I have a 07 Tahoe LTZ Driving sometimes the dash gauges lose power and stop working. The a/c stops cooling fan blows no compressor power. then it comes back on the door locks click and bells ring it say's service Stabilitrac and parking assist, the trans shifts really hard and cruise control won't work. If you stop and turn ing. off and start it back it resets everything and works fine till it does it again. sometimes it goes a month or so without doing it. sometimes three or four time s a day. ????????????????????????????? spent 700.00 at dealer said they fixed some wires on engine harness but still has problem?
