Escalade Mirror Swap - Glass Replacement

[Joey Sal]

Hey guys, this past Saturday I successfully converted my tiny mirrors to the Escalade mirrors and I love them! got a good deal off ebay and was lucky enough to even get the right color! only issue is the passenger side blindspot indicator is not lighting up. My guess would be that its burnt out since it was working fine on the mirror I removed. question is how do I replace just the glass? thanks!
