Hi all, I hope you can help. My 2000 S-Type V6 3.0 heating is faulty. The drivers side is continuously hot, passenger side seems ok and no cooling air con. I have replaced the climate control valve beside the radiator and replaced the heater control unit in the dashboard but it is still the same. I was going to get the air con charged but didn't see the point if it's still going to blow hot. I'm now out of ideas, please help. Regards Stuart
