Here in the US, the Sprinter comes standard with what Mercedes calls Tempmatic AC control (HH9) where the fan speed and air distribution needs to be adjusted by the driver.
In this video, I am going to upgrade to Thermotronic (HH4) which is a fully automatic AC control where the van automatically adjusts fan speed and air distribution to achieve the set temperature.
for this upgrade I am using a kit from KUFATEC which comes with all the necessary parts.
I do have one of these kits for sale. Please follow this link for more info:
