A/c turns on bby itself

[makan.dm]

When I turn off the car, the A/C turns on by itself. What should I do?

 

[codeman94]

Replace the front blower relay, mine was doing this until I replaced it. I got my replacement part from my local Mazda Dealer for $9.80 and it took me 2 minutes to install the new relay.

makan.dm,

quick question, how long does the A/C stay on after you turn off your car ?

won't it eventually drain the battery ?

It stay on really long. I drive it after that, and turn it off again and then it worked

This looks like it would fix your issue. Good find @avidien

It could stay on for 30 secs max.
Replace the two relays. Common issue.
I thought new model years have relays that were better designed.
Hmmm..

OP's 9 is an '07... I don't expect any blower issues, plus warranty

This totally happens to me randomly. Thanks for the post - going to put the new relay's in this weekend.

Sorry. Did not see the OP's model.
Relays are common problem to '07 and early '08 like mine.
After replacing mine, never happened again for the following 5 years.

I had that issue on the rear ac in my 2010...like they said - 2min fix

Hello everyone.
regarding this detail of the relays fans, a very fast and avoid buying possible solution is to remove and gently light shocks with a screwdriver ... and ready goodbye problem!

if symptoms persist ... repeat dose or renovate parts.

Greetings.
