2006 Chrysler PT CruiserHow to replace ac/heater control panel.. vacuum lines may not be in right?


Should be only one way for the vacuum harness connector to attach. Maybe the AC Heater Control Panel Diagram below will help. It looks like the vacuum line effect the re-circulation of the Air Conditioning.

  1. Remove Control Panel Bezel
  2. Remove Center Air Duct
  3. Remove the screws that secure the AC Heater Control to the instrument panel
  4. Remove the A/C-heater control from the instrument panel to gain access to the vacuum harness, control cables and wire harness at the rear of the A/C-heater control.
    NOTE: To aid in reinstallation, note the installed position of the vacuum harness prior to removal.
  5. Disconnect the vacuum harness and wire harness from the rear of the A/C-heater control (Vacuum Harness, Control Cables and Wiring Harness).
    NOTE: To aid in reinstallation, note the installed positions of the control cables prior to removal.
  6. Disconnect the control cables from the mode and temperature control levers at the rear of the A/C-heater control.
  7. Remove the A/C-heater control from the vehicle.

AC Heater Control Panel


AC Heater Control Panel Description

Both the heater-only and heater-A/C systems use a combination of, electrical, cable, and vacuum controls. These controls provide the vehicle operator with a number of setting options to help control the climate and comfort within the vehicle.

The A/C-heater control for the heater-only or the heater-A/C system is located to the right of the instrument cluster in the instrument panel. The A/C-heater control contains rotary-type knobs. There is a blower motor speed switch, mode control switch, temperature control, and airflow control.

The A/C-heater control cannot be repaired and, if faulty or damaged, it must be replaced. The control knobs and the illumination lamps are available for service replacement.

Vacuum Description

Vehicles equipped with A/C use vacuum to operate the re-circulation door. A vacuum check valve is connected to the brake booster vacuum supply. The vacuum check valve is designed to allow vacuum to flow in only one direction through the accessory vacuum supply circuits and to stabilize the vacuum within the HVAC re-circulation circuit whenever the vehicle is accelerating or engine vacuum varies due to operating conditions.

Vacuum Operation

The use of a vacuum check valve helps to maintain the system vacuum needed to retain the selected heating-A/C mode settings. The check valve will prevent the engine from bleeding down system vacuum through the intake manifold during extended heavy engine load (low engine vacuum) operation.

The vacuum check valve cannot be repaired and, if faulty or damaged, it must be replaced.

Oil Pressure Light 2008 Chrysler 300 lx 2.7

2008 Chrysler 300I have a 2008 Chrysler 300 LX 2.7. And my oil pressure light keeps coming on after I’m braking/stopped. I changed the oil and oil filter and changed the oil pressure switch and the light still keeps coming on. And while driving the oil pressure light stays off.


The next step would be to have the oil pressure checked. Your engine requires 10 psi of oil pressure per 1,000 rpm. So you need 30 psi at 3,000 rpm and 6 psi at 600 rpm. and so on.

An actual gauge will be able to show you if everything is alright.

2005 Chrysler Town and CountryMy 2005 Chrysler Town And Country’s AC Fan Motor in the front works some times. The back one always works. I am trying to find out is it more likely that the resistor is going out or the fan motor?


The AC Fan motor should be replaced. Your air conditioning system is working as it should. When the fan motor is working the different speeds work so the resistor is fine. The resistor has no moving parts so it works on all speeds or it doesn’t. If the AC fan motor only worked on High speed then I would recommend replacing the resistor. The Fan motor has internal brushes that wear and will act as you described when going out. So replacing the AC Fan Motor should fix you right up. That is after you confirm the blower motor relay is providing power to the blower motor when it isn’t working. Otherwise you will need to replace the blower motor relay. There is a separate relay for the front motor and the rear motor. When testing make sure to set the fan speed on high. This provides direct voltage with no resistance from the resistor.

2003 Chrysler Pt Cruisercar bucks when backing up


If any recent work has been performed that would be a good place to start. If any recent brake work has been performed a bolt may have been left out on a rear brake caliper, etc. It may be prevalent to place the vehicle on four jack stands and see if the car bucks when no longer on the ground. Check for anything loose in the suspension. Try to determine if it is more from the front or rear. Can you feel anything in the steering wheel, etc. when the bucking occurs?

Oil Overfilled Chrysler Concorde 1997

1997 Chrysler ConcordeEngine oil overfilled and driven, having problems now. How bad is this? And can this be fixed.


Not that bad. Much better than if it was under filled. Yes, it can be fixed. Drain the oil and refill to the correct level. Engine oil is to checked on a flat surface with the engine off.


