I picked up a product that is supposed to help clear the musty smell out of the AC ducts. The directions say to not only spray it into the outside cabin air intake but also into the intake the blower uses when it is in recirculate mode. Does anyone know where in the cabin this is located?

 

Unusual modus operandum, as most of these products are put into the front of the car with air con set on recirc, with engine running, then you press a button on the can, close all doors, and it discharges into the car, and is then drawn into the recirc intake by the car's air con. On mine, I left it for about 3 or 4 minutes to circulate round and round.

 

It is in the foot wells, set to recirc and fan direction to dash vents only.

 

Thanks.
