Thermostatic issues
Hi all
Hoping to get some help with the following issue. My passager side heat is not working at all, driver side is fine. I have no idea where to start. I also have the issue where when I opperate the aircon, then the centre vent stops working under throttle, but when slowing down and taking my foot off, it starts to blow through the centre again.
Many thanks

If airflow in changing with the throttle you'll need to rectify the vacuum leaks before diagnosing the heater. Start with the vacuum block in the engine bay between the 2 firewalls with the large number of vacuum fittings. check each one individually untill you know which one doen't hold vacuum then keep chasing.
