2004 dodge stratus heater/ac issues

sounds like you need a new blower resistor, its under the dash on pass. side. if it goes bad your blower will only work on high. its fairly easy to change

Check coolant level first, and make sure it's topped up to proper level in bottle. Let me know what you find.

I'm assuming you mean the fan only works on high. If that's the case the blower motor resistor is bad. When the fan switch is on high it puts a full 12Volts to the blower motor. When you have the switch in any other possition, the voltage is routed through the resistor and reduced thus making the motor run slower.

This is a bad blower motor for your AC and Heat. Replace the blower motor.

The area where you "hit" to make the unit go is your neighborhood for investigation.

Something is loose or not making a good connection.

If you discover that there are no loosenesses, sometimes a blower motor can get a dead spot, but typically, once going, the motor would not stop, with that condition.

The resistors are in circuit only on the lower fan speed settings.
On the highest speed setting, power is switched directly to the fan motor.
Check fan power supply fuses,
Check power is available to the fan when high speed selected.
If all above OK, apply power directly to the motor to verify fan motor runs- if it doesn't the motor may need replacement/repair.

sounds like a faulty heater resistor..located in heater box on pass side..remove a trim panel under glove box..if you get new one,you'll be able to see what it looks like..10 way connector..only has 5 wires..2 screws hold it in heater box..you may have to trim opening to fit new resistor..new part updated

you need to begin by changing the thermostat. if you dont know how go to an autozone and they will assist you.

if that doesnt solve the problem you need to change the heater/ac blower relay.

you can change the thermostat yourself for under 20 dollars. if you dont know how go to an autozone and they will assist you.

You have either lost vacuum to the mode control switch or the switch leaks, this switch is in the ac conrol head in the dash. When you select dash, floor etc. this what changes where the air comes out.
