My aunts 2016 C4 Picasso has dual zone climate control. However it only heats up on the passenger side.
I have removed dash panels and looked at the flaps, they seem to be moving smoothly and reacting to the controls on the screen. But no heat comes from any vents on the drivers side. It isn't even slightly warm on the drivers side its very cold.
I have pointed a thermal camera at the matrix on the passenger side it is sitting at 60° on the passenger side albeit through the plastic of the heater box it is sitting at 22°
Has anyone had issues with the matrix clogging up to the point where one side is completely cold? I suspect i need a new matrix but trying to think if anything else could be the problem.

Very common problem, needs a new matrix. Fortunately easy to do as it's accessible from the passenger foot well.
