Poor blower performance

Recommended Posts

@Honey Badger brought her truck down. The A/C and heater blower performance was poor. So i broke out the bore scope and fed it into the evaporator to see if it was plugged with debris. Screenshot_20220814-115631.jpg


I started checking the blower rotation it was wired backwards. Once I put the black to the black/tan and green to the blue/yellow it has awesome blower performance. A/C is nice and cold and blows air strong out the vents. Zero cost, no parts, just fix someone's crappy wiring.
