Regardless, my vehicle is a 2014 SL400 and it is great. However, in the last week or so, the windscreen wiper fluid has been unable to dispense onto the screen.
The wiper blades are equipped with small apertures that spray the fluid directly onto the windscreen, as opposed to ejecting it from the top of the bonnet.
Upon pressing the squirt button, a little quantity of fluid is emitted from both blades, but, it is insufficient to adequately cleanse the screen.
The wiper blades were changed around 3,000 miles ago and functioned well until lately.
Does anybody possess any notions on the potential cause of the problem?
From my perspective, it seems unlikely that the pump has entirely failed because there is still some fluid being discharged. However, it is possible that the pump is deteriorating and nearing the end of its functionality. The wiper blades cannot be the cause since they are almost brand new. It is not possible for the pipes to extend from the point of division to each individual blade, assuming that is the configuration.
Do you have any insights or advice to assist with the diagnosis?
Furthermore, I would want to address another separate matter.I am experiencing a bothersome buzzing sound originating from the driver's door, which I am unable to pinpoint. I have applied lubrication to the door seals and inspected the door pocket for any loose objects, but unfortunately, the issue persists.
