Hi guys

Seem to have a smelly air con issue. Ran a can of the Autoglym air con sanitiser through and also changed the pollen filter, still somewhat of a smell

Bought a can that has a long flexible tube that can be sprayed to disinfect the stuff that may be built up on the air con evaporator. Any ideas how i can get to this? Instructions say to chase the tube through and spray, some say just spray it down the centre vents. Not sure what I should be doing.

Thanks
