Hi all,

as some of you know, I've done the NL dash conversion. I've got the climate control etc etc. I thought I was very thorough during the conversion, but obviously not enough.

I finally got around to getting a mate to fill the system with gas. Push the A/C button on climate control panel, and compressor wont engage. No voltage on the blue wire. At the time, we just shorted it to get gas into the system - it took the gas, and air con blows very cold :D - So that bit is good...

Now, why won't my compressor turn on using the panel? Whats the best way to check the TX valve? Failing that, I'm assuming thermostat/thermistor? Is this the bulb inside the heaterbox?

I'm trying to remember it - I can't remember too much detail about it, or where it plug into. Is it a part of a bigger loom plug? :roll: confused atm.

Is there anything else I'm missing, as the car has the full NL climate now? Anything that could be wrong with the control panel? Any help muchly appreciated!! :mrgreen:

Does the CC unit come up with any fault codes ??

TX valve is working reasonably if the system gets cold - it is mechanical.

ECU should be engaging the A/C comp clutch - check the wiring.

Thanks Snap,

Ok, yeah it def cold - just no voltage at compressor.
So your saying if its cold when I short the compressor, that both the TX valve and Thermister are good?

I might have to check voltage at ECU...
Now to find what pin it is!! :roll:
