My 1995 P38 only blows hot air no matter what I set the temperature to be.
Sometime ago I came across a web page with a method of diagnosing the
heating and cooling system but I can't find it now. Can someone point me in
the right direction please or give me a clue as to what is wrong?

Thanks Adam

You need to get it into a specialist with Testbook or Rovacom that can
read codes from the HEVAC. There is no way of doing it yourself.

First guess would be the outside temp sensor. They often fail (mine did),
and the CC thinks it is permanently minus fifty so it tries to warm you up.
But as others have said, a run on TestBook would be the only way of finding
out 100%.

I don't approve of signatures, so I don't have one.

Now we know who to blame for global warming :)

The heater on a series landie is more theretical than practical.
