Ok, I have again had the loss of heat into the cabin today however this time with the fans locked on almost full. I pulled over and reset fans which appeared to work, however it was the same again after being parked up.
I reset them again and drove about 10 miles and it was ok, but as I clicked throught the trip computer I noticed the outside temp was blank. I tried to reset this and it was still blank. After stopping for fuel it remained the same. Could this be related???
Why do my cabin heater keep blowing cold but is easy to reset???
Any clues anyone?

I have heard the AC doesn't kick in below a certain external temperature so that seems to link the external sensor and operation of CC somehow. I could be wrong though.
If the extenral temp sensor is knackered, it therefore might interfere with the otherwise correct operation of the cabin temperature controls.
Need someone to confirm thought but I can see a reasonably deduced link between the two.

The two are separate on PREface lift cars, but the outside sensor does have a bearing on cabin temp on facelift cars. :y

well mine is a 99 with full electric climate!

Ok, so what would cause the interior climate control to go daft then??
-
Ok, well after a couple of days of driving Ive come to the conclusion that my interior climate is affected by the exterior temp sensor because when the ex sensor dont work the interior goes scatty and when it does work the interior is fine. So looks like I need a new exterior sensor. ::)

I have a 2001 "Y" 2.2 CD and I am having problems post the snow with my heating. System flushed OK and get heat sometimes but other times only cold.
Where exactly is the outside temp sensor located? I have heard "somewhere near the nearside fog light" but that kind of sounds like a guess and not someone who could actually point to it!!

Yours is a facelift car, so it's right in the middle of the bumper quite obvious when you open your bonnet & look down.
The "somewhere near the nearside fog light" would be obvious too if you had a PREfacelift car ..... it would be the only thing fastened to your bumper in that vicinity. :y
I can't point to it ..... I'm not there! ;) ;)

Many thanks!! This afternoons jobs marked out then.

I'm sure you manage to squeeze another job in. ::) It'll only take you a few minutes to chnage the temp sensor. ;D ;D ;D

Facelift, yes. Pre-facelift, passenger side behind bumper

No wonder I couldnt find it then. Does the bumber have to be removed or is it accesable without??

I said ... look down! ;) ;) ;) Later cars still have the sensor attched to the bumper, but it's in the middle, not at the side like on a earlier car. :y :y
Bumper can stay put! ;)

I did look down but couldnt see it. I could see the large air hose and the two fans. I could also see a number of pipes but nothing that looked like the sensor I bought. ::)
Will have to have another look tomorrow :-/

I'll have a look tomorrow for where the other end of the loom comes from.

Mine was mounted to the lowest part of the bumper 'looiking down' onto the road.

Found mine on facelift 2001 2.2 CD. If you look down you will see where you fill the wash bottle up. To the left of the filler tube is a black elongated tank which holds the wash water and which has TWO separate electric units attached. One is the washer water pump and the other is appears to be the heater for the washer water. If you reach down underneath the washer tank you will feel a small round unit with two leads. If you lever it gently away from you it will pop out of its hole, and that is the exterior temp sensor. If you unplug the sensor from the cable, your dash display for exterior temp will just show a couple of dashes. Plug it back in and it should change the display to a temperature reading. No reading means the unit needs replacing. About £5 I am told.
