20 Most Recent 2004 Chrysler Pacifica Questions & Answers

The overflow tank or radiator cap may not be holding the coolant under pressure. Try replacing the cap which would be cheaper than ant other fix.

Usally when a blower motor resistor goes bad the fan still runs on high. The resistor lowers the voltage going to the fan to make it run slower. The high setting usually goes straight thru. Resistors are usually easy to get to, under good on the firewall or under dash passenger side. Cost about $24 at parts store. Replace with new if that doesn't work return it.

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/

Should be clear that the problem is in the steering column horn mechanism, but to fix it you will need to remove the air bag.. Are you competent to do that safely?

start at the battery terminals-- loose check ground wire to engine check fusible links and ING fuse you have lost connection to the battery

Hello. It seems that belt tensioner is either 'weak' or the serpentine belt is not turning 'true'. Also, if the harmonic balancer is NOT 'fully' seated on the crankshaft, the belt will turn not 'true'. Usually if the belt tensioner if not strong, it will make a 'squeaking' sound. Good luck and keep me informed; if you want to.

You need a DRBlll(R) Scan tool. Go to dealer or lock smith. If you had both keys you could do it yourself up to eight keys

An auto parts supplier might have one.

Is this the original battery? Have u had it tested? The no crank, clicking noise is classic dead battery symptoms, lights can still work, but not enough power to turn engine over. If it's the original battery, it's at the end of it's life cycle, and should be replaced. U can get the battery tested for free at any parts store.

its located near the battery , generally inside front bumper driver side

The lid of the fuse box identifies which fuse or relay sits. A diagram should say ABS 'something'. Hope this helps

We have the same problem, the ground wire from the battery is too small of a gauge. Replace it and it should be fine, get a size up gauge or you can use the same but expect it to happen again within a year when it corrodes again. It's a common defect in this model.

My personal suggestion would be to go for these repair catalogs. I know this website www.reliable-store.com that i used to get manuals from, and they have all models online. I also brought for my 1989 BMW, such old model, they had it and it was very good manual. Go ahead, I bet.
