Why does the fan in the car work on 4 and not 1-3 on a dodge 2004 stratus es?

Question

The fan for the air and heating in the car does not work on settings 1-3. Is there something I can check before I take it to a repair shop?

Answer 1

your problem lies in the fan reostat replace it with a part from the dealer and problem will be solved one of the above answers is incorrect ! there is a relay for high speed fan operation and the reostat controlls lower speed's of the blower motor the reostat is located in the hvac unit right next to the blower motor on the passenger side of the veh, it is rectangular in shape with like a 8 way electrical connector

Answer 2

the comprehensive heater/A/C blower motor unit is administered by a administration module or module that makes use of a definite severe amp resistor that's talked approximately as the ballast resistor.many times if this is that resistor each and all of the different administration ranges will finally end up being like the no4 point comprehensive blast or the blower motor does not come on.additionally the change ought to be defective on it that ought to reason in basic terms one point or placing to artwork, plus if it isn't the change this is in all probability the module that's inflicting that difficulty. desire that facilitates and better of success.by the way the faster fashions or different sidestep fashions or years ought to apply an identical module or blower assemblies and the U %. vehicle wreckers ought to tell you what fashions etc use an identical factors.word I'am uncertain precisely on that kind how the blower motor windings are designed etc even though it is not impossible each and every so often for a blower motor to be defective internally and reason such matters.

Answer 3

It's more than likely the fan switch. In positions 1 thru 3 there is a resistor in series to control the fan speed, position #4 is basicly a direct connection to the battery, a full 12 volts applied to the fan motor. To find out for sure, remove the switch an put an ohm meter to it. I bet you'll find out that the switch is open in the first 3 positions.
If that's the case you can replace the switch, and likely fix your problem. (try a junkyard first, before a parts store to save big money on a replacement switch.)

Answer 4

Check all the fuses and relays that are in the boxes first. If you have an owners manual it will show where they are and which fuse or relay services which circuit. I know that some years of Chrysler products have one fuse for the 1-3 speeds and a heavier fuse for the highest speed. The fuses are the least expensive fix and you might be able to solve it yourself. If that doesn' t do you are headed to the dealer.

Best of luck

Answer 5

I agree with al I have seen this problem many times On chevy and dodge your blower motor resistor is bad Find your fan motor and look around it for a rectangular shaped plastic plate with a connector going in it , that would be your problem

Answer 6

there,s a relay for the fan,,i don't know where it is located ,,but it what cause this,,i own of these cars,,and right before i got it,,they said that they had replaced the relay,,i think it is in the passengers side kick panel,,when you remove it,,you,ll see some relays there,,i also noticed there are a row of them out in under the hood,,if there is a cover on them,,one of them will be ,marked heater relay ,,this will be the one you want,,i have heard they go bad a lot,,but have not had to replace mine again,,but only time will tell,,i hope this help,s.

Answer 7

The fan switch is bad. When you turn the switch on and off, low to high, do it slowly. The switch is in the $15 range, the labor is in the $100 range

Answer 8

not sure where these people get their info but the blower resistor is bad go to your local dealer or parts house and get one..
