well to clarify all the answers to the heater mess i have found out what has done it..........
on the blower motor behind the glove box there is the plug that goes into the top of the motor(blower) it self and it had a bad connection in it and if you have the car on and the heat on it will come on so i jimmy rigged a string from a shoe to hold the cord inplace and anchored the cord to help hold it in place there is only one way to know if it will stand the test of time
Good luck
