Product Details

Only the heating system is covered in this two part video series. Air conditioning issues and troubleshooting are not covered. Using a 1979 W116 300SD and a 1980 300TD wagon Kent will walk you through the basics of the system and how it works. Troubleshooting and repair of the system will be covered in Part 2.

The specifics covered in Part 1 are:

  • How to recognize if you have this automatic climate control system
  • Where the key components are located
  • What each one is called
  • Differences in mounting the switch panel in the W123 and W116
  • Overview of removing the switch panel ( not detailed )
  • Details on getting to the servo amplifier
  • Removing the glove box liner
  • W116 and W107 Servo location
  • W123 servo location
  • Wires and hoses to inspect
  • Function of each key component explained up close on the bench
  • Importance of a healthy vacuum system - this is key!
  • Temperature sensor issues
  • Conclusion
  • What will be covered in part 2.

PLEASE NOTE WHAT IS NOT COVERED: This is NOT an advanced diagnostic video for the hardcore mechanic. Kent does not expect you to open up and repair some of these components so this is not covered. Advanced electoral and vacuum system troubleshooting is not covered. Also, step by step instructions on removing the switch panel and the servo is not included. Only general information is covered along with challenges to inspect. Servos are straightforward and easy to remove. You just have to remove a lot of hoses and wires. The switch panel is more difficult to remove in the W123 because you have to remove the center console piece over the trans tunnel (between the seats)
