The engine and the automatic transmission in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exception to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems.

On a vehicle this age, it is likely that the fans themselves have worn out. Test the fans by running battery power directly to the positive contact. If they start, they are OK. On 4.3 motors, there is also a seperate temp sensor to signal the fans, usually called a fan switch. I believe it operates independent of the ECM. Another possible culprit is a bad ground at the fans or even a loose or corroded negative battery cable.

I dont know which model you have. My sons 94 caprice classic fully loaded he got used at an auction. Didnt know it at the time but it was one a cop car. Look on the front of engine under the crank case there should be something called an optispark on it. It has four wires coming out of either side and they run back to your plugs. Thats what was happening to my sons

The car needs to be scanned. It is free at Autozone, Oreilys, and Advance autoparts. Get the Code number for the bad part. The clerks can tell you what is wrong.

I am assuming you are talking about the washer fluid.
If the tank is full and the light is on the sending unit has failed.
Same thing would be true for the coolant if it has a low coolant light and the radiator is full.

It is normal for the engine to run hotter when using AC, if it is overheating you may have a slipping belt.

V6 or V8 ? Both engines use a flat cap and standard rotor.
The coil is triggered by two modules, one inside the bottom of the dist and the other mounted on or near the coil. Any of these parts could fail.
You would check to see if all of the plug wires are dead, and if the coil and module has batt voltage with the key on. Also check to see if the coil will fire if not connected to the dist cap.

The ignition key switch sends power thru the neutral safety switch to the starter motor solenoid mounted on the starter motor.
If the car has an anti-theft system the key has a micro chip that signals the system to function.

You 1st need to check for power @ your starter motor. The big wire is constant power. The little wire will only receive power when the key is in the start position.
