Opening a heater flap actuator, Mercedes Sprinter 2019

This video is specifically for Andrew Taking apart a Heater Flap Actuator from a Mercedes Sprinter 2019 and comparing the difference to another from a Mercedes A class 2019. Spot the difference? There is only one lesson to be learnt by watching this video; that is to take your time, don’t go nuts and break all the tangs that hold it together just because you are impatient. It can be done! Firstly: There appears no way that you can test run these units to prove if they are good or bad. Secondly: It is therefore pointless taking them apart. Info. - For Nerds Only! Although not relevant to the chip within these actuators https://ww1.microchip.com/downloads/e... Link to data about Atmel ATA6641/2 is an interesting read, especially about LIN slave addressing (page 5 of pdf). Article seems to date from 2011. As with a lot of these Automotive IC’s, they are tailored to vehicle manufacture’s requirements to order. Those I have found suitable for LIN bus / H-Bridge applications and still in production are not available off the shelve! How tiresome? 00:00 Intro 03:30 It's a Stepper Motor! 04:46 Pin Connections. 06:53 Tools Required. 12:10 Gear Comparison. 13:55 I.C. Part Numbers. 16:32 Another anomaly. 17:40 What I had intended. 18:28 Lesson to be learnt. Link to early video but no point watching.    • Mercedes Heater Door Actuator
