1991 Chevrolet Astro Problems
Power Door Locks Stop Working
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.
Outside Door Handles May Break
The outside door handles are prone to breaking—all doors are affected by this condition.
Power Window Motor May Fail
A door window may move slowly or stop in mid travel due to a failing power window motor. The affected window may start working again after the motor cools off. Replacing the faulty window motor will commonly correct this concern.
AC Not Cold Due to Refrigerant Leak
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.
Power Brake Units May Leak Fluid From Hydro-Boost Unit
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.
Idler/pitman arm or center steering link may wear
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.
The Fuel Pump May Fail Causing the Engine to Stall or Crank Over But Not Start
The fuel pump may fail causing the engine to stall and not restart. Our technicians recommend replacing the fuel filter every 30,000 miles to help prevent undue strain on the fuel pump.
Transmission Leak From Output Shaft Seal
A fluid leak may develop from the transmission output shaft seal. This leak may cause the transmission mount to become oil soaked and require replacement of the mount along with the leak repair.
ABS Light Due to Brake System Control Unit Failure
The Anti-lock brake system (ABS) control unit may fail internally causing the ABS warning light to illuminate.
Coolant Leak & Engine Overheating
A coolant leak may develop from the water pump. The engine may overheat as a result of the coolant loss. A leaking water pump should be replaced.
Intake Manifold Gasket May Leak Coolant or Engine Oil
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.
Oil Leak From Distributor Shaft Seal
Failed alternator can cause "no charge" condition
The alternator may fail, causing a "no charge" condition. An internal bearing may also fail and cause an abnormal noise. If the vehicle is driven too long with a failed bearing, the alternator may stop turning, which can cause the serpentine belt to break or the engine to stall and not turn over.
Driveability Problems Due to Internal Distributor Fault
The distributor may develop internal faults. This can cause a rough running engine or stalling condition, the Check Engine Light may or may not illuminate. Our technicians tell us that the distributor should be overhauled or replaced to correct this concern.
