Getting more heat from a Chrysler Lebaron

I have a 1994 Chrysler Lebaron Convertible with a V-6 and A/C. Is there a way to increase the heater output, like changing the thermostat? It has a four speed automatic which keeps the revs low on city streets. I’ve noticed the incoming air is much warmer when the rpms are greater than 1800 but at low speeds the engine rarely gets up there. If I drive in 3rd gear the revs get up over 1800 but the fuel economy suffers. I was wondering if there was a way to increase the temperature of the incoming air.

  1. Sounds to me like you may have a small vacuum leak in the hose coming from the head control unit to the blend door(hot/cold) diaphragm.

    When the engine is at low rpms it creates less vacuum and when the rpms are up it creates more vacuum. This would cause the issue you are having.

    Thermostat is working or you wouldn’t have heat.
