I have a 2008 CX-9 and the fan problem just surfaced a few days ago.

Thanks for the TSB info Wrencher...

 

I had the same issue intermittently in my 2007 for the past year and a half or so. A few months ago I ordered the new relays per TSB (light blue), installed in 2 minutes and since have not seen the problem reoccur. If you are having this issue I recommend replacing them to resolve.

 

Thanks, wrencher. Got the parts for my 2007 CX-9 too. Problem solved. It started right after the air bag recall was done when I brought the vehicle in for another issue.

 

WOW!!! This is why networking works!!
I am so happy that so many of you have been able to get this problem resolved from one member making one post.

GREAT!! I LOVE IT!!!

Thanks for your in site and information, Wrencher.

 

what would we do without the internet eh?

 

Oh, there was still networking before the internet. It was just a lot slower and usually one-on-one communication.
You had to do more "homework" back then.

 

I would like to know what the part number is for this relay and can this be done by the do it yourselfer. Where is the part located in the vehicle. Also how much did this part cost. All help would be greatly appreciated.

 

TSB 07-008/09 The relay part number G115-67-730

 

my 2008 is doing the same thing. I got it to the dealer last night - 96.00 just to look at it...left it and need it back by tomorrow. No one here has posted what is causing it.

 

Olga...read the whole thread. A TSB was published quite awhile ago for the blower/fan issue. There's an inexpensive and simple fix. You need to replace a heater relay. The relay part number G115-67-730.

There's a TSB out on this, check with your dealer.
TSB: 07-008/09
