Im getting the error that my windshield washer fluid is low; but when I try to put the fluid into the siphon, it doesnt go down the tube...anyone had a problem like this?

 

Maybe your sensor is malfunctioning and the washer fluid is already topped up. Cant think how a block would occur in this part of the car system.

 

Very possible that it is blocked, the filler tube to the neck gets kinked by the PCM harness.. but this doesn't "just" happen to be blocked, notice this usually after a PDI or if work was done in that area recently. If your filler neck is full and your getting the msg on the dash, you could always remove the RHF inner fender molding to see the washer fluid bottle..if the bottle is full or above the level sensor..your chances of a faulty level sensor is high..there not hard to replace and not to costly for the part

 

Mine drained slowly. dunno what the problem was, but I've only driven in the rain like 3 times, and neverrrr had to use the windsheild washer fluid, (apart from the drive home after I bought it).
