Customer Question

Some of my gauges on my GMC 2003 HD SIERRA are not working. In the past, I would disconnect the battery and they would reset and work fine. This time no luck
JA: Have you tested the battery with a voltmeter? And can you see if it's leaking or not?
Customer: Have not
JA: Are you fixing your Sierra yourself? What have you tried so far?
Customer: Did not see any leaks
JA: Anything else you want the mechanic to know before I connect you?
Customer: My truck is smoking on idle and when I jump on it
