Join us for a great Tech Talk video-teleconference (VTC) on Saturday, January 22nd at 11 am (Eastern Standard Time) when MBCA National Technical Advisor George Murphy will present “R107 Climate Control/HVAC Systems”. The newest R107s are 32 years old and and there are a number of varients of the heating, ventilation and aircondition (HVAC) system. They can each be challenging to diagnose and repair. The plastic servo in the second generation system is also prone to cracking. George will cover the basic operation of the various systems, diagnosis, and repair. Following his presentation, we have plenty of time for questions and answers on this, or any other Mercedes topic.

Peachtree Section President Gary Edwards will act as host and moderator. Edwards points out that questions will be solicited during the VTC via chat. Edwards comments, “The feedback from our technical sessions shows a big appetite for technical information. This event is designed to fulfill that desire, and though we've covered typical maintenance of R107s we haven't covered the different varieties of their HVAC systems. This is an area that George specilizes in, and his company Performance Analysis provides improved versions of some of the impossible to find HVAC components. The question and answer session afterwards will be open to questions on any Mercedes topic. We are especially fortunate to have the club’s technical advisor George Murphy as our presenter; you won’t want to miss it!”

He has been a member since 1978, was a charter member and President of Smoky Mountain Section and has served as a Director at Large and as National Treasurer.
