I strongly recommend to everyone that when ordering your mirrors you order them for a 2500HD. They have the same part number. No one will honor the warranty if you order them for a 1500!
Wanted to share my warranty experience with AM Auto. Simply put, don't buy from them ever! Not worth the $150 savings over 1A Auto to deal with their bullshit. The power fold out broke on my drivers mirror only a month after being installed. AM Auto claimed the mirrors weren't made for my truck so they weren't going to honor the 10 year warranty. They also refused to acknowledge the upgrade kit that's included in the box (I used Phil's wiring harness). After a 6 day email battle, they refuse to offer a phone number for their customer service department, they agreed to allow me to return my mirrors with no restocking fee but I have to pay shipping to send them back. I had to threaten them with contacting the Better Business Bureau.
I called 1A Auto. They also said if my truck didn't come from the factory with power folding tow mirror they wouldn't honor the warranty either.
Against my own advice, I ordered another set from AM Auto. I used a friends PayPal and had them shipped to his house so they wouldn't be linked to me if I have to make another warranty claim. More importantly, I ordered a set listed for a 2500 but had the same part number. Hopefully they'll honor the warranty if I tell them I have a 2500 LTZ.
