Having trouble with the heater air flow of my 1998 K11 Micra and having read the threads on here now suspect a blocked pollen filter as I have done the following,took the hoses of the heater matrix and back flushed it,checked the on off valve which is ok,put in a new thermostat,checked that the water was circulationing through the system and heater it is,checked all control cables are operating they are and feel right,reading the threads here I seen the pollen filter mentioned and thought if that's blocked it could be the cause of the no air flow,the Haynes does not mention the pollen filter and I did not see it in the car but was not looking for it as I did not know it had one,can anyone help,looked at the Mann filter site and it lists one from Feb 1998 on,any help would be greatly appreciated,thanks in advance.
