1997 03 Buick Regal climate control display repair part 3

The most common cause is a faulty blend door actuator.

Hello David,

Could be climate control module, body control module, various actuators, or a variety of other issues.

Have you tried discussing with a local certified mechanic?
You can try downloading technical manuals here:
Haynes Manuals

normally the climate control unit itself which is part of the display panel inside

the fan speed control not adjusting usually means the 'resister' is no longer working. Stuck on cold means the 'blend door actuator' is no longer functioning.

I had a similar problem with my 2003 intrepid. The problem turned out to be the control panel. I went to a salvage yard and got one.

locate the fuse from the fuse box and replace it with exact fuse. it would help

Climate control is turned on by pressing the 'auto/econ' button.
There will be a temperature control for it that lights up on the right hand side of console display. One can also control the fan speed there or leave it on 'auto'

It way be a bad or dirty climate control sensor.

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 following settings:

1. The engine must be running with vehicle not moving.
2. The fan speed set to any speed except OFF.
3. The temperature control knob in full cold (full counterclockwise position).
4. The mode control knob must be placed in Defrost position (full clockwise position).
5. The A/C button can be On or Off.
6. Press 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.
7. Release 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.
