Sounds like a slick or worn serpentine belt or low level in the power steering pump. A bad belt will grab just enough at higher speeds not to impact the power steering or other accessories but not at lower speeds.

You have what they call a hydro boost system, the power steering pump give power steering assist, and give power brakes, so if your power steering hose looses fluid you get not power steering and no power brakes, So check the power steering hose for leaks if there is no leaks replace the powersteering pump

My 1996 GMC Suburban has 170600 miles on it. In the last week, it drives fine until you travel about 1/4 mile & reach 30 mph. Then, you loose acceleration. When you push the gas, the engine just revs....


Try dropping the tranny fluid and changing the tranny filter and filling with fresh fluid. Sounds like the tranny is sleeping between shifts.

1995 gmc serria will not start no click from starter, manual trans


replace the starter. Being a manual transmission you should be able to pop the clutch to get it going till you replace the starter. If you don't know how to pop the clutch follow these steps. That way you can still drive the car. When need to.
  1. Get inside the vehicle and depress the clutch to shift the car into "Neutral." Insert the key into the ignition and turn it to the "On" position. This is the place the key would be after a normal turn of the ignition switch for starting. Instead, with a clutch pop, the ignition will already need to be on so that when the engine is turned over, the key is in the On position.

  2. Move the car in position to be pushed from behind or sent down a slope for the starting procedure. Check to see that the brakes will work when pressed and how hard the steering wheel will need to be turned before the vehicle is started. Power steering and brakes will make both systems work poorly until the vehicle is started.
  3. 3 Sitting inside the driver's seat with the clutch depressed, put the shifter into first gear. Keep your foot depressed onto the clutch and the brake pedal without depressing the brake pedal. Roll down the window and signal to your helper to push. As the car rolls, you will steer toward any slope that will assist the helper in getting the car down the street. Allow the momentum of the vehicle to increase to constant motion.
  4. 4 Release the clutch quickly and be prepared to throttle the gas pedal as the engine is turned over by the motion of the vehicle. When in gear, the engine will be forced to crank and the ignition will send a spark for a start. The quicker the vehicle is going before the clutch is released will determine how many times the engine will turn over. More cranks equal more opportunities to ignite the gas and air for combustion and the engine to start without a battery or starter

Power steering and brakes dont work are they connected somehow and how would i fix this problem


Hello cindygariepy: My name is Roger and I will help you. Yes they are connected. The truck uses a brake system called Hydra-Boost. There is no vacuum booster like the cars use. Hydro-boost brakes use the power steering system as a source of power assist for the brakes. You need to check to make sure the fan belt is still on the engine. Should the belt brake you will loose power steering and brakes. Next check to make sure the power steering has fluid. If you have a leak in the power steering system and the system is extremely low you will loose steering and brakes. Generally when the system is low you hear a noisy growl when turning the steering wheel. These are the usual problems that occur when you loose both the power steering and brakes at the same time. There is one other part that could cause the condition . That would be a hydro-boost failure. If it fails there would be a lot of fluid leaking at the driver side of the vehicle in front of the driver seat outside on the ground. Power steering fluid is a clear oil. Should you need further help please just ask. Thank You for using Fix Ya. Roger

POWER STEERING PROBLEM


You either crushed a line or a cooler for the power steering. The brakes are hydro boost so the braking power comes from the ps pump.
