SOURCE: How to program a keyless remote for a Pontiac

NOTE: You must have the correct part number on the remote for it to work. The part number you need is 15732803.
Transmitter programming per the GM manual:
Before entering the programming mode, verify the possession of all the transmitters you will be using on the vehicle. Once you program the transmitter, the memory erases the other transmitters. You may program up to 4 transmitters.

1. Turn OFF the ignition switch
   
2. Usa a fused jumper (3 amp is sufficient) and connect terminal 8 (back/white wire) to terminal 4 (black wire)
   
3. Close all the doors
   
4. Turn ON the ignition switch / the doors will lock
   
5. Press and hold the following buttons on one of the transmitters for 30 seconds: lock and unlock
   
6. After a 30 second delay, the doors will lock and unlock Important: 
   DO NOT turn OFF the ignition . If the switch is turned OFF the first transmitter becomes inoperative.
   
7. In order to program extra transmitters repeat Step 5
   
8. Disconnect the fused jumper wire from the data link connector
   
9.  Turn off ignition
   
10. Verify functions of all programmed transmitters.
    

SOURCE: 1997 Bonneville SSE, when the heater is turned on, only cold air

you may have a failed blend air door motor/actuator. this part will regulate the amount of air from the heater core depending on the temp setting on your electronic climate control unit. if it has failed, it will be stuck at the temp that it was last set at when it quit working. it is also possible the heater core may be plugged up, but using the gm recommended dexcool coolant and flushing it out every 5 years, it should not be plugged up. you can pull the 2 heater hoses off the heater core on the passenger side of the engine compartment firewall and see if the heater core is the problem. caution-do not use a high pressure air hose to blow through the heater core as this could damage it and cause a leak!

It maybe the control unit or just one of the wheel sensors.
