Notes
GENERAL MOTORS CORP. 99041

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.

The problem is, when in 2wd when you brake on slick surfaces you can hear the ABS system ratcheting or clicking and all the brakes are locked. The car just slides. The reason I asked my original question was to see which parts the dealer was supposed to replace. I bought a new 2wd/4wd selector switch (the one on the dash) and installed it, the system seems to be working correctly now, but I will have to wait until we get some more weather to really see if she's fixed.

NOW I UNDERSTAND. THE 4WD SWITCH IN THE DASH SHOULD HAVE NOTHING TO DO WITH IT. WHAT THAT RECALL DOES IN REPLACING THE VACUUM SWITCH AND ACTUATOR SENSOR. ITS BECAUSE WHEN YOU HAVE THE TRUCK IN 2WD THE VACUUM SWITCH DOES NOT RELEASE THE FRONT DIFFERENTIAL. THE TRANSFER CASE IS NOT CONTROLLING THE FRONT DIFFERENTIAL BUT BECAUSE THE VACUUM SWITCH FAILS IT KEEPS THE FRONT DIFFERENTIAL LOCKED. WITH THE FRONT DIFF LOCKED THE FRONT DRIVE SHAFT WILL SPIN BUT IT IS NOT ENGAGED IN THE TRANSFER CASE. I HOPE THIS MAKES SENSE.

Yes that makes sense. Well maybe now that the recall has been done, all the front axle hardware not spinning will give me a little better mileage. Thanks for the help.
