Good evening, my father has a 2005 RL and had to change out his factory battery this afternoon. Once changed, he had to re-enter his codes for both his nav and radio. He still does not have any controls of his air conditioning. Is there a code to activate this as well. He is not very technologically advanced and was planning on waiting until tomorrow morning to call the dealership. Any help is greatly appreciated.

 

There is no code to activate the AC. Something else is going on and it may be worth a trip to the dealer.

BTW, welcome to AZ!

 

was he able to star the car? I had similar issues a month ago when I swapped out the battery on my car.
