1993 Pontiac Grand Am
Coolant Leak From Heater Core
The heater core under the right side of the dashboard may leak engine coolant which can puddle on the passenger front floor. The loss of coolant may cause an engine overheating condition. Our technicians tell us that removal of the dash board is necessary to replace the heater on these vehicles.
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.
Power Window Not Working Due to Window Motor
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.
Engine misfire due to ignition coil housing failure
Key Stuck in Ignition Lock Cylinder
The automatic transmission shifter may fail causing the ignition key to become stuck in the ignition lock cylinder.
ABS light due to weak battery or burned out bulb
A weak battery or a burned out brake light bulb may cause the ABS light to illuminate.
Transmission Fluid Leak From Cooler Line
The rubber section of an automatic transmission cooler line may develop a fluid leak . In some cases the leaking section of hose can be replaced. In others, the complete cooler line must be replaced to correct this concern.
Failure of Instrument Panel Lighting Due to Faulty Panel Dimmer Module
The instrument panel and switch backlighting may fail due to a faulty dimmer control module. A failed module will require replacement.
Rough Running Engine Due to Vacuum Leak
The engine vacuum hose to the MAP sensor may crack resulting in a vacuum leak causing the engine to run rough and/or stall.
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.
Timing Chain Tensioner/Guides May Wear and Cause Noise
The timing chain tensioner and guides are prone to wear and may develop an abnormal noise, requiring replacement.
High Pressure Power Steering Hose Can Leak Fluid
The high pressure power steering hose will commonly leak fluid; it should be replaced.
The Engine May Stall After Extended Freeway Driving
The torque converter clutch can stick "on" after extended freeway driving causing the engine to stall when coming to a stop. Our technicians tell us when this occurs, the engine usually will restart and stall when put into gear. After allowing about twenty minutes for the engine and transmission to cool down, the engine will start and the transmission will operate normally. Replacing the torque converter clutch solenoid, transmission filter, and fluid will generally correct this issue.
Engine Overheating Due to Head Gasket Failure
The 2.3L 4 cylinder engine can be prone to head gasket failure. This can result in coolant loss and engine overheating.
Engine Control Module (ECM) can fail
The Engine Control Module (ECM) can fail causing stalling, and engine and transmission drivability concerns.
Fuel injectors can short-circuit
Fuel injectors can short-circuit electrically causing a rougher than normal idle and reduced performance.
Poor Ride/Handling Due to Worn Suspension Struts
The front struts may show signs of wear, or be excessively bouncy ride at freeway speeds. This may begin to occur at around 75,000 miles.
Front or rear exhaust manifold may crack
The front or rear exhaust manifold may crack causing an exhaust leak. Our technicians tell us the manifold should be replaced to correct this condition.
O2 sensor may fail causing the engine to run rich
The oxygen (O2) sensor may fail causing the engine to burn to much fuel and may cause the check engine (SES) light to illuminate.
Engine Oil Leak From Intake Manifold Gasket
The intake manifold gasket can develop external engine oil leaks. The intake manifold will need to be removed and the gaskets replaced to correct this issue.
