yup, no matter what selection I have my temp control on, it always blows out of the defrost. the fan still blows fine, it will go to heat and a/c, just not out of the regular vents. any ideas on the problem.

Or, on your 98 4x4, the vacuum leak could be in the Pulse Vacuum Hublock system, a notorious leaker that shares the vacuum reservoir with the HVAC.
