Does a NEW GM 13591958 Control, Heater and A/C Remote have to be programmed?

Hi,
i just got the malibu programmed, but 3 codes that were there before the programming didnt go away and the tech cleared them they came back, then I cleared them they came back UO257 UO1520:00 AND UO151:00 the hvac controls didnt work radio/cd dont wotk and didnt light up along with ac/heater controls and that radio faceplate it seems to be a LIN BUS problem, he said the faceplate radio. AC heater controls are all integrated and must communicate with 1 another, whats weird is the radio works! Plays very low volume on 1 station and it seems the AC/HEATER control is stuck on 1 spped in same heat setting, like the last time before I replaced the orig heater control module, Pat

Hi,

the BCM it was replaced by me in 2020 no water damage had new one cloned, ( from original GM OEM unit, GM flash a business in Missouri there was 2 blown fuses I got it taken care, codes/DTC are gone except U1520 faceplate . Radio, AC/heater controls work and light up now but stabil trak comes on u0121 is been there for years intermittent problem I was thinking. Maybe Poor electrical connection in the CAN bus circuit or ABS module, no rats or mice ever chewed up things/ wires, car is still in Greenville, SC area 158k on it, had it since bought with 11k so no rust or corrosion /salt not a issue. This is a weird problem maybe power assist steering control module? Or harness or wiring? That module is in a crappy spot under the car, Regardless thanks for the full system boot info I am still going to do that I never had the malibu discharged / hard system reboot, maybe Battery disconnected for a few hours that's it, or when replaced in 2022. Thanks,
Pat
