I have never heard of such a repair unless car had water damage or a water leak near computer ........
They make new computer connectors and wiring repairs for such problems ...........could always get junk yard connector and splice into wiring harness and they also sell used computers .....sounds like they are trying to blow you out the water and don`t really want to work on it .........after 25 years at GM dealership I have seen this happen ......they proably knocked the labor so high that the tech will be glad to fix it ...if you OK the repair
See how much labot will be ...hell the whole wiring harness is high I know .....think I`d want a second opion eh
