2 failures in same week, are they related?


Recommended Posts

Hi Everyone,

I have a 2014 Silverado V6 LS. Last week my AC went out for the second time. Truck has 44K miles so is out of warranty. The first time they replaced the defective hose issue I have read about. I have not diagnosed the latest problem yet but was planning on doing it this week. Then today, I was running errands and I heard a loud squeal and seconds later I had no assisted braking and had to really push down to stop. When I got home I looked in the engine and saw the belt had snapped. I purchased and installed a new one and fired up the truck. The squealing was loud and when I looked the vacuum pump was frozen and the belt was just spinning on it. I also noticed 3 days ago that the electronic thermostat number was stuck at 51 degrees most of the day even though we are in the mid 80's in Dallas. Either this truck is having a really bad week or there is a connection. Any ideas?
