Question about 1999 Chrysler 300M
Chysler = electrical problems. If you have digital readout for setting your temp. run it all the way up then all the way down, then hold hand over vent while runnig it back up. STOP when you feel air getting hot. Fix take out control unit and clean all connecting tips and put back. get a manual so you don't tear up more than you fix.
Also they have problem with heater control valve. With motor hot make sure both heater hoses located behind eng close to center are hot to touch. If not control valve is problem. Bill

Code 23= Blend door feedback control
On cars with automatic climate control: To enter diagnostic mode, set the temperature to 75F, press the the off button. Press Floor, Defrost\Floor, Front Defrost simutaneously for 3 seconds until the temperature display begins to flash.
On cars without automatic climate control, set the blower to any speed, turn the temperature control in between warm and cold. Press Floor, Defrost\Floor, and Front Defrost. All codes will flash via the Front Defrost button.
When the test is over all fault codes will be displayed (on cars without automatic climate control, they will be blinked out on the Front Defrost button).

SOURCE: The car cranks but won't start
Ok, check the following below--
1. Check the Ignition control Module for its operational value. it may be damaged.
2. Check the coils.
3. Check the plugs and wires.
4. Check the ECM/PCM/ECU(All represent the same device that is commonly known as the engine control computer)
Check these areas thoroughly for faults. I would also advise to replace the fuel filter and fuel pump as well.

yes they are the same transmission outside and have the same disignation of 42LE, but they may be different gear ratio's, they have tags on them that can id the internal differences, the 300 uses a 3.5 liter, which is not avail in the Conord
