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.

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.

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.

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.

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

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?

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.

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 brake servo needs refitting and ensuring correct torque

Diagnosed it for him as the lock cylinder not being straight.With keyless entry and alarm systems, the key locks (and the transmitters) use ground triggers for a couple of things.First of all, a ground trigger is used to disarm the VATS. I think most of us know that.Second of all, a ground trigger is used to wake-up the light-timer board. When you open a door, the door jam swithes provide that same trigger. And, as long as the ground stays active/connected, the lights will stay on. Only AFTER the ground drops will the timer cause the lights to turn-off after 30 seconds.I have to say it would be tough to catch/diagnose the door lock causing the issue by being skewed, but I can see it happening.

Sounds like you might have a headlight relay stuck on or a bad switch.

Not sure I follow your question, but an open fuse is the same thing as a blown fuse. The connection is open.

Are all the vents working? Does your Cruise Control work (properly) it may work and shut off. If your vents are working is only hot air or cold air coming thru, or just your defroster vent?You have a 3 way check valve under fuel rail guard on passengers side, its a pastic barrel shape thing it rots and creates holes in it causing your ac vents and cruise control to malfunction.next your heater control unit if you have the one with a slider to regulate the hot or cold temperature breaks easily inside unit, its only plastic. Its an arm inside unit to control the temp in car it slides a door open or closed for heat. If you look where he slider enters thru that hole space you will see a post it sits on to open and close .

More information will help you get more responses.

Thats odd.Are you getting power to the switch ?

Sounds like the thermostat is sticking, or you have air in the cooling system. Depending on how the overflow tank is used, you may have to run the engine with the radiator cap off to burp the system and finish filling it.
