1997 Chevrolet Astro Problems
RepairPal has identified the most common problems with the 1997 Chevrolet Astro based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
The power door locks may stop working in one or more doors due to a failed actuator. Replacement of the failed actuator should correct this concern.
The outside door handles are prone to breaking—all doors are affected by this condition.
The headlight switch used on the Chevrolet Astro is known to fail through normal operation. Since the headlight switch is also integrated into the interior lights, a malfunctioning switch can cause issues with interior lights as well.
- Symptoms of a failed headlight switch include:
- Headlights and taillights failing to turn on or off
- Interior lights flicker, or fail to turn on or off
- Gauge cluster lighting off or flickering with headlights on
- Parking light malfunctions
This issue is well known with General Motors Trucks and SUVs, and is solved by testing and, if needed, replacing the headlight/dimmer switch. Bad grounding wires at the tail-lights, and dirty/corroded tow package wires can also lead to some of these issues.
Power brake systems using "hydro-boost" may leak power steering fluid from the hydro-boost unit located behind the brake master cylinder. Replacement of the hydro-boost unit is the common repair to correct this concern.
The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Our technicians tell us that operating the engine with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.
The idler arm, pitman arm, or center steering link may wear and cause excess play in the steering. If any of these components are replaced, the front end alignment should be checked.
Vehicles equipped whit a 4 speed automatic transmission may develop a harsh 1-2 shift and/or illumination of the Check Engine Light with code P1870 stored. This can be caused by wear of the bore for the TCC isolator and regulator valves in the valve body. This condition does not commonly occur until the transmission reaches normal operating temperature. If the valve body is worn, replacement will be necessary to correct this concern.
Illumination of the Check Engine Light may be the result of a loose or worn gas cap.
The spark plugs should be replaced every 100,000 miles. Our technicians recommend replacing the spark plug wires also at this time.
On vans with rear AC, the AC may stop blowing cold air due to a damaged AC line near the back of the engine. It is common for these lines to rub on the engine block, causing a hole in the line and a refrigerant leak.
