My battery started acting up (slow cranking when temp drops to 30-deg and below). I went to Sam's Club and picked up a 34 (upgrade from a 24) with a higher (850) CCA for $85.00 with a 3-yr warranty. I kinda panicked when after installing the new battery, the sunroof and the windows didn't work. Found out later that I needed to reprogram the windows and sunroof by going thru the cycle. I thought I did something and shorted something and blew the fuses.
