Keys, Doors, and Windows Programming the Power Windows If the battery on the vehicle has been recharged, disconnected, or is not working, you will need to reprogram each front power window for the express-up feature to work. Before reprogramming, replace or recharge the vehicle's battery. To program each front window: 1. With the ignition in ON/RUN or ACC/ACCESSORY, or in Retained Accessory Power (RAP), close all doors. 2. Press and hold the power window switch until the window is fully open. 3. Pull the power window switch up until the window is fully closed. 4. Continue holding the switch up for approximately two seconds after the window is completely closed. Pull the sun visor down to block glare. Detach the sun visor from the center mount to pivot to the side window, or to extend along the rod, if available. The window is now reprogrammed. Repeat the process for the other windows. 2-21 Rear Window Sunshade On vehicles with a rear window sunshade, the switch is on the console to the right of the shift lever. The sunshade only operates when the ignition is in ON/RUN or ACC/ ACCESSORY. To open the sunshade, press and release the switch. The sunshade will fully extend. To close the sunshade, press and release the switch again. The sunshade will fully close. If the vehicle is shifted into R (Reverse) when the sunshade is extended, it will automatically close.
