My 2011 Yukon radio and all or most alarm chimes quit working. I replaced fuses 41, 42, 46 (under hood) and fuse 22 (interior). None of the existing fuses appeared to be bad. I was told to connect loose +/- battery cables for 5 minutes to drain capacitors and reset computer center? My new battery slowly drained two days after the radio quit working? Please advise.
Thanks,
Fred
