Please try to keep this in one thread, you had already asked a question about the BCM, and posted about the sweeping gauge issues, to make it easier for you to get help I have merged the threads for you.

my gauges sweep and stay to the right side.every couple of days the gauges move closer to the normal position example ..tach is reading at Idel..7000rpms ...gas is at 300 o clock..temp at 630...it changes from day to day and how many times I shut the car down and restart. I sent out my gauges to be repaired once. Everything was good.Now the gauges are not working
tks
