I have a 1996 Blazer and I have been having problems with the four wheel drive. found that the switch on the T' case was bad and replaced it. Now I have a Vacuum leak at the switch. 3 pin vacuum connector is bad. I am having trouble finding a replacement. Any help finding a part number or part would be a great help.

Thanks

Steve

 

Is the connector too loose around the prongs? If so wrap some duct tape around the Prongs to make them larger.

 

Edit: Nevermind! See below.

 

The connector should be OE part number is 15537463 according to NalleyGMC.com's Parts Diagram & listing (click on the PN for the diagrams). You might want to confirm that with your local GM dealer before ordering as some of the other diagrams seem to conflict a bit, but according to the image below, it does appear to be the correct PN:



One of the diagrams shows some additional 'connectors' that are likely hard plastic lines to adapt between the rubber mutli-port connector PN-15537463 to the 3 individual vacuum lines. You can probably make them yourself out of normal hose barbs often available in assortment packs at your favorite autoparts store.

 

Thanks swartlkk for the help.
That is the connector and have one on order.
