I have just bought a 2000 roadster, an upgrade from my 1994. I have two nagging things that I cannot figure out. First my key fob is not working. I have replaced the battery in the fob but it is still not working. When the car was on the showroom floor the battery in the car did die and needed to be charged. Is there a procedure that I need to go through to get the car and the key fob to link up as there was in the 1994 or do I need to go the dealer and have them link it up? And second how is it that I set the dual climate control? I am always hot and my wife cold. I am sure that both of these items are covered in the owner’s manual that did not come with the car. I am planning on getting it but figured I would try here first. Thanks a bunch, John

 

I'd go to the dealer and make them do what should have been done on delivery.

 

did you resync your fob? If you didnt, hold down the unlock and lock button for about 5 secs.

 

Probably just needs to be re-synched.

 

Yep, hold both buttons down until the horn blows, then you're good to go.

Can't help on the dual climate control thing. I've got the old fashioned kind. I do know that there's only about a 6-7 degree difference in both sides if that helps any.

 

Or here is the long GM version.

Transmitter Programming
Each transmitter has a unique Vehicle Access Code (VAC) that changes every 5 seconds. If a transmitter or receiver is replaced, each transmitter must be programmed to the vehicle's receiver. Entering a specific button sequence on the DIC, up to 3 transmitters can be programmed into the receiver. After programming the transmitters to the vehicle, the receiver will update this code every 5 seconds in order to match the code programmed in the transmitter.

The transmitter may not communicate or become out of synchronization with the receiver if any of the following situations occurs:

The transmitter battery is disconnected.
The vehicle battery is disconnected.
The transmitter and the vehicle are separated for 2 weeks or more.
The receiver is disconnected.
Perform the synchronizing procedure if the transmitter does not communicate or becomes out of synchronization with the receiver. If the transmitter and/or receiver are replaced, preform the following programming procedure:

Programming Transmitters
Turn the ignition to ON.
Turn the radio to OFF.
Press the RESET button on the driver information center (DIC) in order to clear any IPC warning messages.
Press and release the OPTIONS button on the DIC to scroll through the display options until the IPC display is blank.
Press and hold the RESET button for 3 seconds.
Press the OPTIONS button until FOB TRAINING message is displayed.

Important
If the FOB TRAINING message cannot be display, check if the BCM is configured with the correct RPO codes.


Press the RESET button in order to begin the programming sequence. The message HOLD LK + UNLK 1ST FOB will be displayed.
Simultaneously press and hold the LOCK and UNLOCK buttons on the first transmitter for 15 seconds. The IPC will indicate when that transmitter is programmed and when to proceed to the next. Repeat this procedure for each additional transmitter or press the OPTIONS button to exit.
Programming Cancellation
The receiver will cancel the programming sequence if any of the following conditions occur:

The program mode is exited through the DIC.
The ignition is turned to OFF.
The three transmitters have been programmed.
The RFA system has been in the program mode for longer than 2 minutes and no transmitters have been learned.
If the program mode is cancelled with less than 3 codes stored, the receiver will only accept the codes just stored. If the program mode is cancelled before any code is stored, the codes still remain valid.

The receiver retains all current access codes in memory if either of the following conditions occur:

A programming sequence is interrupted.
The battery is disconnected.
Synchronizing Transmitters
Preform the following procedure if a transmitter cannot communicate or becomes out of synchronization with the receiver:

Move a programmed transmitter within range.
Press the LOCK and UNLOCK buttons on the transmitter simultaneously for 7 seconds.
The horn will chirp once when the transmitter is synchronized. Repeat this procedure for each additional transmitter if needed.

Oh and if you aren't confused after reading the GM description....

Operating Modes
The driver can select from eight different modes of operation from the heater and the A/C control head. The HVAC can initiate two additional "purge" modes when certain conditions exist.

Off
Select the off mode to turn off the blower motor and the A/C compressor. The control head displays the SET TEMP information for 5 seconds, then reverts to the OUTSIDE TEMP display.

