Buick/Olds: 1992 Buick Skylark heating @ A/C problem, buick skylark, coolant levels


Question
My 92 skylark heating @ a/c both stopped at the same time. The heater blows cold air but not hot. The vacuum operated doors all seem to be working good and the heater core gets hot. I changed the thermostat. The a@c blows only air, not cold air. Any help would be appreciated.

Answer
First things first.  Check your coolant levels to be sure that you have some type of engine coolant.  Next, you should probably head to a junk yard to get a new climate control module.  The thing that allows you to switch your air from hot to cold.  I think that latter is probably the solution, but email me back to let me know if it works or if we need to take a different route.
