First, sorry about the test thread I added earlier. It was meant to be sent to alt.test... However, in my volvo 245 -80, I experience that the air flow from the heater is bad. Hot air comes from the outlets, alright, but not many liters per minute. Is this just the old Volvos having a bad flow from through the heater or could it be anything else, such as obstructed air intakes (how to clean btw)? Any tips are appreciated! Anders
