Clima heating problem
« on: 29 December 2019, 21:54:18 »
I have a problem with the heat of the clima. In my case sometimes hotter air comes out than others but never as it should, can it be a problem with the heta valve? Or some weather engine? I have passed the Op Com but I don't know very well how to check.
Thanks

Have you tried resetting the servos for the air distribution? From the owners manual:

"If the electronic air conditioning system is not functioning in the usual manner:
press the AUTO and OFF buttons simultaneously for approx. 5 seconds. The servomotors will
be synchronized, during which time the fan will temporarily switch off."

I take it your heater fan is working properly and there is hot air sometimes?

Thanks! I will try it. I don´t have the owners manual. The fan works fine, it's the temperature that doesn't always come out hot

Blocked heater matrix.


You could try flushing it, but a new one would be a proper solution.


Cheap part, horrible job, but worth doing.

Do you believe? The question is that sometimes it comes out hot ( not too hot) and sometimes it is warm.

The thermostate is new and work fine.  I reset the clima and it's still the same, everything points to the matrix. Because the heat valve is there any way to check it? With the op com always apear closed

The heat control is a diverter flap in the airways. The matrix is a dumb unit with four screws and two hoses holding it in place. Nothing for the computer to see ;)

  This ^^^^^^^.  Most matrix are over 15years old now, so a blocked one is common,, about £20 from eBay, and make sure it has the o-rings,,

 I cleaned the refigeration circuit with a liqui moly product and it works again! In effect the problem was the matrix but it seems that at the moment it is not necessary
Thanks to everyone!

Give it a week ;)

Sometimes the only effective solution is to replace parts...

Yes, of course, but now I'm 100% sure that the problem is the matrix and not the temperature control engines that was my doubt.
