Happy to see URO support active here.

I acquired one of the Auta2050 masts with motor from Pelican a while back but never got around to installing it.

I installed it yesterday in my '91 300E.

Connected red to constant power.
Green to switched power.
Black to chassis (ground).

However, all Im getting is this buzzing sound. I made a video of it, attaching below. Is the motor shot? Antenna itself has not moved with radio on just yet.

Thank you for the PM. However, since the PM, I haven't heard back and it's been a few days.

I double checked with a workshop and the brand new URO antenna motor is infact siezed well before I got to use it.

Please advise on solution soonest.

Wow, you have provided some excellent information. I was impressed with your work on such a helpful article.
