My battery just died on my 2004 Chevy Avalanche. After replaced the battery, the heat on the drivers side doesn't blow as hot as on the passanger side. When I have both sides cranked to max, only the passanger side blowers hot, the driver side blowers warm. Any thoughts on how to fix this? Is there a was to reset the heater or something??
1. Place the ignition switch in the off position.
2. Remove the HVAC/ECAS fuse for 10 seconds or more. It's in the under hood fuse box. Put the temp in full cold.
3. Install the fuse.
4. Start the engine. DO NOT TOUCH THE HVAC CONTROLS FOR LESS THAN 45 SECONDS.
5. Have any codes cleared with a scan tool.
