Evening all. The issue i'm having on my 2010 fr170 is the heater isn't getting as hot as it used too. I say that for the drivers side as the passenger side gets hot but unless you mess with the different heater positions the drivers side just blows cool/warm. If i switch between face/feet/screen etc and even off then on it can kind of reset itself if you get me and blow as hot as the passenger side. I don't use it on the dual function so both temp dials always move together. No damp patches inside the car. I had my front screen replaced about 6 weeks ago but like i say there's no damp in the car so i presume its sealed correctly and not caused this. I have noticed that my windows do get dirty real quick inside lately but i think the pollen/cabin filter is due for replacement. Could the filter have any effect on the heater though? Apologies for the essay and thanks for reading. Dave.
