#22 of 31 Re: Front Fans Blow After Turn Off [stonpony] by debbiejay Sep 08, 2009 (6:40 pm)
Replying to: stonpony (Sep 08, 2009 9:08 am) Thanks! This is super helpful. My dealer tech seemed baffled since the problem wouldn't happen when the car was with them. Now I have something to go back with since I am still in warranty. Really appreciate your help. Replies to this message: ceric (Sep 09, 2009 12:58 am)

Replying to: stonpony (Sep 08, 2009 9:08 am) My CX9 is out of warranty so I asked my buddy that works at Riverside Mazda to hook me up with a copy of TSB 07-008/09. I read through it and was very simple and straight forward. I bought the relay that the TSB said to replace (part# G115-67-730) replaced it (under hood relay box closest to the driver's side fender) and up to right now no more occurences.
#25 of 31 2007 CX9 Rear Air Stays On by mford1970 Jan 11, 2009 (3:15 pm)
I think this car has an electrical gremlin. The trip odometers reset themselves regularly and the dash dim light (for when the headlights come on) also resets itself. Now, within the last two months, when you turn off the car the rear air comes on. The first time my wife just turned the car on and back off. This would fix the problem. Today when it happened, I turned the car back on and turned off all air controls. I then turned the car off and the rear vents were still blowing. I turned the car back on and off again. The rear air remained on for over six minutes. I turned the car on and off again at this point and it finally turned off. This has happened four times in two months.   Has anyone else had this problem or the odometer ones? I took it to the dealer three months ago when the check engine light came on and the car started to run real rough and then would die. Took them three days to figure out a vaccuum line had broken near the firewall. They never could figure why the meters reset. Replies to this message: ceric (Jan 12, 2009 9:14 am)

Replying to: mford1970 (Jan 11, 2009 3:15 pm) Did you install accessories recently? It seems like some electrical short exists in your vehicle (that causes improper grounding). You need to have it checked out by your dealers before the OE warranty expires.
#28 of 31 air conditioning stays on when car is off by bigdog19 Oct 28, 2009 (3:04 pm)
we are NOT car people. have a 2007 Mazda cx9. when you turn the key off and remove the key the air conditioning stays on and you can still make the windows go up and down. the A/C turns off after about 30 seconds to a minute. is this some new thing or is our electrical system messed up? thanks in advance for the help.

Replying to: bigdog19 (Oct 28, 2009 3:04 pm) There is a window of time that allows you to still use the windows, this is normal... the ac/ staying on after the car is turned off is not normal...and there's a known issue with it. There's a relay that hangs open too long. Ask your dealer about it. It's not a difficult repair.
