Help with any of the following problems will greatly be appretiated. Thanks in advance


Problem #1:

The button on the key doesn't unlock/lock the door. The lights change from green to red and vice versa on the door but it doesn't get unlocked. And when I unlock the door from the passenger side, it only unlocks the passenger side door. I have to manually unlock all the other doors. If I try to unlock the driver side door using the key and turning it, it doesn't work. Anyone know what is wrong here?


Problem #2

Radio just shut off about a week ago and it isn't turning back on. Do I need to disconnect the battery to get it to work again?


Problem #3

A/C randomly shuts off once a week and I have to open up the hood and take out fuse #21 I think its fuse #21...and put it back in... Last time the a/c did this, I checked the fuse..and it was fine but I still had to take it out and put it back in to get the A/C to work... If the A/C is on....the lights and everything will still be there..but the A/C just wont be running.. If this a/c is off..I won't be able to turn it on..it'll be like the buttosn just don't work..
