whistling noise 2009 gmc sierra
#11
After reviewing the recordings the dealer decided we need to change the alternator, had it changed yesterday and so far so good, will need to see if its a issue next winter but I beleive we have solved the problem, received excellent service from the dealer and a GM rep working on the case, it was frustrating at times for all due to the intermint nature of the defect, the best tool in the end was a camera slected to movie mode to help the dealer see/hear what was going on.
Thanks,
