Can I replace a malfunctioning weather sensor?

Hi, I have this unpleasant situation with my Fenix 3 w/ OS 8.9, which I’ve bought just 3 years ago: suddenly , I can’t get temp, pressure or altitude readings, just a dash or nothing in return. Trying to calibrate the altitude manually will result in a ‘calibration failed’ message. The GPS method returns the altitude from sats but can’t set it either (same fail message).

So, GPS, compass and everything else are working just fine, all except this all-in-one ‘weather’ sensor - for temp&airpressure - that comes solded on the chasis, separated from the motherboard and connected through 3 pins.

Outside cleaning/rinsing of the sensor inlet ports and factory defaults didn’t solve anything.

As warranty expired and Garmin policy exclude service (allegedly), is there any way to fix this? :)

Thank you
