more problems with the z28
second the radio is going off at random and when that happens the windows do not work
third the security light is coming on and preventing me from starting the car
any ideas on any of this i really don't have the money to take it to the dealer to get checked out

The security light no start issue sounds like the pass key system is failing. You can pull apart the steering colum and repair the actual ckt or go to the other side of the car and setup an inline resistor(s) to the bcm with a switch to ground.