While the vehicle is moving, some air is forced into the vehicle through the air intake. This air is delivered through the HVAC module and out of the Heater and Defrost ducts.

When the A/C compressor is off, the air temperature can still be adjusted. The air can be warmed, but not cooled.

Auto
In the auto mode the control head turns on the system power. The system tries to obtain the last temperature setting and the system tries to maintain that setting. The system changes the air delivery mode to automatic and the system illuminates the AUTO and AIR DELIVERY mode graphics.

The blower speed adjusts automatically as the system nears the temperature setting. The blower speed changes by pushing the blower speed button up or down. The control head displays the SET TEMP information for 5 seconds. Then the control head reverts to the OUTSIDE TEMP display and illuminates the air delivery mode graphics.

Mode
Press the MODE button to manually lock in the current air delivery setting and to stop the automatic mode control. Pressing the MODE button will delete AUTO from the digital display and the MODE graphics will be shown.

When the mode button is pushed, the control head cycles through the manual air delivery modes in the following sequence:

UPPER
LOWER
DEFOG
BILEVEL
Recirc
Press this button to limit the amount of fresh air entering the vehicle. The light on the button will come on to show that the system is operating. Recirc is helpful when you are trying to cool the air quickly or trying to limit odors and just from entering the vehicle. When the system is in the AUTO mode, the system automatically selects Recirc to cool the vehicle's temperature. By pressing this button , the system will lock into the recirculated air mode. Any adjustment to the air intake must then be made manually. The Recirc mode will not operate in the front defrost mode, this helps prevent windshield and window fogging due to moisture in the vehicle.

The recirc mode function operates in the following air delivery modes:

UPPER
LOWER
DEFOG
BILEVEL
Upper




This setting directs most of the air through the instrument panel outlets and a very small amount to the lower outlets.

Bi-Level




This setting directs air into the vehicle in two ways. Cooler air is directed toward the upper body through the instrument panel outlets, while warmer air is directed through the lower outlets.

Defog




This setting divides the air between the windshield and lower outlets and a small amount toward the side window vents. This is useful if fog appears on the windshield or side glass due to rain or snowy conditions.

Front Defrost




Press the FRONT defrost button to quickly remove fog or frost from the windshield. This setting directs most of the air flow to the windshield and a small amount toward the lower and side window outlets. The light on the button will come on and the digital display will show the defrost mode symbol an fan speed when the front mode is being used. Pressing FRONT defrost again will return the system to the last operating mode.

If the system is in FRONT defrost when the engine is shut off, it will restart in FRONT defrost unless the engine is off for longer than 40 minutes. If the engine is off longer than 40 minutes, the system will restart in the operating mode that was set prior to FRONT defrost.

Rear Defrost
This button turns the rear defogger and heated outside mirrors on. The light on the button will come on when operating. The system automatically shuts off after approximately 10 minutes. If further defogging is desired, press the button again.

A/C
This button turns the air conditioning compressor on or off, except in the FRONT defrost mode. The light on the A/C button will come on when the compressor is operating in either the automatic or manual mode. The air conditioning may be forced off at high engine speeds. The light on the A/C button will flash if pressed when the air conditioning is not allowed to operate.

The air conditioning does not operate at temperatures below approximately 2°C to 4°C ( 35°F to 40°F). If the system is operating in the AUTO mode, turning the air conditioning off will delete AUTO from the digital display and show the current mode and fan settings. The AUTO button must be pressed to return to the automatic mode operation.

Outside Air (OSA)
Press this button to provide fresh air from the outside. The light on the button will come on to show that it is operating. When in the AUTO mode, the system automatically selects outside air to control the temperature in the vehicle. By pressing OSA button, the system will lock into the fresh air mode. Any adjustment to the air intake must then be made manually. OSA should be used when trying to defrost or defog the windows to help reduce moisture inside the vehicle.
