezing cold. Today it said 13 deg and it wasn't all that cold.

In my r32 it seems to heat/cool according to the ambient temp. below 18C ambient and it will heat even with the A/C on. I suspect your ambient sensor is playing up.

I reckon mines got the same issue as yours.

Is it as simple as changing the Ambient air temp sensor?

I don't think the ambient air temp does too much.... it just tells you how high the temp is *outside* the car, and maybe does a small correction..

Proper way to test it all is.. put key in ignition position..

within 10 seconds, hold down the "off" button for 5 seconds.. will go into testing mode..

Press "up" (the arrow) 5 times i think it is (or is it 4).. this goes into the temp sensor area (it will display the temperature of each sensor in turn - there is about 4). Press AMB to view the temp each one is reading in turn. If you've got an abnormal or -30deg in any of them the sensor is bung.

There are other tests you can do when in the testing mode, but I think think the above will be most useful in this situation

[HR-32]

There is a sensor at the front of the car (ambient read out) and there is another to the right of your ashtray behind the 4 little slits, I think, but not sure, your A/C and heater works from the temp coming from there and heats or cools accordingly. Can anyone else confirm this?

[predator]

yup.. thats the inside air temp sensor.. that's the main one.

p.s. if anybody has a spare one off a halfcut or whatever, I need one

When mine was doing this, it was the actuator arm falling off the blender motor (I think that's what it's called - that's what we called them when I worked for Ford anyway). The bit that controls whether hot or cold air came out anyway. It was stuck in the "cold" position obviously. I didn't fix it, but my mechanic had a quick look under the dash for me when I was there for something else and he fixed it in half a minute with a circlip or the like.

try with econ on and econ off, and not with a/c selected, then if that doesnt help (im sure you would have already tried that) try hold the temperature UP button for 5 seconds, activate the fast heat mode and see if that is hot.
