I recently removed and replaced the high and low beam bulbs (left side only) in my 2009 Azera. I did not disconnect the negative battery cable. Now, when I press "Lock" on the key fob, the doors lock but the lights don't flash. They do flash when I unlock the car with the fob. The locking system works, except for the lights when locking the car with the transmitter. Turn signal, high and low beam lights work when turned on. Fob battery is OK. Is there something I'm overlooking?
