97 2.3ltr blower questions

Okay I bough this used over 7 years ago and the a/c has never worked and the blower only worked on highest setting.

Recently there have been some problems with the pulley system that also seemed to effect the blower fan too because it no longer would work at any setting. The idler pulley, power steering pump and belt were replaced and briefly the blower worked again. Then the a/c compressor went on the fritz and no more blower. I just put on a new belt to bypass the a/c compressor and still no blower. I found a blown fuse and replaced that but still nothing.

I already know that the resistor pack is bad because the settings never have worked properly, but could that be the only thing? The question is should the highest setting still be working even if the resistor was bad?

Would problems with the belt tensioner have any effect here even though the AC compressor has been completely bypassed? Or was the timing of the pulley problems just a coincidence?

The obvious next pieces to look at would be connectors and motor. But at this point I'm thinking it might be cheaper and easier to just buy a plug in heater than to replace connector, resistor, and motor. Any thoughts?

Change the resistor pack. The fan still worked on high because every speed below high runs through the resistor pack full blast gets straight batt voltage bypassing the resistor pack. And yes the pullys were just a coincidence.

Yes, but the blower no longer works on high speed. So since it's doesn't work when bypassing the resitor pack then that means there must be another problem too.

Can I get the blower out from under the hood or do I need to take the dash apart?

Blower motor works when battery is directly connected. I replaced the relay and resistor pack and checked all the fuses but it still doesn't work. Control Switch appears to work because I can hear it making noises as I click through the settings. What's next?
