mra32 Posted February 10, 2011 Report Share Posted February 10, 2011 just had this happen to me. there is a diagram on the core support. One goes to a tee and goes to the MAP sensor and the FPR (this is super important) the other small one goes to the HVAC system to actuate the different vent selections, The bigger one probably goes to the trans Quote Link to comment Share on other sites More sharing options...

mfewtrail Posted February 10, 2011 Report Share Posted February 10, 2011 The entire plastic vacuum "spider" should still be available from almost any GM dealer - I think they were around $30-35 a few years ago. Quote Link to comment Share on other sites More sharing options...
