When I turn the car off the rear ac will continue to blow air for approx 30 seconds. Anyone know how to correct this.
Thanks for the help
 
Two relays need to be replaced. New ones are of a better design.
Search the forum for part # and how-to if you want to DIY.
If not, dealers should know this very well already. The relay is about $5-10 each.

P.S. the old relays have issue with grounding when it happens.
Charges remain in relay causing the A/C to continue operate.
It will shut off after 30 seconds, however, due to accessory power cut-off.
