Don't get louder, improve your argument.
I'm in the process of getting a 2000 Ranger 2.5 back on the road and in some of the tests with engine running, the air conditioning and fan speed (both together and with AC off) bog the engine down. The faster the fan speed, the more it bogs down.

I'm replacing coil packs today, but I don't think that'll do anything for the AC. Any suggestions on where I should start looking for this gremlin?

Might check the blower motor and/or the resister/module that controls its speed.

As long as you are not on defrost when are considering the A/C off it doesn't sound like it has much to do with the A/C

Good call on the module. I replaced it and it works great!
