hi all! This is my first post but I have been reading them for years. So here is the deal. A friend left his 2001 sitting for 4 months outside uncovered! I offer to resurrect it. We ended up replacing a dead battery, so dead that the we had to pull the emergency cable from under the passenger side wheel well. We got it running and now we are down to only 4 problems. power locks do not work, key fab doesn't work, radio has no power and the window switches don't work. The windows lower when the doors open although the driver side gets stuck sometimes. They lower when the top goes down but nothing happens when the switches are pressed. is there a way to check switches without spending $100 on new switches? Just yesterday the windows were working for 24 hours. HELP!!!
