1993 Buick Skylark 3.3L V6 has no a/c working. After replacing all switches on dash, last one mode switch, a/c worked intermittently then went out completely. Replaced blower motor relay and resistor. Have power to relay. Pulled 25A fuse under dash and it's ok, but no power to it. Can you tell me where the power comes from to the 25A fuse; ie, ignition switch, ECM, a relay or elsewhere? I still need to drop fuse block to check wiring connection.

Power to that fuse comes from the ignition switch in the run position. Power windows work?
Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

The blower works hot wired, basically wanted to know where power comes from to fuse. Discretesignals says from ignition in run. That's what I was looking for. Now I'll drop fuse block to check connections from ignition switch. Thanks.

That feed also powers the power windows so if they work, the ignition switch is fine.

I don't have power windows, but the power locks work ok.

Door locks don't run off the key.
You are looking for an orange wire that feeds the fuse box from the ignition switch for that fuse.
