They all do that to different extents, I got a 2003 156 brand new and it was never much different to yours.
I found that a quick turn to 'Lo' blasts cold air behind it and cures it for an hour or so!
It gets roasted in winter by the heater, and in summer by the sun!
Mine also didnt like cold temperatures!
