Ouch at test light....lol. Not good for what we need to do.

Need to know really what the voltages are. Just because the light comes on means nothing to the way the system operates.

Let us know how hard reset did. You can get a cheap meter for about $5.00. Don't know what they cost over there, but I am sure they are cheap too.

hi with my tester i tested the wire's on the valve if i remove the plug only the red wire works if i connect the plug all 3 wire's work i get the feeling that the valve is not being told to open or close co's i got my hands on another valve and connected the plug to it with the car running and nothing happened but if i get 2 wire's from the battery and touch them to the valve 's connection's the valve opens and closes

Ok, put it on Volts DC. Ground the black lead and put red lead to center wire, should be red. With vehicle running you should have 12 Volts there. Next put red lead on Brown/Green wire. This is for drivers side. You should have 12 Volts at low temperature and 0volts at high temperature. Next the Brown/Blue for passenger side. You should have same thing. 12 Volts at low temperature, 0 volts at high temperature.
This is of course with the valve plugged in. Back probe the wires with something smaller than say a paper clip and make sure you have good connection. This will be easy on the first wire as 12 Volts you will see if you are doing it correctly.
Let me know results.

In that case, do you know how to remove the audio and climate stack?
Pull the very bottom cover out from below the radio. Pull the two side pieces from the bottom that are beside the climate panel. Now you have 4 8mm bolts exposed. Remove them and pull climate/audio unit forward. I need to look at diagram for the right pins. Use the meter back there to make sure voltage is changing. If it is not, then you need new climate control panel.
I will repost shortly with pins. This is colour specific also (the panel), you may be able to find one used from a wrecking yard. I think will need to be programmed. I cant remember.
