Question
i have a 96 el dorado and i am trying to replace the power antenna assembly. i have removed the old one, but have come across an odd problem that i am probably overlooking an easy answer to. the plastic nut assembly that screws in on the outside of the fender is on the old antenna shaft still and although i could just cut it to get the nut off, i cannot figure out how it is supposed to come off, and then how to put it on the new antenna i get. any information would be very helpful. thank you.
Hello,
A special to known as a spanner whrench is require to remove and replace the nut. You will not find this tool in a parts store. GM mechanics had to purchase this tool themselves. A dealer might have it, but doubtful because specialty tools were lost or stolen.
You did not say why you were replacing the antenna. If the mast is broken, you can buy a mast kit that takes only minutes to install and is much cheaper than the motor.
What I have done to istall and replace the nut is heavily pad the surrounding area of the fender and used a needle nose pliers inserted into the slots to unscrew and tighten, but you will slip many times and that is why you have to pad the area arond the nut.

Expertise
Alarm system questions cannot be answered on this forum. These systems are not what I can answer. Without being physically at the vehicle and not knowing what kind of electrical service has been done on the vehicle, there is no possible way to give an accurate answer over the internet. My expertise is in Ignition/key based anti-theft systems. These issues include GM VATS (resistor chip in key blade) PASSLOCK (MRD)-ignition lock rotation based, no special ignition key and the PKIII Transponder (computer chip in key) systems. These systems are not alarm based and are integral with the starting of the engine. This is why I cannot diagnose alarm problems without physically looking at the vehicle: Alarm systems are a completely different annimal than ignition key/lock based anti-theft system. Many alarm questions come from vehicles 10 years old, and since older, many hands that had been involved over the years.I am an expert in all GM factory (ignition/key based)systems. Alarm system questions pose to many situations beyond my knowledge as to what has been done to the vehicle over the years. Some guy may have actually wired the stereo into the alarm system. Who knows? Over my past 30 years in vehicle wiring repair, I have seen unbelievable wiring disaters done by guys that consider themselves "mechanics." I have seen stereos and alarms intalled using surgical tape. I have seen modules burn up, un-fused circuits, wiring jambed between the doors and even lamp cord used for a starter kill. To answer alarm questions over the internet without examining the vehicle is like asking; What does it take to remove a dent?
