Hi John
Good move cleaning out what you have so far. There are few other things to check aswell. Can you hear the motor running for the air intake?. Does the blower control feel positive as these can get jammed aswell?
Most common that gets missed and on services too is that under the front wiper pannel tucked away (middle towards firewall if I remember rightly) there is a polen filter to remove dust etc before the air enters the car. They are made of paper very similar to the engine air filter. If not changed (many people dont change them on service as they can be hard work) they go hard and then its very hard for air to penetrate the filter and enter the car. Hope that helps you a little
regards
