1988 Chevrolet G25 problems
The Chevrolet Van or Chevy Van (also known as the Chevrolet/GMC G-series vans and GMC Vandura) is a range of vans that was manufactured by General Motors from the 1964 to 1996 model years. Introduced as the successor for the rear-engine Corvair Corvan/Greenbrier, the model line also replaced the panel van configuration of the Chevrolet Suburban. The vehicle was sold both in passenger van and cargo van configurations as well as a cutaway van chassis that served as the basis for a variety of custom applications.
Produced across three generations (1964–66, 1967–70, and 1970–96), the model line was sold under a wide variety of model names under both the Chevrolet and GMC brands. The first two generations were forward control vehicles (with the engine placed between the seats); the third generation adopted a configuration placing the engine forward of the driver. The second and third generations shared powertrain commonality with the C/K pickup truck model line.
After the 1996 model year, GM retired the G-Series vans, replacing them with the GMT600-platform Chevrolet Express and GMC Savana.

Common 1988 Chevrolet G25 problems
The Chevrolet G25 1988 has been reported to have several common problems based on complaints from its owners. This article will discuss these problems in detail, focusing on the ECU and PROM, windshield wiper problems, odometer issues, and loose tilt steering column.
ECU and PROM
The Electronic Control Unit (ECU) and the Programmable Read-Only Memory (PROM) are crucial components of the Chevrolet G25 1988's electronic system. The ECU controls various engine functions, while the PROM stores the programming for the ECU. Over time, these components may fail due to various reasons, leading to issues with the vehicle's performance.
One common problem with the ECU and PROM is that they may become damaged or corroded, causing the vehicle to experience starting problems, stalling, or poor fuel efficiency. In some cases, the check engine light may also illuminate, indicating a problem with the electronic system.
To fix this issue, the ECU and PROM may need to be replaced. This is a relatively simple process that can be done at home with the right tools and knowledge. The ECU and PROM can be found behind the glovebox, and removing them requires no tools. Once removed, the wiring harness can be unplugged, and the new ECU and PROM can be installed. It is essential to ensure that the new ECU and PROM are compatible with the vehicle's engine and transmission before installing them.
Windshield Wiper Problems
The windshield wipers are an essential component of the Chevrolet G25 1988, providing clear visibility during adverse weather conditions. However, they can encounter issues over time, leading to poor performance or complete failure.
One common problem with the windshield wipers is a malfunctioning wiper motor. This can be caused by loose or damaged wires, blown fuses, or a faulty relay. To fix this issue, the wiring connections should be inspected for any damage, and a multimeter can be used to test the voltage at the motor. If there's no voltage, the fuse, relay, or wiper switch may need to be replaced.
Another common problem with the windshield wipers is misaligned wiper arms. This can be caused by loose or damaged wiper arm nuts, leading to poor contact with the windshield or erratic movement. To fix this issue, the wiper arms should be adjusted by loosening the nut at their base and repositioning them to sit correctly on the windshield. Once properly aligned, the nut should be tightened securely.
Odometer Issues
The odometer is a crucial component of the Chevrolet G25 1988, providing essential information about the vehicle's mileage. However, the odometer can encounter issues over time, leading to inaccurate or no readings.
One common problem with the odometer is a cracked or brittle gear. This can be caused by wear and tear or exposure to extreme temperatures. To fix this issue, the odometer gear can be replaced with a new one. This is a relatively simple process that can be done at home with the right tools and knowledge.
Loose Tilt Steering Column
The tilt steering column is an essential component of the Chevrolet G25 1988, providing adjustable steering for the driver. However, the tilt steering column can become loose over time, leading to a wobbly or unstable steering wheel.
To fix this issue, the steering wheel lock plate should be removed, and the steering wheel should be taken off. The steering wheel lock plate should then be tightened using a wrench, which will secure the steering column and prevent any wobbling or instability. It is essential to ensure that the bolts are tight and that the steering column is securely fastened to prevent any further issues.
In conclusion, the Chevrolet G25 1988 has several common problems that can affect its performance and reliability. By addressing these issues promptly, owners can ensure that their vehicles remain in good working order and provide safe and reliable transportation.
