My 2003 limited is having a few issues with the back hatch. My rear wiper isn't working and the key won't roll down the back window, though the window works fine with the button on the dash. Coincidentally or not it happened after I took it to Jiffy Lube for an oil change. They disconnected my battery to clean the terminals. I looked for blown fuses but all look ok. Is there something simple I'm missing? Thanks!
