Thanks, they give me some avenues of attack.
Incidentally I have emptied 3/4 of a can of Glen 20 already both inside the cab with ac on recirc and also from outside into the inlet vent. Made a huge difference to the smelll, reducing it considerably. (Previous owner was a big smoker). But I would like to try and clean the Ac evaporator . There’s got to be a lot of crud in there.
