SUBJECT: ELECTRONIC TOUCH CLIMATE CONTROL ASSEMBLY
MODELS AFFECTED: 1985 ELECTRA WITH C68 OPTION
New control assemblies went into production on July 11, 1984 with logic changes to assist heater and A/C performance. The following changes are incorporated in the new unit:
1. Remember blower setting if mode is changed.
2. Remember mode and blower setting for approximately 30 minutes after ignition is turned off. Approximately 30 minutes after shut down, the system will revert to auto mode/auto fan.
3. Revise blower curve so blower comes off "hi" blower sooner in heater mode.
4. Change time for temperature display to change one degree in approximately 1/2 second. Previous display change took approximately one second.
5. Changed LED indicators showing mode and blower settings to lower intensity.
Service remanufactured units with these changes can be obtained from GMWDD under part numbers:
1227047 with rear defogger option (C49) 1227048 without rear defogger option
