Chevrolet Repair: 1995 astro van, dash vents, heater blower

Question
I just bought a 95 astro van. The heater blower only blows out the dash vents. It does not matter what position the lever for defost, ac, vent or heat is in. Also the blowers will not blow in the high postion. They will blow on the lower setting just fine. Any help will be appreciated. Thanks, Jonathan

Answer
Hi Jonathan.... check the heater control....if it is vacum controled check for vacum...if electric...check for power...in and out of the control....check the fan switch for power on the high setting...if none replace the switch....most heater control problems are in the control....hope this helps
