Primitively bypassed?
What you did is a nice temporary work around.
Your circuit is elegant and simple.
The acid test is that it works.
I suggest going to your local parts-R-us for a 30 amp MAXI fuse and holder.
Please rewrite this and post it as a get your A/C working DIY.
There are many people who need your help.
Oh, oil the motor bearings on the blower, it will help some.
Have a great day.
