What would make your 1998 Dodge Ram 1500 AC to change from blowing out the front vents to blowing out the defrost vents upon acceleration?
you have a vacume leak probbly going to the heater control There is a check valve that prevents the loss of vacuum to the heater controls. This check valve goes bad. Then, as you accelerate, the vac. in your engine drops and along with it, the vac to the heater controls drops (is less). To fix this, locate the check valve and replace it. Follow the vacuum line from your firewall (where it goes through the fire wall) back to the check valve. This check valve may be located between the engine and a vacuum reserve tank. The heater controls may be using the vacuum from the reserve tank. In any case, find the little check valve in the vacuum lines and replace it. You will see a remarkable change in the heater controls. I hope I explained this well enough. See you Later, Check your intake gasket if it is leaking at all it will cause it.
