1991 Infiniti G20 Power Antenna Motor Test, June 18, 2017

Описание: The power antenna mast on this 1991 Infiniti G20 has been for about 14 years. The electric motor works fine, but the antenna's mast broke. Specifically, the plastic rope with teeth inside the antenna snapped. As a result, the antenna mast can be extended, but once extended, it cannot be retracted.

I bought a replacement antenna mast and removed the old broken one. The old mast itself was easy to pull out, but unfortunately, parts of the mast's broken plastic rope remained inside the antenna motor housing. I ended up having to take out the motor assembly itself(after removing the car's jack, the jack mounting bracket, and disconnecting the motor housing's water drain pipe).

After that, I took apart the motor housing and removed the broken pieces of the antenna mast's rope. I decided to test the motor, as you can see here in this video. The motor turns back and forth when I hit the power button on the car's radio.

Unfortunately, the repair was not completed successfully. The replacement antenna mast that I bought did not fit properly. The tip of the mast is different, and it's missing a stopper at the base of the mast that would prevent the entire mast from being pushed out of the car by the motor. So it looks like I have to buy another replacement mast, OEM this time, but at least the hardest part is done.

About a week after making this video, I got a Nissan OEM power antenna mast in the mail(bought it on eBay for about $50). Being an OEM part, it has the correct tip as well as a stopper at the base of the mast. It was installed, and it worked fairly well(see video:    • 1991 Infiniti G20 Power Antenna Mast Repai...   ).
