98 Dodge Intrepid Blower stuck on high and no display.
98 Dodge Intrepid, with the automatic climate control option (only one knob for fan speed the rest are buttons with a digital readout). Recently the display died and the fan speed is stuck on high, I am not sure if both happened together or not. Does this car have a separate blower motor resistor or just the one electronic unit on the dash. I am getting different answers depending on who I ask. Thanks

If the blower motor only works on high mode, then its problem with blower motor resistor.
The blower motor resistor needs to be replaced.This will make blower motor work on all modes.
I replaced the fan module under the glovebox on my 2005 Town & Country last night. Mine would not shut off at all with key on. It only blew on high no matter where I set the switch. Mine also had the climate control which makes a difference. If it is not the auto climate control it is usually the blower resistor if the other fan speed selections don't blow at all except on high.
Might be the same....You may want to do the diagnosis proceedure. Alot of times its the door actuators. Servos in replace of old cable design. Usually it will be a code 46. DOOR BLEND ACTUATOR SHORT TO BATTERY. The DTC's can be checked with the MTC control and the Odometer
Display of the Mechanical Instrument Cluster if a DRBIII® scan tool is
not available. The MTC control can only be placed into the diagnostic
mode while the engine is running and the vehicle is not moving. To place
the system into it's diagnostic mode, adjust the MTC control to the
The engine must be running with vehicle not moving.
The fan speed set to any speed except OFF.
The temperature control knob in full cold (full counterclockwise position).
The mode control knob must be placed in Defrost position (full clockwise position).
The A/C button can be On or Off.
and hold the rear window defogger (EBL) button until the mechanical
instrument cluster odometer display indicates an "AC00". The BCM will
chime once and the MTC A/C button LED will begin blinking.
the EBL button and wait until the MTC A/C button LED stops blinking.
This means that the error check and climate control door calibration is
complete. NOTE:It is important that no
other control knob or button is pushed until all DTC's are read. Pushing
any button except the A/C button or turning a control knob will end the
diagnostic test without showing the rest of the DTC's. There also may
be other DTC's stored in the BCM not related to the climate control
system. These DTC's can only be found using the DRBIII® scan tool. DTC's
related to the MTC control head will appear on the odometer display in
numerical form after the letters "AC". The odometer display will return
to normal operation if no DTC's are found. If a problem is found, then
the odometer will display the letters "A/C" followed by the DTC number.
The odometer display can only show one DTC at a time. Under certain
circumstances, more than one DTC could be in the memory. To scroll
through any additional DTC's, press the A/C button on the MTC control.
The BCM will beep each time the A/C button is pushed. Continue pushing
the A/C button and recording the DTC's until the odometer returns to
normal operation (note the letters AC will dissapear.
According to the schematics on your vehicle, it has a "Blower motor control processor" either built in to your controls, or in line between your controls and blower motor. Yo may get real lucky and find some dirty connections in that area, and get away with cleaning & re-connecting, but I wouldn't get my hopes up too high. You may end up replacing the processor, as it regulates fan/blower speed.
