I am out today for an errand and decide to get gassed up. But after topping off the fuel tank my Chevrolet G30 would not start. I turn the key but it would not click. The radio would not even come on. I check on the headlights, the dome light, and the horn and they work fine. What must be wrong with my van?
This must be an ignition switch problem. The ignition switch is the one that is responsible for delivering power to your van's electrical accessories, fuel, computer, and ignition systems. It is the route where current from the battery is delivered to the starter in order to start up the engine. But if the switch itself becomes defective, then chances are the van would not crank at all. So, it is either some of the electrical parts of the ignition switch are loose or the pins inside the cylinder might have been worn out. It is best to have a professional look inside the mechanism so you would know if you need to shell out cash for replacement or just for repair.
My 1991 Chevrolet G30's fan only blows air through the defroster. What must be causing this, and how do I address the problem?
First, you need to check how many blower motors you have under your dashboard. This circumstance happens if you only have a single blower motor that takes charge of your vehicle's ventilation requirement. The case of air getting redirected from the defrost to the vents then to the floor indicates the control is either through a mechanical or electrical system. Wirings on the levers and arms could be misaligned, loose, or broken. It could also be that the fuse is blown, or the relay or valve is blocked. This is the perfect time to hire an experienced mechanic to look into the problem and get immediate solution.
My G30's horn sounds weird. It has turned into an annoying honking sound like that of a hungry cow. Could it be some wiring problem?
Most cars are equipped with two horns—the high tone horn and the low tone horn. You get a normal sounding horn when both of these function well. As with your case, either of these two horns could be bad. To test it, you need to look under the hood and locate both horns. Have somebody honk the horn while you use your hands to feel each horn. Take note that a non-vibrating horn is the one that is defective. If you know anything about how the wirings are supposed to be aligned, then you could replace the part by yourself. However, you can always seek professional help to ensure it is done accordingly.
Why does my van shake and vibrate when I step on the accelerator and rev between 30 to 35 mph?
There could be a variety of reasons your van shakes and vibrates when you tend to accelerate. It could be about tire rotation or wheel balance. However, it could denote a more serious problem, which involves steering or suspension problems. Do not ignore this issue and address it as early as now to avoid both a more costly replacement and road mishaps from occurring.
