Broken TPMS RECEIVER sensor? Where's it located?

Did you fix your issue in the meantime?
If yes, how?
I have EXACTLY the same problem, after changing the receiver both rear tires are shown blank now.
This car drives me crazy…

They have to be programmed. Why did you change the receiver?

UPDATE on my quest to diagnose and fix my TPMS system issue:

Initial problem:

• LF tire pressure was not registering and Check TPMS System message displayed
• Rotated tires and put tire previously on LF on RR, thinking RR should now be the one not registering
  • LF still showed blank, all others reading correctly

Steps taken to repair:

• Assumed it was not a TPMS wheel sensor issue but related to the TPMS receiver mounted on the rear crossmember.
  • removed original tpms receiver to check plug connection and see if there was anything noticeably wrong
    • plugged back in, drove Jeep around but still no reading at LF
• Ordered a replacement receiver (info on part numbers below)
• Replacement receiver arrived, replaced original receiver
• Started Jeep, all four tired displayed correct pressures and Check TPMS System light was GONE! SUCCESS!!!!...or so I thought.
• After driving for about 30 minutes the Check TPMS System turned back on and now BOTH rears are not displaying tire pressures, but both fronts are displaying correctly

I'm at a loss as to what to do next, but I feel it's related to the TPMS sensor on the crossmember, whether it needs programmed to my Jeep or something power related.

Part number info:

• The 68260735AC is the correct part # for the TPMS receiver AND the bracket
• 52112206AC is the part # for just the receiver

Here is a pic of the inside of my original TPMS receiver. Just 4 pins and an antenna built into the cover, operates at 433mhz.

Open to ideas as to what to do next. I hope this helps others dealing with what seems to be a common problem with little info available on root cause of the issue and how to fix.

Anything new?

Opened my rear crossmember module this evening and found nothing in it.
