Subject: | HVAC Operation During Remote Vehicle Start (RVS) |
Models: | 2008 Pontiac G8 |
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Operation of HVAC system during RVS.
Remote start is standard on all G8s for 2008.
Note: While the remote start will interface with the "automatic" HVAC system to turn on the heating or cooling to achieve a temperature of 73°F (23°C) and activate the rear window defogger, it will NOT interface with the manual HVAC system. Therefore, vehicles with manual HVAC controls will not have any heating or cooling activity inside the cabin during a remote start event.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
