“I purchased my 2004 Trailblazer of the original owner with 35000 miles on the speedometer. At 75000 miles the door locks started clicking as if locking and unlocking. I took it to a chevy dealer and the mechanic said it was definitely strange and I would need to make an appointment to have them look at it. Just him saying definitely strange to my ears said expensive. My sister had the same vehicle different color and hers had the same problem. Now how strange is that? I broke the appointment and got used to the clicking. Sometimes it would stop for a week or so and click some more. …”

We have taken it to a mechanic. …”
