Common 1999 Chevrolet Gmt 400 problems

The Chevrolet GMT 400 1999, also known as the Chevy Silverado, is a reliable vehicle, but like any other car, it has its share of common problems. Here are some of the issues reported by owners of this car, based on search results:

1. Windshield Wiper Motor Component Failure: The windshield wipers on models made between 1990 and 1999 may stop working intermittently due to a defective wiper motor control board. This problem is common in 1988-1998 GM pickup trucks, and auto manufacturers issued recalls for this problem on some models. If you experience trouble with your windshield wipers, check with a dealer to see if there is a recall on your vehicle. If you have a faulty wiper motor control board, your wipers may at times stop working, fail to turn on or keep running after you turn them off. You might also find your wipers only work on one speed setting. When the wipers are not working, you should hear the motor control box buzzing. As a temporary fix to the problem, lightly tap on the control box, and the blades should start working again. For a more permanent fix, replace the wiper motor control board.
2. Coolant Leaks or Oil Leaks from Intake Manifold Gaskets: The intake manifold gaskets in 1988 and 1998 GM pickup trucks often develop external engine oil or coolant leaks. These vehicles may also develop internal coolant leaks that cause coolant to mix with the engine oil, which can damage the engine. This problem most often occurs at around 175,000 miles. Fix this problem by replacing the intake manifold gasket, which will most likely cost somewhere between $300 and $450.
3. Front Wheel Speed Sensor Failure: The front wheel speed sensors or anti-lock brake system (ABS) sensors may fail in 1988-1998 GM pickup trucks. This issue may cause the ABS warning light to turn on or the ABS to activate erratically. Many users report the ABS activates on dry roads at slow speeds. Replace the faulty sensor to fix this problem.
4. Parking Brake Failures: In 2005, GM issued a recall for parking brake failures in 1999-2002 Chevy Silverado and GMC Sierra trucks. The parking brake cable may not engage the parking brake shoes properly, causing the vehicle to move when parked on a slope. This problem can lead to accidents and injuries, so it is essential to get it fixed as soon as possible.
5. Distributor Problems: The distributor is a critical component of the ignition system in the Chevrolet GMT 400 1999. It is located right here, and this is how the spark plugs get their spark. If you have a V6, it's gonna be a little bit different. And if you have a diesel, you're not even gonna have this. So let's talk about how this gets the spark to the plug. Under here, there's this little wheel, and that's gonna send a signal to the module. There's a module back here. And that module is going to send the signal to the coil. Now, there's only a single coil on this vehicle. It's not a coil over plug. So, it only has one, doesn't have eight, and then coil is gonna send the spark to the top of the distributor cap. And then it'll go through the rotor, the rotor is gonna spin and then send out the spark to each individual wire which goes to the spark plug. It's always a good idea to keep up on your maintenance with the cap and rotor replacement or plugs and wires. And then also, what happens on this sometimes you'll get a crack in this wheel right here and also the ignition module right there. Sometimes those go bad, and that's gonna give you no spark or intermittent park, which isn't good.

These are some of the common problems reported by owners of the Chevrolet GMT 400 1999. It is essential to keep up with the maintenance of the vehicle and address any issues promptly to ensure the safety and reliability of the car.
