[ChrisWoolfenden]

hi, my cold air blasts out on fan setting 2-3 but if i slide it over to hot it hardly feels like any airs coming thou plus its not very hot either, any ideas anyone, rep awaiting

[ChrisWoolfenden]

it cant be fan coz cold bursts out, and heater matrix dont affect air flow does it?

Pollen filter is most likely blocked mate. Either that or your heater matrix has packed up

Check in order

Air block
Thermostat
Temp Sensor
