Hi,
Okay, I thought there may be some play in it. Here is what I suggest needing done. The two items don't power from the same fuses or have the same grounds. Even if they did, it would not work at times and not others.
What I feel needs done is the vehicle's CAN bus system needs scanned. Both receive power from the bussed electrical center at the front right of the engine compartment. The term CAN stands for computer area network. All of the modules in the vehicle are tied together within this system. Something must be failing within it.
Here is a quick video showing how and why it's done:

Are you able to have that done? Let me know.
Joe
