Classic sign of low gas, cold one side, hot the other, I guess you have a minor leak which is taking a long time to all leak out....  Pete

That pressure is a fraction on the low side, at an ambient of around 17C you should be around 950-1000kPa with the compressor running. However, its not too low that you should have temperature differential across the front. That is usually indicative of a failed blend door motor. That is quite a common issue and usually it is the drivers side that goes first, being the one that gets most use. It's not a massively hard job to change the actuators yourself.

If you have a decent scan tool it'll give you the blend door actuator position from the AC module readout. If changing the temperature dial doesn't change the door position then you know that is your issue.

Thanks for this bit of guidance really appreciate it. Range Rover Vogue SE 4.4 SDV8 SVO Stying Pack
