P38 Climate control diagnosis

May 26, 2006 4 Replies

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%.

Now we know who to blame for global warming :)

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