190 heater giving cold air

[zulu]

I have recently purchased my brothers 190 and the heater is giving cold air only. Brother said that he had it checked and was told that the matrix is causing the problem, but is an annoying job by removing dash etc.

Can anyone please tell me if there an easy way out, as I froze my balls off whilst driving from Southwest to London during the cold spell.

How can I get the heater to give warm air?

The easiest thing to check is the Heater Control Valve which is located next to the wiper mechanism under the bonnet. Its a little in-line valve that switches on/off the flow of hot water to the heater. It is controlled bya pneumatic hose. As I remember, the default position is 'heater on' but I guess it could have jammed or be caught on something. - Easy to check anyway B4 you take the dash off!

BUMP! My 190 is giving out only warm air NOT hot air even on max. I checked the valve mentioned above. I took off the red vacume line which runs through the bulkhead into the car and I pushed the arm on the valve upwards then put my finger over the vac inlet and it stayed up. The default postion seems to be down (ie about horizontal). Can anyone tell me if the valve working okay or is it dead? Also should the valve "leg" move up/down when the heater controls are turned from cold to hot?
