I broke the power antenna mast and can't seem to get the mast out of the power antenna motor, I thought after removing the mast I could run the antenna up and the plastic cable would feed out the motor; however, when it gets to the end of the cable it seems to be connected to the motor. Do I have to get into the motor to diconnect and reconnect the new one? Also, when putting the rear window up it goes part way and then stops, it takes about 3 times with reseting the key to get it all the way up. would this be a switch or resistor problem and were are they located? Thanks
