ok guys here's a simple DIY u can do to get rid of that nasty smell when u flip the a/c on. it took me 1 hour to do with taking pics, but u can do this in under 30 minutes. the dealer sells this service in a combo pack along with replacing new model cars' cabin air filter totaling $100 with tax
u can do better things with your money than that. here's what u will need:
jack stands or wheel ramps
A/C odor kit
i bought this kit from the dealer for $23. LARGE PICS AHEAD!!!!
sorry i couldnt seem to flip it around
i'm still trying to fidget with the photobucket features so bare with me here guys.notice how the tip at the end has a cone shape. this end u wedge into the evaporator drain tube. see below
this is the tip here. other kits just have just a long hose without this cone wedge at the end, whatever kit u buy be sure it comes WITH a hose bcuz u cant do this procedure without it.
next put the car on jackstands or use ramps like me
slide under the front end towards the passenger side and look around under the power steering pump. u should see a small black hose sticking out from the firewall, this is the evaporator drain tube.all cars have one. if u cant find it turn the a/c on and look for drops of water coming under the car and you'll see it. here i have the hose cone adapter stuffed into the drain tube. if u went in head 1st under passenger side this is what you'll see.
that boot is the steering rack boot, u may need to actually use jack stands to lift the car high enough to reach the tube. i'm not a big guy so it wasnt an issue for me
. the evaporator core is subject to growth of fungus, mold, etc. this can produce a foul smell when u flip a/c on. if your drain tube is clogged then this problem can get worse. its also bad in hot and humid areas. the cleaner is basically a foam which expands to fill the evap core and washes out all the nasty shit growing in there or stuck up there. i strongly suggest u hold the hose with 1 hand and use other hand to hold the cleaner can. the hose can fly off the can with pressure and spray everywhere, this is why u NEED GOGGLES!!! CAUTION: once u empty the entire can into the tube and remove the hose, the foam will begin to liquify very fast, wear goggles and put a drain pan underneath to collect runoff. this takes about 10 min to fully drain evap core.
Use a drain pan and wear goggles!!!!
once all the liquid drains out, turn the a/c on to max cool and get the other cleaner out and spray the a/c vents on the front of the car where the wipers are. u should have 3 vents.
this is where u spray the cleaner.
u need to set the a/c to max cool and set it to pull in OUTSIDE AIR, NOT recirculating air. it has to suck in the cleaner from outside to work right. spray each of the vents liberally then switch the controls to heat and spray again all vents. this 2 step kit works really good, others just sell the a/c vent cleaner or the evap cleaner by themselves, but u should do both to get the best results. this can help u if have allergies too. Now u can enjoy clean smelling a/c
