I don’t have a hvac/ecas fuse under the hood on my 2003 trail blaser only a fuse marked ecas that is a 30 amp fuse and a 10 amp fuse marked ac and a large square fuse marked ac but doesn’t have any amps denoted for it in the scymatic. Would there be any fuses that I would need to remove in the fuse box under the rear seat behind the drivers seat?


Yes, the fuse you will need to remove for recalibration is the HVAC B fuse in the rear fuse box.
