I filled the windshield washer fluid and it will not spray out.

Mercedes-Benz S350 Problems

Brakes
  • Due to the size and materials of the brakes on these vehicles, the brakes start to squeak around the 50 percent wear point. The brake rotor surfaces become uneven, causing a lip to form at the outer edge of the rotor. Because of this, the rotors are usually replaced when the pads are worn (pad life varies depending on driving style and terrain).
  • Brake fluid should be flushed every two years to prevent premature anti-lock brake system (ABS) failure.
Engine
  • Oil leaks can develop around the oil filter housing.
  • Fuel leaks can develop around the high pressure fuel injection pump.
Suspension & Steering
  • Irregular and premature tire wear can be caused by the lower control arm bushings cracking and causing excessive movement at the control arm pivot point. Ball joints can also wear out prematurely, causing similar tire wear symptoms.
  • The tie rod ends, drag link, and idler arm in the linkage of the steering system can wear out.
  • There is a steering dampening shock that will leak fluid when it goes bad.
  • Vehicles with level control that ride harshly in the rear (no give in the suspension, like you are riding on a brick) may have bad dampening actuators. The actuators should be replaced in pairs.
  • Some models have tandem hydraulic pumps—one section for power steering and the other for suspension adjustment. These pumps are prone to leakage from either section.
Drive Train
  • A vibration felt through the center floor of the vehicle can be caused by driveshaft flex discs, which crack and shred, causing excessive driveshaft movement. Not repairing these can cause damage to the driveshaft center support bearing, or, in the worst case scenario, damage to the transmission or differential.
  • High mileage vehicles can leak from the transmission oil seals.
  • High mileage or older vehicles develop leaks at the differential seals and cover; the whole unit needs to be resealed to repair the leaks.
  • The bushings for the shifter lever wear out to the point where they break and fall out. This causes excessive movement (loose feel) in the shifter lever and a clanging-type noise when changing gears.
Electrical & Lights
  • The insulation degrades on the engine wiring harnesses because the insulating material falls off of the wires and leaves the conductors exposed. This can cause many problems depending on which wires are exposed and what they touch.
  • Throttle valves can suffer electrical failure.
Heating & Air Conditioning
  • Other than a defective motor, a bad switch or blower motor resistor assembly can cause inoperative heater blower motors.
  • Leaks at the AC compressor, hose manifold for the compressor, or the evaporator core can cause poor AC performance.
  • The climate control system can fail or perform erratically due to internal wear in the climate control unit buttons.
  • A cracked or broken heater core outlet housing can cause a coolant leak near the bulkhead (firewall).
