Has anyone experienced problem with the spray pressure of the front windshield wipers?

The pressure on my 2005 MCS seems reasonable when the car is stationary. But when I'm up to highway speeds, it struggles to get the spray more than a third of the way up the windshield. It is really challenging to clean the top portion of the windshield. All of this with a full tank.

I checked my lines tonight, and nothing looks kinked, or shows evidence of kinking after the bonnet is closed.

 

how do the nozzles look? When stationary, are you getting a nice fan pattern or more of a squirt? That might help, but if not, I tried
Or you can check the voltage to the squirter motor, to make sure corrosion on the terminals/wires hasn't caused a voltage drop, which can also give you the issue you are experiencing.

 

I have never seen a nice fan pattern to the spray.

Of course, I'm out of warranty, so would like to fix myself if possible.

 

To be honest it's not a fan pattern like the sprinklers in the vegetable section of the grocery store. However it should be hitting the windshield with at least two inches of width, over four nozzles. If the lines all look good, i'd check the voltage on the motor (if you have a multi meter or at least a simple volt meter, and could find the motor location, this should be easier to do than an oil change).

 

You just need to adjust the nozzles. Get a straight pin and move the nozzle up a bit. When traveling the wind is going to force the fluid down, so it won't be as high as when parked.

 

Just give it sone Viagra! That will fix the pressure thing!!!

 

I recently discovered a problem with a dislodged line in between the bonnet and the insulation. There were lots of squashed bugs on the freeway, but only the driver side nozzle was spraying and bone dry on the passenger side when I gave it a squirt . I tried again when the car was parked, then I noticed a stream of washer fluid leaking under the car on the passenger side. Not being a great fan of driving to the dealer, I decided to check out the fluid lines. Sure enough, I saw the passenger side line disconnected from the T-connector after pulling out the insulator.

I cannot believe such a hard-to-reach area, and MINI did not even use a zip tie to secure the connection. More to that, the big T-connector is not even secured by a clip of any sort. It was just held in place by 3 fluid hoses, flapping around under the hood the whole time. It will sure get idsconnected by itself again in time. Another quirky design by MINI.

Is mine broken or a clip is missing? Or is it the same for those who have seen it. I'm glad it works now after having fluid leaked all over under the bonnet.

 

The streams should hit pretty high up the windshield. When really hauling, they will hit lower. That's just the nature of the beast. That's also why a lot of fancier cars have the squirters on the windshield wiper arm.

BigShot has it right, just aim them a bit higher....

If, on the other hand, it's gotten lower over time, then I'd look for blockage. Junk can get into the tank, and it will plug the nozzles up. You can take them out, and force water or compressed air through them backwards to clean them out.

I have the opposite problem- too much pressure... and more 'squirt' then 'fan'. I end up with fluid all over my side windows by the time the wiper blades turn on.
Is there a way to adjust the volume of the spray, or adjust from 'squirt' to 'fan'?

 

no.

In your case, I would aim the jets lower. That way, the wipers will get to the fluid before it has a chance to run up and off the windshield at speed.
