The shift lever where you adjust where the heat needs to go may be the problem. It's mechanical, and if it functions except defrost, then it sounds more like a mechanical problem w/ the heat adjustment. Unless you aren't getting heat at all.

I replaced air blend actuator and the air is still blowing out front vents only wont go to floor or dash


The blend actuator/door does not control where the air goes, it only controls how much of the air coming in is routed through the ac evaporator and/or heater core. You didn't state year, make, or model, but most cars have two or three more acutators for controlling inside/outside air, floor/dashboard outlets, and defrost.

How do I remove the center console where the heater control switches are located on a 2006 Pt Cruiser GT


DESCRIPTION A manual temperature control (MTC) single zone type heating-A/C system or a manually controlled heater-only system is standard equipment on this model, depending on market.
To maintain the performance level of the heating, ventilation and air conditioning (HVAC) system, the engine cooling system must be properly maintained. The use of a bug screen is not recommended. Any obstructions in front of the radiator or A/C condenser will reduce the performance of the A/C and engine cooling systems.
The engine cooling system includes the radiator, thermostat, radiator hoses and the engine coolant pump. Refer to 7 - Cooling for more information before opening or attempting any service to the engine cooling system.

All vehicles are equipped with a common heater, ventilation and air conditioning (HVAC) housing (1). The heating-A/C system combines heating, ventilating and A/C (if equipped) capabilities in a single HVAC housing mounted within the passenger compartment beneath the instrument panel. The HVAC housing includes:
  1. Mode-air doors (2)
  2. A/C evaporator (A/C system only) (3)
  3. Recirculation-air door and actuator (A/C system only) (4)
  4. Blower motor (5)
  5. Mode control cable (6)
  6. Temperature control cable (7)
  7. Heater core (8)
  8. Blend-air door (9)
On heater-only systems, the A/C evaporator is omitted from the HVAC housing and is replaced with an air restrictor plate.
Based upon the system mode selected, conditioned air can exit the standard heater-only or optional heater-A/C housing through one or a combination of the three main housing outlets: defrost, panel or floor. The defrost and panel outlets are located on the top of the HVAC air distribution housing and the floor outlets are located on each side of the distribution housing. Once the conditioned air exits the HVAC housing, it is further directed through molded plastic ducts to the various outlets within the vehicle interior. These outlets and their locations are as follows:
  1. Defroster Outlet- A single large defroster outlet is located in the center of the instrument panel top cover, near the base of the windshield.
  2. Side Window Demister Outlets- There are two side window demister outlets, one is located at each outboard end of the instrument panel top cover, near the belt line at the A-pillars.
  3. Panel Outlets- There are four panel outlets in the instrument panel, one located near each outboard end of the instrument panel facing the rear of the vehicle and two located near the top of the instrument panel center bezel.
  4. Front Floor Outlets- There are two front floor outlets, one located on each side of the center tunnel near the dash panel.
  5. Rear Floor Outlets- There are two rear floor outlets, one located on each side of the floor panel center tunnel near the front of each rear seat foot well.
  6. REMOVAL
    WARNING: Disable the airbag system before attempting any steering wheel, steering column, or instrument panel component diagnosis or service. Disconnect and isolate the negative battery (ground) cable, then wait two minutes for the airbag system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the airbag system. Failure to follow these instructions may result in accidental airbag deployment and possible serious or fatal injury.


    NOTE: Illustration shown with instrument panel removed for clarity. (Refer to 23 - Body/Instrument Panel/BEZEL, Instrument Panel - Removal).(Refer to 24 - Heating and Air Conditioning/Controls/CONTROL, A/C and Heater - Removal).(Refer to 23 - Body/Instrument Panel/COVER, Steering Column Opening - Removal). 5. Remove the screw (1) that secures the temperature control cable (2) to the left side of the HVAC air distribution housing (3). 6. Disconnect the temperature control cable from the blend door pivot lever (4) and remove the cable from the vehicle.

How do Iclean and flush the coolant line


Remove the outlet and inlet hoses from the heater core and hook up a hose to back flush the core through the outlet tube. The return outlet tube is usually the smaller hose.

A/c flow


A: Cable has come off door on defroster.

B: Fuse is blown on that part of wiring. May or may not be listed under A/C; could also be under heater.

C: I believe 96 models still had some inline fuses in the wires. Wouldn't hurt to check.
