Question about 1999 Dodge Intrepid

1 Answer

Heater AC blower only runs on high. I've checked all related fuses that I know of. Is there a connection to a multi-resistor somewhere that needs to be checked? Thanks for your help.

Repair temp control


First. Check all the fuses-focus on the blower motor fuse. The fuse box is located near the hood release lever.
Make sure the slide levers controlling air direction and heat are at the top position. Make sure that the blower switch is on high.
Carefully pull temp control unit out about 2 inches, by removing 2 screws at bottom of unit. Get a test light, and check for current to the unit and blower motor.Make sure the connections to the switches are good.
Check the resistor connection to the blower motor. It is in the engine compartment on the AC condenser housing- at the firewall.
Check all the connections related to the blower motor and make sure there is current to the unit.
A test light will help determine what is at fault. If it is a switch behind the control unit, replace the whole unit. Your local auto salvage yard could have one.
Good luck.

Why would front console blower fan only work on high?


There is a resistor somewhere that cuts the voltage down for slower speeds. High speed runs on a direct circuit.
You need to find that resistor - - may need a shop manual.

Inside fan switch has 4 speeds only high works,


I have great news!It is not that bad!Look near the blower motor in the blower case housing ther is a blower resistor.It will have a multi-wire plug in.Unplug this ,and remove the two screws that retain the resistor in the box.Pull the resistor out ward,it will be out.The part store will have it or can get it for you.This is your speeds for your blower motor.If the blower is making any kind of racket,or seems to be slow when it is on high selection,replace it also,cause this is the cause if the resistor going out.

Heat/ac blower motor works on high. intermittent on other speeds.


Check the blower resistor pack - usually located in the heater air ducting in the blower fan airflow. Check for loose connections and open circuit resistors on the unit.
If speed 4 works always, its unlikely to be the blower motor ground connection.

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.

Hi, sounds like your blower motor resistor needs to be replaced. If not the resistor, check the blower motor.

Heater Control Switch Only Works on High


It appears there is a resistor block there, either at blower connection area, or at firewall area on passenger side under cowl somewhere. It is quite common for blower to only work on high when resistor goes. Look for block, or base, 1-1/2" x 3" approx. with electrical connector to it.
