First, isn't this a known issue that involves the diverter baffle??? Are you sure that isn't what you're seeing?The rotary knob controlling the vents started acting up within the last several years and wouldn’t activate the defroster. Now it won’t activate any vent other than the dash vents. What’s the latest news on repair or replacement?
Thanks. I hope that isn’t the problem.We've not seen a control actually fail - much more common is the motors that move the blend doors - there are three and they are deeply buried in behind the cross car beam which means access is a major task.
The heater box that they're mounted on is one of the first parts put into the body during build so you have to remove a ton of stuff to get to them. Motors themselves are not expensive.
We do use a camera probe to check the fault here - unfortunately that's the easy bit..What I mentioned as baffles == blend doors. Based on history it's most likely the problem. I'm surprised noone has managed come up with a means to snake a camera prob to confirm with disassembling the dash.
I'd like to talk with him about any "secrets" or a path to trouble-shoot/fix an in-op/sticking mix door.I have someone down here (a former GT owner) who handles the sticky blend door issue. He has done several for me and has only ran into one car the will require HVAC assembly removal. Just a reminder, every time you drive your 05/06 GT, take a few seconds to run the HVAC blend controls through a cycle. (floor to defrost) Especially important in our beautiful western / southern heat.
