crazy 02 escape problems

my escape has been acting crazy for the past few months. first it got stuck in park and i had to have it towed to the dealership. well of course they said that there was nothing wrong with it, and that i probably wasnt pulling on the shifter hard enough... so as soon as i get home from the dealership i put it in park, stuck again. it finally came out a few days later and i have kept it in neutral ever since. also the radio comes on and off when ever it wants. if it goes off in drive you can usually shift to neutral and it will come back on, it also goes off when you turn on the blinker. the reverse lights will not work when you are in reverse however the stay on when the car is in drive. this morning it wouldnt start, i turned the key several times and every time the doors would lock and when you turn it back they unlock. its a pain in my @$$:banghead: i was wondering if anybody else had similar problems, or knows whats going on
