My 54 plated cars  climate control is blowing hot air on the passengers side but working normally on the drivers side. can anyone help with the probable cause?

Did you find your answer on this one?

If anyone has an answer to this one, it might help my dad. He has a Saab 9-5 (Y reg) that had the same, but was told it would cost him £500 in stripping out the fascia before any fault could be identified. As it happens, it seems to have righted itself since but if the problem recurs ....

Hi

I think I may be able to help. The problem is probably with the connector that fits into the the heater control module, because of its position down the side of the radiator it is prone to corrosion and eventual failure, I have just had my 2005 S Type 2.7D cured of this problem, the connector wires if badly corroded or broken will give these symptoms, its what I experienced. A replacement connector can be obtained by using the brake master cylinder connector of a  scrap Ford Focus readily available & not in a position to be corroded, I had the new connector wires soldered on to the three wires after removing the connector from the harness wires on the Jag., result wonderful cold air on both sides of the system also hot as well if you require it
