2015 SLE Electronic Problems

[firerescuef2]

Hello all,

I have a 2015 Sierra 2500HD SLE that I purchased about a week ago. I have a active subsciption to but onstar and sirius XM but neither seem to work. Along with the compass, sirius XM always says no XM signal even after sending 10+ refresh signals. Onstar I have called and they just say that they cannot connect to the vehicle. Green light is on and I can call out but no one else can call in. Im thinking this is more of a vehicle electronics problem then a onstar or sirius problem, your thoughts? I cannot even use the MYGMC app on my phone, Im logged in and everything but all I get is that it cannot connect to the vehicle. Would there be any kind of fuse or relay that could be tripped that would cause this?

Also last night my heater controls started having a mind of there own. most of the time the HVAC control would be stuck on defrost, or a mix of defrost and upper vents. temp, fan speed and A/C all worked fine but the direction to where you wanted the air to go wouldn't. This is the standard one zone HVAC by the way.

Thank you for any/all help.

Im thinking it will go back to the dealer......

***UPDATE***

Dropped it off at the dealer. 3 hours later. Faulty antenna, all the problems with the HVAC were corrected by a system reset. (Disconnect battery)

Just incase anyone else runs into this issue.
