Top 10 2004 Chrysler Pacifica Questions & Answers

Hello and Hope this helps you and anyone else experiencing this... My Wife and I have a 2005 Pac Trng and ever since we got the vehicle we had been hearing an increasingly loud "thump" on acceleration or over bumpy roads, and a loud "thunk" when initially applying the brake, also, from a high speed slow down, the car would shake in the front end. After 3 service stops at different dealers in the area (all of whom said they could not tell what it was or did not hear anything even when it was audibly noticeable, to "we think it might be the struts" explanation), I decided to do some googling on my own and found an obscure post about a little known issue with the "Lower Front Control Arms". There is a TSB (Technical Service Bulletin on this item as well - Chrysler Pacifica 2004-2005, Service Bulletin #: 0200704 and NHTSA #: 10010533). It seems that even the Chrysler Service Technicians are unaware of this issue which shocks me - Aren't they they ones who should be telling me what it is???!!! We scheduled a service check at the same dealer who didn't hear anything the first time, asked for the manager to take a test drive with me so he could hear what I was hearing, let him drive it on his own, and insisted that he look up the TSB. Since it was covered under warranty, I asked him to "please replace the item we are referring to" - I mean what else do we have to lose? They reluctantly took the car in and the manager called me the next day to tell me that I was exactly right! The Rear Lower Control Arm Bushing was extremely bad. We also had the Front and Rear Motor Mounts replaced to elimante a secondary knocking issue we experienced while accelerating. The overall effect was a much smoother (and Quieter!) take off and stop, with no popping, creaking, or "loose parts" sounds coming from the front end at all! If you are experiencing the "Thumping" or "Knocking" noises during braking or acceleration, or a slow speed "Rumble" (between 5 and 15 mph) in the front end when going over uneven ground or potholes, then you may want to have your dealership or mechanic take a look at these two items (Lower Control Arm Bushings and Motor Mounts). It has nothing to do with Brakes or Struts - unless you have a really crappy mechanic who just tinkered around with those items recently.

the dvd on a 2004 chrysler pacifica doesnt start you can hear the sound but no picture. what could be the problem?

1. Disconnect and isolate the negative battery cable.
2. Remove the passenger side cowl trim panel. See: Body and Frame\Interior Moulding / Trim\Trim Panel\Service and Repair\Cowl Trim
3. Pull back the carpet to access the front upper screw that secures the air inlet housing.
4. Remove the recirculation door actuator.
5. Remove the recirculation door actuator wire lead from the routing clip located on the lower air inlet housing and position the wire lead aside.
6. Disconnect the blower motor wire lead connector from the blower motor resistor or power module, depending on application.

Lower Air Inlet Housing

1. Remove the one screw (from the top) that secures the lower air inlet housing to the upper air inlet housing.
2. Remove the four screws (from the bottom) that secure the lower air inlet housing to the upper air inlet housing and remove the lower HVAC housing.

Blower Motor Wire Lead Grommet

1. Push the rubber blower motor wire lead grommet through the opening in the lower air inlet housing.
2. Feed the blower motor wire lead through the opening in the lower air inlet housing and remove the lower air inlet housing from the vehicle.
3. Position the recirculation-air door as necessary to access and remove the three screws that secure the blower motor to the lower half of the HVAC housing.
4. Gently flex the recirculation air door far down enough to remove the blower motor and wheel from the HVAC housing.

Blower Motor Mounting Tabs

1. Remove the blower motor and wheel from the HVAC housing. Note the position of the blower motor mounting tabs.

INSTALLATION

1. Position the blower motor and wheel to the lower half of the HVAC housing. Align the blower motor mounting tabs to the correct location on the HVAC housing.
2. Gently flex the recirculation-air door far down enough to install the blower motor and

The problem will get worse, to the point that it will leave you stranded, out of gas. The solution is simple but most dealers don't catch it. They try fuel pumps, computer updates, sensors and the problem persists. You can fix this problem yourself and without spending a nickel. Want to know how I know? I've owned two Pacifica's and both have done this. Here's why: The Pacifica has a very unique and poorly designed fuel storage system. It uses what is refered to as a saddle tank. This is so they can use the same tank in both the all wheel drive and the front wheel drive versions. If you look underneath you will see it actually looks like two tanks. The driver side is the fill side and the passenger side is the delivery side. There are actually two fuel pumps, a main pump (pumps gas to the engine) and a equalization pump (pumps fuel from the the fill side to the delivery side of the saddle tank. The problem that you are experiencing carries with it several symptoms; running out of gas when the tank is half full, the gas gauge dropping suddenly at half full, and the inability to pump more gas into the tank without shaking the car back and forth and/or pumping very slowly. This is because of the way the two sending units inside the tank send their signals to the gas gauge and the fact that only when the fill side of the tank is 100% full, can some of the gas flow over the top of the hump to the delivery side tank. You can replace pumps all day long and most likely still have the problem. So what's the fix? It's simple. Underneath the vehicle, inline with the emissions lines going to the gas tank, about middle of the vehicle, there is a small plastic air inlet filter about the size of 50 cent piece mounted to the floor of the vehicle. It is responsible for venting the tanks pressure, allowing fuel to flow into the delivery side tank. It get's full of dirt and debris. Replace it a cost of about $3.50 or just blow it out with compressed air. If you don't want to do it yourself, help those dealers out - point them in the right direction, or else they will be running in circles trying to fix the problem. NOTE: this is only a problem on Pacifica's, not other vehicles. More info on this issue here; http://www.dodgeboard.com/forums/index.php?threads/my-crazy-gas-gauge.6381/

You said it won't start but you didn't say if it will not crank. But I'm going to assume you meant it will not crank your turn over. And that case tests for power at the solenoid it will probably be on the starter or some were on the cable going to the starter and the battery. Using a test light check for power at the small wire at the solenoid while you have someone turn the key to start. If you do not have power here you may have a problem with your ignition switch, antitheft system or blown fuse. If you do have power here, you might have a bad connection, bad solenoid, or battery problem. Good luck.

There are some possibilities which you will have to check in this case:--
1) First of all check the power and voltage to the battery. With meter it will show exact 12 volt if the battery is charged. If the voltage is less get the battery charged at local auto repair shop. If the battery is internally drained and not getting charged then its time to replace the battery.
2) When you crank the car do you see spark coming at the spark plug? If no then its time to check the spark plugs and coil pack. If the spark plugs are not worn out and looks new then its time to check coil pack. The spark plug gets power to spark from coil pack.
3) The other thing to check in this case is the starter solenoid of the car. If the battery is charged and you start the car then it gives power to the starter to start the car. But if starter is faulty or not connected properly then car will not start.
4) The other thing to check in this case is fuel in the car. If there is fuel in the car then check the blockages in the fuel pump if the fuel pump looks proper then check the fuel filter above the fuel pump.
5) If all the above possibilities mentioned above checked out OK/perfect then it’s a electrical issue and the wiring's in the car needs to be checked. The car gets power from the battery to get started. so the wires from battery needs to be checked one by one.
Thanks. keep updated for any more query.you can rate this solution and show your appreciation.

How do I reset anti theft for an 05 chrysler pacifica so I can start car

I have a 2007 chrysler Pacifica and it had the same problem. It would crank over but not start. Took some time to figure out but in the end the asd control wire that runs from the fuse box to the PCM was corroded in half about 5 inches from the fuse box. It would show 9 volts at the PCM but no continuity.
