Hey, so I wanted to upgrade my fan blower motor since it starting squealing, only works on high (I gotta change the resistor still), and the air it pushes out of the vents on high is terribly low (and yes I’ve done just about every other thing mentioned in other threads to “fix” poor airflow).
So my question is, does anyone know the voltage/amps of a gmt400 and a gmt800/900 blower motor? And possibly of the resistors? I don’t know much about electrical and don’t want to burn my Yukon down haha.
I just finished cutting up my hvac box where the blower motor sits to fit a gmt800/900 blower motor and it seems to push more air through the vents (it’s done but not done well haha, the section where the blower motor sits is removable but I cracked and broke some of the plastic since I didn’t know the best way to remove it at the time so a lot of air was coming out behind the dashboard when I tested it, so I will get another one for my final assembly, and will have to find a way to properly secure the blower motor to the hvac box since the blower motor I got just twists into place). Once I am done and happy with my final result I can post another thread on how I did it if people want (and if I find that it makes a considerable improvement, part of me thinks that the path of the air in the hvac box is sort of the low airflow culprit).
