69 AC Blower keeps popping fuses
69 427 with factory AC.
The AC kicks on for a second and then pops the fuse.
I bought a NOS relay (not chinese crap) and I am going to install today. Thinking of going from a 25A fuse to a 30A. Any other suggestions? Worked fine a few months ago. I typically run the AC every few weeks to keep things fresh.

If a 25A fuse blows instantly you have a serious power to ground problem . DO NOT put a 30a fuse in .You can cause a bigger problem like wires melting . Go get yourself a shot finder. Its a circuit breaker that has 2 wire leads that gets hooked up in place of 25A fuse . With that in place you can trace out AC electrical system .
