bad smell when the ac gets turned on

[Rsanchez184]

i have a 04 c5 4.2 when i turn the ac on
a bad smell comes out for the first couple of seconds (maybe 10-15)
i do smoke...BAD...i know how can i fix that
i do have air fresheners and i also have ozium but nothing seems to change that

Always check the following; a/c condensate pan and condensate drain pipe smells and odours, for ac odours use 1z Klima-Cleaner Air Conditioning Cleaner or Wurth A/C & Heating System Cleaner, an effective means for removing odour-causing bacteria, smoke fumes, fungi and other germs.

Tip- turn off the AC but leave the fan running for the last minute or two before turning off the ignition to help dry the condenser and surrounding area.

You want to spray it into the intake where the cabin filter is while you have the air on. This way it gets sucked in through the whole system.

Not necessarily. You use he ~2ft tube provided and feed it down your center vent to reach the evaporator. (This is where the source of odor-causing bacteria resides.)

Spray a considerable amount and let it sit for about 20 min. Next roll down the windows and turn the AC on high for 1 minute.

Done.

Application

• Turn off ignition, air conditioning and fan system and adjust fan position to recirculation and make sure it is NOT on the 'foot' or 'defrost' position.
• Shake can well for one minute to ensure proper foaming of product when dispensed.
• Attach the supplied spray tube to aerosol can and insert end of tube into centre (as this is the closest the evaporator core) air conditioner vent located on the dash in the cockpit interior.
• With tube fully inserted in vent, press trigger to dispense contents.
• DO NOT invert can when dispensing. As you spray, the thick foam solution will travel through the air vents towards the evaporator (the source of odour causing elements).
• After dispensing product, wait 20 minutes for product to clean the system. Then, open doors to allow fresh air to enter vehicle.
• After about 30 minutes, you’ll smell a fresh, citrus scent throughout the passenger cabin. The scent only lasts for about 12 hours, but the air will be free of odours for months

Options:

1: Apply Klima-Cleaner tube through the evacuation/drain tube of the evaporator core located underneath the vehicle. Option

2: Remove blower and insert tube through main ducting of housing.

Another significant benefit is the result of cleaner interior air. This is especially important for allergy sufferers who are sensitive to airborne contaminants. For those who are highly sensitive to chemicals, rest assured that Klima-Cleaner is a water- and salt-based cleaner so chances of any skin reaction is extremely minimal.

Tips

1. Turn off the AC but leave the fan running for the last minute or two before turning off the ignition to help dry the condenser and surrounding area. Change cabin air filter

2. Turn on fan to maximum setting with A/C setting in ON for approximately 1 minute to dry system. as a result of improper application

3. Change out or clean Cabin Air Filter

Yes. I usually route it through the left center vent.

Ok thanx cuz I know there's also some vents right under neath the windshield at the end of the dash
So I just want I make sure those weren't the vents u were talking about

I just tried doing this and I don't think I stuck the tube far enough... How far should the tube go down? I was only able to get it about 1/4 before I hit a wall.

Before inserting the tube, did you turn the a/c on and set it to the center button (the button between the up and down arrows)?

This opens the center vent flap so you can insert the tube down to the condenser. But be sure to turn the car off before re-inserting it.

No problem. Follow-up if it still isn't working.

I am not with my car now, but getting ready to put some kilma in tonight...as far as setting the AC to the center vents, how is this done with the B8's climate deal? Should I just shut off the side vents? Stupid question, but just want to do it right ha. Thanks!
