'98 2 litre petrol.

Heat only comes through when on max, anything below that is cold air - any thoughts on the problem?

[skyblue]

Have q look at maintance guide and see if the matric flush would help  sort the problem  :-/

[Boditza]

or the HBV(heater bypass valve) if the car has one.. we'll w8 for someone to confirm

[kingers]

Ya read the maintanence section before posting - no mention of this type of problem.

[kingers]

anybody got any suggestions?

[Jimbob]

When you say Max - is that Max Heat or Max Airflow or Both?

Have you flushed your heater matrix as suggested??  Always a good starting point for low heat.

And what is the temp of the car?  sitting at about midpoint on the guage?

[Neil_MV6]

This happened to me when the outside air temp sensor had failed. New one acquired for a couple of quid off ebay and problem solved.

[kingers]

ah now that makes sense- the on board computer is reading huge temperatures.

Where is it located and is there anything I can do to fix it or do you have a link to where you bought yours?

I was referring to max temperature

[RobG]

Temp sensor lives under passenger side of front bumper, about £6-7 from VX

[kingers]

thanks - will take a look and see if the connections are ok first

[kingers]

trying find it - what does it look like?  is it inbetween the washer bottle and rad or lower down by the horns?

[Roger777]

Hi just in front of nearside wheel on bott of bumper 14mm hole,but check 2 wires running back to harness,1 of mine had broke only thin wire

[kingers]

thanks roger - must oil change her during the week so will get it up on the ramp and a take a proper look

[kingers]

think i found it - dangling be the wires by the horns - is it a small black (like the size of a 50p coin) with a push in locator at one end and an electrical connector at the other end?

It was a bit corroded so we cleaned up the connectors which worked for a while but it was gone crazy again this evening - will probably just replace it.

Where does it locate into though - couldn't find a home for it...

Just experienced the same problem, heater is only blowing hot at Hi setting, the external temp. sensor not showing on dash. I have found a used sensor in the garage but.............

I cannot find the sensor on the car  , the only wiring in front of the passenger wheel at the horn are for the horn and fog lamps.

Have they relocated the sensor on the later model ?


FOUND IT......  on the later models it is in the middle of the bumper, below the washer bottle.

All working well.
