#6 of 15 Fan Turning On and Passenger Floor Leak and few other issues with CX-9
Nov 13, 2010 (7:00 am)
I have a 2008 CX-9 and its warranty is expiring in December 2010. Overall I've been very happy with the car but lately it has been having few issues. I noticed the fan would come on after I turn the car off. Also I noticed that there was lots of water on the passenger side mat. Initially I thought I had dropped a bottle but on investigation my wife noticed that It was leaking from inside the dashboard. Took it to the dealer in Staten Island and he said the evaporator drain is clogged and it meant that water was not draining. According to him if dry leaves fall and crumble through the windshield grill clogging this drain. Of course now it is all moldy in there. He told me it is a maintenance issue and Mazda would not cover it as part of the regular warranty. So charged me 300 bucks extra on top of the 600 he is charging to to the 30,000 mile servicing plus 100 that he is charging to hook the computer to find why I'm having all these problems. Is this all normal to pay so much while the car is still in warranty? Also this drain problem seems like a design flaw to me. I have had a honda for 10 years now and never had such issues. Any comments would be much appreciated.

A/C fan come-on issue requires replacing two relays. There is a TSB for it.
30K service is a waste of money.
Do mantanence by the schedule in the owners' manual.
Dealer loves those XXk service package - big ripoff.
Especially the cabin air filter. Dealer charges you $80 easily, when it actually costs about $10 for the part, and 1 minute to install it.
I don't have this problem, but I do clean debris regular for any vehicles I own(ed).

What Ceric said X 2 ----^
BTW, the relay part number is G115-67-730, you will need two of them one for the front blower and one for the rear one.

If you haven't found it already, the AC evaporator drain plug is located on the driver's side, under the vehicle, on the upslope for the "transmission hump" & under the silver protective sheeth. The drain plug is a white plastic grommet which makes a sharp upturn immediately. Trying to clean the drain tube with a hanger is difficult but an air hose, if you have a compressor, works well. Be prepared to get wet if the evaporator is full & you've already gotten water on your mats as the water will come gushing out after the block is cleared.

I am having the same problem, went under the car but couldn't find the white plug, i am afraid to end up making things worst, Did you get it done? Was difficult? Could you take a picture of the plug? I am on a really tied budge and don't wanna take the car to the dealer . Any help would be great appreciated. Thank you, Daniel.

I'm heading out the door soon & don't have time to take pics but if you find the silver heat shield on the driver's side of the underbody, you're close. This shield would be in the area next to the driver's right foot. Peel the shield back a few inches & you'll find the white plug - it's less than an inch in diameter. As mentioned, I tried a hanger with no luck so you may need to find an alternate method to clear the obstruction. Good luck!
