Battery was dead this morning. Bought new battery and installed. Still have the 4 buttons for the rear wiper, washer, A/C and cabin blower flashing. What does the flashing mean and how do I get it to stop

try this,but if your ac doesn't work there will still be flashing lights

1] start engine
2] slide AC controls to the left
3] set vent to vent-face
4] fan control to full -high
5] Press AC (snowflake) Button and Rear Washer Button At The Same Time (Both Together)
6] Hold until All Lights Illuminate Together
7] Release AC & Rear Washer Buttons
8] Unit will Cycle for a few minutes (seams like a lot longer)
9] When done - lights will stop flashing.

If it doesn't work the first time - try it again. Somethings also need to have the parking brake applied to work

Thank you did it and it worked
