156 blowing hot and cold!
I have a 2.0l 156 which I've noticed seems to have a problem with the heater. It had crept up slowly but I'm now certain, the problem is when it's on hot, say 24 it only blows lukewarm. It will intermittantly blow hot but most of the time set it between 20 and max and it all feels the same, lukewarm.
I've noticed the temp gauge seems to stay cooler too, used to run at around 70 going up to over 90 when stopped in traffic at which point the fans would kick in, Now it seems to sit at 65, if you stop in traffic it will eventually creep up to just over 90 but takes much longer.
Any ideas what this might be? Seems weird that the cooling would become more efficient so must be something wrong.
