Hello

I am have the same issue as you.

My blower stopped working for 10 seconds 2 days ago but came back... but yesterday it just plain stopped working. A/C button does nothing, Fan switch doesn't respond.

Can you please confirm that the unloader relay was in the Fuse box or at another location?

Thank you

Also known as a relief relay. Standard square relay regardless of how it's shown on the diagram.

Thank you Mike.W

My issue turned out to be a slightly lose A/C-Blower fuse.

I had checked it twice, and although it looked snug, the contact wasn't stable.

All is well...
