What is that terrible musty/mold smell coming from my air vents? There have been numerous complaints of a bad musty/mold smell coming from the air conditioning vents. This usually occurs after the A/C has been running or after the truck has been sitting.
This smell might mean that your coolant is leaking from somewhere like a radiator or heater hose. This kind of a problem means it's a good idea to take your car into a professional. If you smell maple syrup outside the car, this might mean that you have a leaking radiator cap or that the radiator itself has a leak.
