Electrical Issue: Help please

Hey Folks,
I've got a 2001 Freightliner Columbia.
The dash HVAC blower motor went out.
When it quit, the two radios; cb & music radio both quit, my HI beams quit working, and my ww wiper/washer quit.
EVERYTHING ELSE WORKS FINE; low beams, turn signals, flashers, marker lights (tractor AND trailer), jakes, radiator fan, dash guage lights, guages all work properly.

I replaced the blower first because the HI speed showed signs of the motor bearings going out. I checked all the breakers, relays, and fuses with my multi-tester, all good. Next, I did continuity tests on all my grounds and hots; replaced wire ends where I found corrosion, and soldered the ends to the wires. Did all my electrical maintenance as needed by a responsible operator.
Then:
I'm guilty of throwing some parts at the issue;
An ignition switch: $14.00 (legitimate guess ... lol), dimmer/flasher/turn signal module: $80.00 (ILLEGITIMATE GUESS), then I messed up and R&R'd the main fuse panel on the passenger side.
We won't talk about the price, but I know anyone with any knowledge at all knows what that price range is. My justification is that this truck has given me 18 years of relatively low operational costs, and the fuse panel showed signs of being corroded inside, so I don't feel bad ..........EXCEPT that I haven't yet fixed the problem.
Freight SUCKS right now.
I would MUCH RATHER use MY TIME to fix this rather than pay these shops these exorbitant labor fees to throw stuff at the wall like I have, and me still not have any more experience, knowledge, and wisdom after the fact. If freight was hot, then I would have put it in the shop, paid the bill, and been on down the street, hauling freight worth hauling.
I'm 60 years old, gonna be 41 next April, been truckin 40 plus years, but I'LL BE ###### if I'm gonna let this one kick my ###, so I'm asking for some help from like-minded operators who have a high level of give-a-#### like I do.
