If the window is skewing front to back or vice versa on the way up, the window is dragging on one of the guides - window is too tight or loose in the guides or a window channel in the door is not aligned properly. Resistance at both the front and back of the window in the channels as the window moves up has to be pretty much exactly the same.

Did you check out any u tube video's ? Corvette Blower Motor Module Diagnostics and Repair Ozzstar

Sounds like the Opti-Spark distributor on front of engine is defective that is the most common issue. Sold my Vette and have a spare new one for sale, want to buy it.

check intake manifold for leaks and also inspect all vacuum hoses also may be good idea to replace opti spark ignition module its located on the coil mounting bracket at front of right cylinder head if its been exposed to water , antifreeze, or moisture it can effect ur cars timing

I'm assuming that since you drove it home that the engine still cranks over and that it is not a battery issue like one of the other answers. If it does, but still doesn't start or tries but doesn't run smooth, that you may have gotten moisture under the distributor cap. That wouldn't show just by looking at the engine bay. You would have to look under the cap to be sure.

the distributor on the 93-96 lt-1 corvettes is located behind the waterpump, and harmonic balancer if you take the belt off you can undo three bolts on the balancer and it will separate

If you recently had a waterpump replaced or leaking, i would say its the opti spark distributor. Main problem with the LT1 engines the water leaks all over distributor that sits behind pump causing the start no start up. When ever you change the waterpump always include the opti spark and wired connector.

Does your cruise control not work also ? If not working, it will be the 3 way check valve located under the passenger side fuel rail cover, pull cover off you will see 3 air supply hoses connected to a check valve, they rot away and get holes in the plastic valve. replace with a new one from AutoZone $2.95 cheap

The hot / cold sliding lever is broken on unit. Common problem, the lever is plastic and breaks easily. If you take a flashlight and look inside the lever slot on the top right side you see a post it connects too. You could take a pick tool and move the post closer to you for heat or away for cold air.

DTC is Diagnostic Trouble Code

Was this problem there before you changed the fuel filter and cleaned the intake? If so, check your fuel pump.

Sounds like heater core is plugged. Are both hoses from heater core hot?

Your fuel pump or your catalytic is plugged. have it tested with a infrared gun it will tell you if the cat is bad and if it is replace it test the fuel pump for fuel rail pressure it should read 50 psi then hold to 20 psi for 1 minute.. Also check to see if the intake plate is dirty and if it is do a top engine clean, buy GM's top engine cleaner and run it threw the engine, if you have carbon buildup the compression and cause the car to run bad and the knock sensor will not be able to adjust time. I know this sounds silly but these three things will cause your problem and so will a bad fuel filter.
