Apparently all of those letters I keep getting in the mail about class action law suits about the 2015 (and similar) Silverado trucks have some merit. My AC isn't cooling (now that the weather is warm) and close inspection revealed a cracked high pressure AC line at the compressor. I figured this out after putting gauges on it and finding 18 psi on the low pressure side (it should be around 35 psi). It seemed to be leaking freon almost as fast as I was putting it in. Ultimately, I ordered new high and low pressure lines (from the compressor and to the compressor), an expansion valve and drier assembly. Add in freon and new belts and I'm looking at about $550 in parts...give or take.

Apparently these trucks are known for compressor issues, high pressure line issues and there's a weld in the condenser that's known to crack. I sprayed soapy water on the condenser and I didn't see any bubbles. Tomorrow, I'll tear it all apart and swap out the lines. I'm hoping this doesn't turn into an all day event....

I've also learned that we now have "stretch fit" belts that don't use an idler pulley. I hadn't run into this before and sadly I didn't find it in time to get the proper tools delivered. However, my neighbor is a former dealer tech and a newly minted Matco dealer. He happened to have a few of the tools GM used to send with new belts, so he gave me a set of those so I can hopefully get the belt on without too much drama.

I'll keep you posted.

Wow...Thanks for the Information. I have a "15" also. So far only the battery went TU, and some sensor the dealer changed under warranty. I have heard that there were problems with the AC, because its all under the dash, but I don't know specifically what was wrong. I hope your problem is a simple fix. Regards.
