RepairPal has identified the most common problems for 19 Pontiac models based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
The 30amp high speed cooling fan fuse may blow due to high start up loads associated with the high speed cooling fan motor. Our technicians tell us the high speed cooling fan wiring and fuse should be upgraded to a 40amp circuit to correct this concern. The fan wiring MUST be upgraded along with the fuse to handle the increased current flow.
The engine vacuum hose to the MAP sensor may crack resulting in a vacuum leak causing the engine to run rough and/or stall.
One or more of the power windows may stop working due to a failed window switch. Failed switches will require replacement.
The anti-lock brake (ABS) accumulator may fail causing loss of power brake assist. (The brake pedal will become very hard.)
The rear light socket plate may fail causing a brake light or other rear light to stop working.
The high pressure power steering hose will commonly leak fluid and should be replaced if this is the case.
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.
Various electrical issues may be caused by poor terminal contact at the body control module (BCM) electrical connectors. Proper diagnoses will be required to confirm faults are related to poor BCM connections.
The turn signal switch in the steering column may fail causing the turn signals not to work on one or both sides.
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.
