There should be a drain tube poking out of the bottom of the Firewall. Make sure it is not blocked.

There are some products for cleaning the ductwork and eliminating mold. For this, Ford makes a product to spray into the ducts. There are aftermarket products but many retailers have pulled A/C products from shelves as Winter approaches.

A company called Servall is an appliance supply chain and they have stuff for using on Refrigerators and Central A/C units. The main thing is whether it is safe to breathe so read the instructions before occupying the vehicle.

    Im pretty sure you have an interior air filter, much like the air filter for the engine, the interior or body air filter needs to be changed as well. If it is old and moldy, that may be your source. With a good mask (so you dont inhale all that nastiness) you can clean out the air intake area with bleach and water. I have also seen vehicles with a lot of leaves and dirt build up on the cowl screens (under the windshield). They also need to be clean or you can get that musty, mold smell inside. Just some extra thoughts, good luck!

Mercury marnier won't start

Yes, you can jump start this hybrid. Connect cables the same as a non hybrid. something was probably left on and killed the battery. Make sure the battery cables are tight on the battery.

Musty smell from A/C in 2001 Pontiac Grand Prix GT SE

Most common cause is water sitting in the bottom of the a/c heater box. Make sure the outside drain is open. There are spray products for using on the vents.

The heater has a musty smell,I suspect i need to

It sounds to me if you are having a "musty smell" then you might have a problem with your condensation drain line for you a/c system or a small leak on your heater core. If it is plugged then water will collect in the vent system causing a musty smell from the water not draining and if there is a small leak on the heater core then coolant can collect in the vent system. I would run the a/c on a warm day and look for water draining from the vehicle around where the dash is located to check the drain line. As far as your air cabin filter most are located behind the glove box. You usually need to remove the glove box to get to the filter.

Strange smell coming from my crhysler crossfire air con. intermittently musty smell from start up and while driving - seems to be at lower speeds. please help if possible

Firstly change your cabin filter(s) if smell still present then there is a cannistor you can buy from AC speciallists. You open the canistor, leave in footwell, close the car (windows, sunroof etc) and leave for a few hours. The can lets off a special gas that kills bacteria caused by AC. Problem solved.

My 2005 cobalt has water leaking at the heater core cover but it is clean water and only leaks when it rains or i wash it

I have not had one person that is happy with the cobalt. Everyone I have known that has one has traded it in before all the other problems occured. . You will have to test areas with water and see if it causes a leak. Also the box has a vent hose that could become clogged. This will also cause the AC condensation to overflow. Run the AC for awhile and see if you get drainage.. If not its clogged

There's no cabin air filter on your vehicle. What happens is dust, lint or so-on gets trapped in the evaporator core for the a/c and starts to stink over time. Ask your local parts store for a de-oderizor spray for your a/c.