The best time to check engine oil level is after it has sat overnight, or if the engine has been running, allow the engine to be shut off for at least 5 minutes before checking oil level.

Checking the oil while the vehicle is on level ground will improve the accuracy of the oil level reading. Add only when the level is at or below the ADD mark.


The lubrication system is a full flow filtration pressure feed type. Oil, stored in the oil pan, is taken in and discharged by a gerotor type oil pump directly coupled to the crankshaft and its pressure is regulated by a relief valve. The oil is fed through an oil filter and to the crankshaft journals from the oil gallery in the cylinder block. This gallery also feeds oil under pressure to the cylinder heads. It then flows to each cylinder head through passages to camshaft journals, the rocker shafts to the rocker arms, hydraulic lash adjusters

2005 Chrysler PacificaMy battery light came on while driving when I tried to turn my power steering had gone out. Then I got out of my car and noticed what looked like water leaking from the bottom of my car. Is it the water pump or hose?


Sounds like your serpentine belt may have come off or broken. The serpentine belt drives the water pump, alternator(battery light) and power steering pump. All of which you experienced an issue with all at the same time. Inspect the belt and the belt driven components. The water pump may have failed causing the belt to come off and also leak coolant.


Turning of the steering wheel is converted into linear (side-to-side) travel through the meshing of the helical pinion teeth with the rack teeth within the steering gear. The lateral travel pushes and pulls the tie rods to change the direction of the vehicle’s front wheels.

Power assist steering is provided by a belt driven rotary type pump. It directs fluid through power steering fluid hoses to the power steering gear where it is used to assist the driver’s turning effort.

Manual steering control of the vehicle can be maintained if power steering assist is lost. However, under this condition, steering effort is significantly increased.

2007 Chrysler PacificaHas any body had problems with transfer case or power units?


There is mention of only 2 recalls and both are emissions related and require the PCM be reprogrammed. However the transfer case (power transfer unit) appears to be a common replacement part.

1999 Chrysler 300MCan the joint for the tilt wheel be replaced or do you have to replace the steering column?


Anything is possible but at what cost. Most shops will only want to replace the entire column and rightfully so. The internal parts you are looking for are not readily available for purchase. It is possible to go to a junk yard and get another column and take it apart and put those parts into the one you already have. This would require a greater amount of time than just replacing the entire column.

steering column 1999 Chrysler 300M

The steering column used on this vehicle has been designed to be serviced as an assembly: less wiring, switches, shifter assembly, ignition park interlock, shrouds, and steering wheel, etc. Also, most steering column components can be serviced without removing the entire column from the vehicle.

Steering Column Replacement Labor Times

  • Column Shift¬† 2.5 Hours
  • Console Shift 1.9 Hours

These are labor time estimates based on the 1999 Chrysler 300M

2002 Chrysler PT CruiserIts code p0700 all the codes point to the transmission control module failing. We just replaced the Powertrain Control Module (PCM) 4 days ago. I know they are linked for sure could one cause the other to fail? Or a loose connection or something? We just think its odd we just replaced the computer module days ago now the transmission module is failing


Since the code P0700 is just and informative code, check the TCM for more codes to resolve the problem. May just be a speed sensor or something. It is possible to have a loose connection. Wouldn’t be a bad idea to check the connections at the PCM.

Code P0700 Chrysler Description

The transaxle Control Module (TCM) monitors the malfunction of sensors and actuators relating to transaxle control. When the TCM detects a malfunction with the control, a signal is send to the Powertrain Control Module (PCM) to trigger the Engine Light or Service Engine Soon light. The PCM stores the P0700 code and it means the TCM detected a malfunction with the transaxle controls.

Code P0700 Possible symptoms

– Engine Light ON (or Service Engine Soon Warning Light)
– Driveability problems
– Transmission shifting problems

2006 Chrysler PT CruiserHow can you tell if your power steering and oil pan has a oil leak in it? If they have a hole in them. It is a 2006 Chrysler PT Cruiser.


Checking your fluid levels and noting if the level is lower than normal would be an indication of fluid loss. You can top off the levels and check the level periodically to determine how great the fluid leak is. You can place a clean piece of cardboard under the vehicle where you normally park to access the general area an oil leak may be occurring. Once you have identified the general area you can look at that area closer. Something to remember would be that oil leaks do not travel uphill.
