1999 Pontiac Firebird Problems
Rear Transmission Mounts Commonly Fail
Failure of the rear transmission mounts is common.
Head light door actuators may fai
The head light door actuators may fail causing the head lights to become stuck in the raised or lowered position.
Dim Tail or Brake Lights Due to Faulty Light Sockets
The tail or brake lights may be dim due to a poor ground connection inside the light socket. Failed light sockets will require replacement.
Check Engine Light With Code P1870
The 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.
Check Engine Light Due to Restricted Secondary Air Injection Check Valve
One or both secondary air injection check valves may become restricted causing poor air flow resulting in illumination of the Check Engine Light. It is often recommend to replace both check valves even if a fault code is set for only one bank of cylinders. Replacing only one valve may result in a return trip to the repair shop.
Hood and Rear Hatch Supports May Fail
The hood and rear hatch supports may fail causing the hood or hatch fall back down after being raised to the open position. Replacement of failed supports is recommended.
T-Top Models Are Prone to Water Leaks
The t-top models are prone to water leaks from the t-tops weather strip seals. Our technicians tell us that replacing the all of the t-top related weather strips will commonly correct most leaks. Care should be taken when removing and installing the t-tops in order to avoid damage to the weather strips.
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.
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.
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.
Rear hatch won't close due to trunk pull down switch failure
Roller on window guide may break
The roller on the window guide attached to the bottom of the window glass may break off and cause the window to come off track.
