I took my GMC to a dealer to have this recall done. They did not replace the 2wd/4wd selector switch on the dash. The service manager said they replaced a vacuum switch, a wire harness and 2wd/4wd switch under the hood. This did not fix the problem. Can you tell me if they should have replaced the dash switch. The part number for the dash switch is 15152504.
