I have a v70 XC awd 2003 model Volvo ,it is driving me crazy not finding the right thing to do .
When I drive during the day ,it seems that the heater is on at my feet ,no matter on what setting my the vents are ,there always seems to be hot air coming up from my feet.
I have had the system re- calibrated by Volvo and they also found no fault on the system.
Please some advice will be much appreciated...
Volvo says it could be the motor that drives the vents but they also say that it seems to be calibrating correct and does not give a return error..So they cannot replace if it is not faulty

Help Please !
