XF headlight washers
Discussion
My passenger side front washer isn’t working, the nozzle comes out but no water, I have put a needle down the nozzles and also tried compressed air but no change, I understand that the nozzles come forward on the water pressure so it must be reaching the unit but can’t figure why I don’t even get a drip coming out, any thoughts, or how to access them, headlight removal maybe ?
Finally got around to trying to fix this, I have the headlight out and removed the washer unit, if I connect to an air gun on low pressure the arm extends and does nothing else, just as it does on the car, if I raise the air pressure a bit more I get air pulsing out of both nozzles evenly, raise pressure agsin and I get a normal air blast coming out, so it seems there is something in there that needs a bit more pressure to actually squirt, dilemma now is if this is faulty or old it be low pressure from the pump, any thoughts on how to determine which one ?
I replaced the pump last year after cleaning out everything I could and it worked, try again this year before the MOT test and both are not working, both push out but no spray, refit the original pump and I am back to where I was last year, drivers side now sprays but not passenger side, I removed the pump and put an air line on the hose and everything works but I need to apply more pressure before the passenger side sprays, so I either need more flow / pressure or to get the passenger side to work easier / earlier, has anyone else had this problem??
Hi, yes I did, first thing is to try with the engine running as the voltage to the pump will be higher so it pumps more water, a year ago this fixed my problem, this year I had no water from any headlight, with engine running I got the RH one working but not left, tried new pump, no change, eventually decided I had to change the LH nozzle arm, when removing you could see it had been leaking, this probably lost enough pressure so it wouldn’t come out the jet, it’s not as simple as a straight open nozzle otherwise the jet would operate before the arm is extended, anyway, after replacement the log one is very powerful, but the rh one is now weak, it seems they need to be reasonably balanced, so replace as a pair rather than individually
Good luck, you need to remove wheel arch liners, loosen bumper, remove headlight, then it’s easy, check out YouTube for headlight replacement
