Bought the used Traverse about 3 weeks ago, just shy of 100,000 miles. The salesman was great to deal with, and has been making sure I'm happy with the car. He noted that the rear bumper was slightly damaged and had a broken license lamp, so he wrote on the "we owe you" that they will replace the bumper cover and license lamp. The car is in great shape and has been well maintained.
After I got it home, I noticed the power mirrors don't work, and it turned out the fuse was blown. I conjectured that maybe somebody tried to adjust the mirrors when they were frozen with ice, and blew the 2 amp fuse. Also found the the rear wiper blade was tearing and needed to be replaced. The part stores don't have the fuse or the wiper blade. Stopped by the dealer to buy a fuse and a wiper blade, and bumped into the salesman. He insisted on adding those the "we owe you" items at no charge, since the dealer was out of both. He promised to have the service folks do both of those when they fix the bumper.
Dropped it off Monday this week to have the bumper, license light, wiper blade, and fuse fixed. They even gave me a loaner, free of charge. I saw that the fuse was not mentioned on the work order when the service manager had me sign it, but he had the "we owe you" sheet in front of him, so I pointed it out. He wrote on the work order to replace the fuse and promised to look into fixing the power mirrors.
Get a call Monday evening, and all are fixed, except he says his technician determined the fuse was good. I assured him I checked it thoroughly with an ohmmeter, and it was open. He promised to look into it Tuesday and would call me. Tuesday goes by, no calls. Wednesday I call, and he thinks the problem is in the wiring between the switch and the body control module, but it's not approved to repair it. If I want it fixed, it will be a warranty claim with a $100 deductible. Hm, I think I'll look into it myself, but they do still owe me a fuse. He still insists the fuse is good.
I get it home, and confirm that the fuse really is bad. I take the blown fuse in, he concurs it's blown, he says he'll get a replacement, but since the parts counter is closed, I can pick it up Friday evening. Fair enough. Friday afternoon, he calls and asks where I got the fuse from. The fuse box under the dash, where else? What location? The one marked "pwr mir" in the diagram. Not an encouraging sign. Already getting a bit annoyed that I was led to believe they were going to fix the mirrors, and getting the fuse seems to be like pulling teeth.
Saturday, I talk to the salesman, and mention these problems. He's amazed and grabs the general manager, who agrees, I have been patient and there's no reason I shouldn't have a replacement fuse as promised. The GM walks back, and a minute later, I have both my bad fuse and a brand new fuse in hand. He even offered to have them fix whatever was wrong with the mirrors. No thanks, I'll look at them myself first, and thanked both of them for their assistance.
Now that I found the schematics for the mirror circuit online, and a Youtube video of how to pop the mirror switch out, it turns out the service manager was full of it when he said it was in the wiring to the body control module; the BCM doesn't control the mirrors at all. In fact, it's a very simple circuit. I unplugged the switch, put a sacrificial spare fuse in, and measured battery voltage at the switch harness. Used a 9-volt battery with some clip leads, and found I can energize the wires to each mirror and make both mirrors move up, down, left, and right. Switch seems to be bogus, but I found a replacement on Amazon for $20. Time to make this diagnosis? About 15 minutes.
Don't think I'll be trusting them for any more repairs. I'm not even sure they looked at the mirrors at all. I'm still astounded that they determined the fuse was good, I'll bet they were looking at the wrong fuse, if they looked at all.
