We noticed a musty/moldy odor coming thru the air ducts of the vehicle during 2 recent long trips. It doesn't seem to matter if its air conditoning or heat. We think its made us sick (cold like symptoms). It is otherwise a very reliable vehicle. Is there a way of cleaning out the air circulation system in a vehicle like this removing mold etc?

Thanks

if you have a cabin air filter change that, also take out the blower motor and spray bleach water into the duct put the blower in and turn it on and let it circulate, keep repeating this till no more smell.
