heater problem

  

thejum57 -> heater problem (12/4/2006 9:46:49 PM)

I replaced the bottom radiator hose on my 87 Cavalier conv. When I refilled the radiator I put the heater control on heat, and turned it on. Heat comes out fine, the only problem is now it only comes out thrugh the dash vents, or defrost. Nothing comes out by the floor now. Everything worked fine before the hose replacement. Any suggestions???

I have a similar problem with my 91. It could be the diaphrams that control the diverters in the heater/ac module or the color-coded vacuum line that go into them. You  have to pull out the glove compartment to get to them.
