In most cases, the drive must be at various speeds, including stop and go, the engine must reach operating temp of 195 degrees, and the vehicle needs to be driven at least 25 miles at highway speed.
Some models require other various steps to complete the cycle.

It could be a weak pump. It could be pretty old if you haven't changed it recently. To be sure, have the fuel pressure checked. Filters don't usually clog up and then start flowing again; once done, they're done.

If it's not up under dash cover by drivers left leg, check under hood for "Power distribution box."

Remove the front number. Ou will see it riveted to the bumper frame of the drivers side. If you remove the screws that holt the top of the bumper to the upper radiator cover and gently pull back on the grill part of the bumper you will see it.

1st thing to check is the coolant level. I've seen cars w/ no heat, or very little quite a few times caused by low level in cooling system--not low enough to overheat the engine, but enough that circulation of coolant to heater core is affected (no or little hot coolant circulation to heater core=no or little heat),
Is the engine temp gauge in the normal range? If it's in the low range, engine not reaching operating temp. it could be caused by a thermostat stuck in the open position (or no thermostat, sometimes people remove them when their car overheats, and this should not be done).
Here's how the system works: the heater 'box' contains a heater core (a mini radiator) w/ a fan and hoses connecting the heater core to the engine cooling system. Hot engine coolant is circulated thru the heater core. When u activate the heat switch on the dash, a flap door opens to expose the heater box to the passenger compartment. The fan switch on the dash activates the fan, which blows air thru the core, which heats the air.
So, if it's not the coolant level at the radiator, the fan is obviously working, the engine is reaching operating temperature, I would say it must be the flap door that opens, isn't opening fully, or isn't staying open. It could be the dash switch is defective (not supplying current to open flap door) or less likely the flap door is binding somehow. Hope it's as simple as correcting coolant level, if not, the dash switch control should be checked

a drive cycle is very complicated and is outlined in the factory emission manual, but here is the short version, u need to do about 20 miles of mixed driving, freeway steady speed, then stop and go and steady low speed, repeated idle times and stop and go, so just drive it in town and on the freeway for a few days and I am sure it will clear the drive cycle test and be ready to pass emission test.

Is there perhaps a problem with the dome light switch on the lift gate? Close all the doors, open only the lift gate and find the switch on the lift gate frame (usually a rubber covered "bump") and press it in. You might have a loose wire shorting against the bodywork or the door is not depressing the switch properly.

Head light relay.Under hood in the black box.

2004 Dodge... | Answered on Feb 17, 2013


check the relays.

Usually it's the brakes that need adjusting. As the breakes wear it makes the fill of the break lever seem out of adjustment. Check the brakes on the rear first. then if there are good the adjustment is a wire cable underneath the car. Also the cables tend to rust solid and not work on one or both the rear wheels. If so replace cable.You have just opened a flurry of tests now.

Lets start at the beginning.
You changed the crank sensor because the engine does not start ?
Do you have spark to the plugs ?
Do you have power to the coil ?
Is it a 4 cyl or V6 engine ?

2004 Dodge... | Answered on Feb 01, 2013


it could be either the forward control modual or the fuse box under the hood.
