Heater Blower Hot Or Cold - Nothing In-between ?

[Andy555]

Hi All,

 

Strange problem on my 2002 Alhambra TDi with Air Con and manual temperature control.

 

When the control is full anti clockwise the air is cool as expected, but if i turn it up just one or two 'clicks' the temperature instantly goes very hot.. as if I had turned the control fully clockwise.

 

So i have no control over temperature, either off or fully on.. I hope that makes sense :o

 

Anyone know if anything can be done? Clearly it's not the end of the world so I'll just live with it if it's going to be something like the matrix.

 

Thanks

Andy

Removed heater controls and everything appears to be ok there.

 

I assume there is some kind of valve that controls how much hot water from the engine gets to the heater matrix, can anyone confirm that? And also where I should look to find such a valve?

 

Cheers

Andy
