I've been looking for a 4WD selector switch for an 07' Tahoe. I ordered one on Ebay which happened to be from an 08' Avalanche which apparently Chevy thought it was a good idea to make them look exactly the same, but the connector on the back of the switch is slightly different. I've looked at GM sites online and one even showed the part on the diagram, but there was no part number next to the item number. I'm fine with new or used, but I contacted a guy on eBay and he's trying to charge $105 which I think is probably too much for a simple used switch. Can anybody help me out?
