Smelly Aircon

Post by JAMIE170 »

The warmer weather has exposed a new issue with my car - I've got the common musty/mouldy smell when I turn the aircon on (since buying the car in Jan/Feb I've had it on auto without the a/c on, probably my first mistake). I'll be changing the cabin filter as it's cheap, easy to do and just makes sense.

Can I do any harm by running the fan/aircon without the filter in place?

My thinking is if I remove the filter and turn on the aircon, if the smell is gone, all sorted, I'll just fit the new filter. If the smell persists then something else is responsible and I haven't contaminated the new filter.

My next step would be to use one of the aircon cleaning 'bombs' , would this be more successful used while the filter is removed?

Any thoughts/ideas/suggestions appreciated!
