I have a 87 gn with 14,000 miles in excellent shape with the exception of the power antenna. It doesn't work and I'm no electrician by any means. I ordered a replacement from gbodyparts.com and when I received it I plugged it in to check before doing the install. Nothing! I searched on here and found schematics and troubleshooting guides from vortecbuicks and some others. I've been trying to follow steps to trace if everything from the radio through the relay up to the antenna is correct but like i said i'm no electrician. If anyone has ideas of things to check please let me know. Also are there other options if I can't resolve the power antenna problem such as fixed mast etc.?
