Drivers Side Temp. Control Not Working...

[AMG ETR]

Hi Guys,
So we finally had a chilly day here in S. FL and i tried to use my heat and to my surprise the air never warmed up no matter what I did. What I noticed the next day when I looked into it a bit was that the passenger side works fine, but when I adjust the temp. dial on the drivers side it has no effect whatsoever. I have the manual A/C (no screen). Any ideas?
Thanks,
Evan

Have to take it to he dealer. I had that happen to mine when I first got it. I think it was either a sensor or something that they need to replace or fix.

It is your mode actuator that allows the warm air to flow to the driver's side. It is a common issue with these and other makes and models. If it is under warranty then it should be covered.

Not under warranty, is there somehwere I can read about this and fix it? I have open access to a shop full of tools and I am very mechanically inclined...

I had the dash apart not too long ago and don't remember if it was after that when this started, but maybe I forgot to plug something back in? Where is this sensor/actuator, I'd like to make sure i plugged it back in...
Thanks,
Evan
