no aint tried cold air.
those o rings are a nightmere by the sounds of it dash out?
You say the hot air is working but what about the cooling side of the system (air con), have you tried to set it at the coldest setting and see if it is working?
The book symbol on mine is on but I know it is lack of gas in the air con as I found when I tried to top it up again and found the pressure dropped again overnight whereas it stayed up to pressure when I topped it up when I first got it.
... another job on the list when I finish off changing the O rings on the heater matrix.
I didn't think lack of gas caused the book symbol. Mine was totally out of gas for nearly 6 months last year & never had the dreaded symbol?
It certainly doesn't on the newer onesI didn't think lack of gas caused the book symbol. Mine was totally out of gas for nearly 6 months last year & never had the dreaded symbol?
