'91 Blazer Silverado, advice for buyer?

Hey gang,     I'm looking to buy a certain '91 full-sized Blazer; I'd appreciate hearing about any trouble-spots that I'd want to check out, and maybe some fix-it
The Good:     Silverado, 350 fuel injected, not a diesel, manual locking hubs, ABS, PW, PL, A/C, cruise, electric mirrors, new 350 automatic trans, new brakes/rotors, new oversized exhaust system, trailer hitch, 11.50 Goodrich TrailGrabbers on aluminum wheels, black truck, black top, no dents, no body rust, no oil smoke.
The Bad:     Power door locks not working (not even a click), no instrument lights, rear window keyswitch bad (rear window works with the dash switch okay, though), passenger's window sticks a bit, and the locking knob/rod is gone on that side.
The Ugly:     Clearcoat is crumbling to dust in several areas; paint is okay.
Is there any halfway decent fix for old clearcoat, short of a new paint job? How can I tell if the power locks are good or bad? Anybody know how to dis-assemble the doors? Are power door locks on a separate fuse (or what else shares that same fuse)? Any information sources better or cheaper than CarFax? What did I miss? :-)     Thanks in advance for any help. Cheers, Red -- ************************* Replies will bounce, unless you remove the letter A from my email address.
