Satellite Radio Signal Loss in Winter

hairybumcrack · March 15, 2020

I own a 2014 Sierra and over the past two seasons, my satellite radio doesn't work once temps get below 40F. Initially I thought it was the antenna in the first season however when I made a trip down south, once the temp was above 50F my satellite radio would work. Once I drove back north, gone.

Before I start replacing things, I just thought I'd ask if anyone else was experiencing similar issues. I've done a search here and on the internet and there is nothing that aligns with the symptoms of what I'm experiencing. I might as well cancel my Sirius subscription from November to April each year.

One of the many quirks with this truck (original owner). Cannot believe the amount of recalls on this truck as well and the shifting clunks are unbelievable.

Needs an antenna super common

So I was doing more research on this and as I have Nav, if the antenna fails then the GPS also fails to work. Well the GPS and my Onstar works fine but no XM radio reception. If someone has a part number for the antenna, that would be appreciated otherwise I'm just contacting the local dealer. Thanks.
