hi all,
i wonder if someone could help. i do not understand my heating system.
if i'm driving during the day and i put the heating on to 21.5 degrees, i get warm air through the vents. this is a good thing. when heating has been off for a while, and you put the heating back on to 21.5 it blows cool tepid air, not freezing air. so i touch it up to 22 degrees. same thing cool tepid air. for example. today i drove to hastings from london. in the morning after the car has been running for 20 mins, i put heating on at 21.5 as mentioned above. i turned it off once sun was shining through car and we felt comfortable. all ok. now 8 hours later after our day out, we are driving back to london. we feel chilly and put the heating on 21.5 degrees. it blows out tepid cool air. i left this on for over 20 mins. so i touch it up to 22.0 same thing. i again touch it up to 22.5 no joy. when i put it up to 24-25.0 warm hot air blows through. my question is: is this normal? in my old gs300 i can leave it on 20.0 degrees, and its warm air. its only on mega cold days it goes up. so it seems that during the day its ok, and in the evening its not, or is this coincidence? i'd like to hear from other drivers if this happens to them. what is the temp borderline where warm air kicks in? by the way, i don't use climate control, im manually adjusting the climate for example:
press climate
choose fan speed
turn off "a/c" (bottom left)
and adjust temp myself
many thanks
