2004chrysler pacifica, the engine light flashes10 times with key in on. I know it's a code but I don't know which or have a guid to look it up with. Can anyone tell me what code it's flashing? Please!

Weak battery- Low voltage while cranking
- Faulty Engine Control Module (ECM) relay
- Blown ECM fuse
- Faulty ECM
- ECM harness is open or shorted
- ECM circuit poor electrical connection

that is the check engine light
if you turn the key from off to on 3 times in the trip meter it should display a code that starts with P
if you type the code in google or post it here it will tell you what is wrong

the blower motor control module could have an electrical contact that expands when it warms up and then works.
It is behind the glovebox, the connector that goes to the motor is 2 wires, the other connector goes to the control head. The dark green wire in that 2 wire connector is positive power to the blower motor, the black is ground. If it will power a test light, then it is probably the motor. If has no power out, then it is probably faulty.
The module is a common repair

You should have the computer scanned for trouble codes first. The codes may point you in the right direction to look for the problem.
Common causes for stalling is a dirty throttle body or faulty idle air control valve among other things.
Let me know what the codes are.

Your fuel pump assembly needs to be replaced fuel level sending unit bad.

No it doesn't

Codes don't tell you anything is bad

They are used to diagnose & component test
a sensor or other parts of a system

You only replace a part if it fails a test

If your not testing the system & it's components,
how would you know what does work & what doesn't?

P0300
1.ignition system fault spark plug ign wire coil.
2.vacuum leak, inj fault.
3.high or low fuel pressure.
P0420
1.catylist eff low bank1- cat can be defective.
2.eng misfire, vacuum leak.
3.engine oil leak into the exhaust valve guide seals.
as for the warranty i dont know.

my dash lights stay on after i turn off my van, the fan stays on also the alarm does not work or the keyless entry does not work.

If the light isn't flashing, it is safe to drive. If it is flashing, then catalytic converter damage can result. Have a parts store check the codes for you and come back and post the code.
