Installed "power extend" mirrors onto my LB7. Everything works exept the in and out of the mirrors. Is the only fix a "Tech 2" done by the dealer?? And how much should I pay?? My local dealer wants $89.99.

that is the only fix. but I dont know how much.

Here is a nice write up where you can find out how to service your mirrors. Hope this helps! http://www.dieselplace.com/forum/showthread.php?t=157118

Had mirrors "reprogramed" yesterday.......$32.50 at Mathews-Hargraves Chevy. Works perfect.
