    Sorry for more questions, I have a donor W124 with headlamp wipers, I fancy fitting them to my W124 that doesn't have them.

    Is this far more trouble than it's worth of is it a case of changing washer bottles headlamps and plugging bits in, I suspect it is as life is never that easy. Thanks a lot.

    More trouble than it is worth. I've switched from one with wipers to one without and no functional difference.

    This has been asked several times before. As Charles says retrofit is entirely possible but the system is unreliable with wiper motors seizing often. They do nothing for the lines either imho My previous suggestion would be to retrofit one of the later high pressure jet systems mounted on the bumper if you really need a headlamp washing system. :dk:

    I would think the wiring loom is the only difficult part. Fitting the actual motors, additional pump on the washer bottle and hose would be very easy.

    The wipers only work when the headlights are on and the windscreen wash wipe is used, and hence is connected to both. Maybe if you can examine the donor car you can check the wiring on that and make a decision.

    I think Billy124 may of added the headlamp wipers to his coupe? Do a search and you may find a thread on the same topic.

    Personally I think the w124 looks naked somehow without them, but they are also fairly pointless in terms of keeping the headlamps clean.

    If they are like the W201 then they have their own pump. You will need the trim strips for under but the motors just screw to the headlamp. I suspect the wiring loom is in place? I agree , though, that as a cleaning aid they are pretty useless. I find that it just costs me more in screenwash.

    Thanks all, I think a W124 looks more complete with the wipers. If anyone knows about the loom I'd be grateful, thanks

    I took mine off and put new (replacement) low brows in. Total pain. They got all floppy and the blades don't last long. You will probably need a new washer bottle or at least another pump for the existing bottle. Ill have a look on Monday at one Ian is breaking he might have the bits you need on that.

    Good Luck with your project.

    Hi John, no need to look, I've got an entire car with all the bits on there, it's just very difficult to see where one bit starts and the other ends, don't really want to embark on stripping either down until I know what is involved. Thanks,
    Steve

    Hi,
    I have retro fitted headlamp Wash/Wipe allbeit on a 202, but as it is an option the loom should be completly separate to the under bonnet loom and just cable tied too it. You should be able to remove quite easily, the only difficult issue I had was where the loom crossed the engine bay at the bulkhead at the back of the engine but you might not have this issue depending on where your washer bottle is.
    Mine had to cross from the fuse box on the drivers side under the bonnet to the passenger side where the washer bottle is, the loom then drops of a connection for the additional pump and then onto each of the wiper motors.

    I'll have a closer look when it's a bit warmer out, thanks

    (comparing my 2 W124's - one with wipers, one without) apart from the wiring loom, the existing washer bottle will have the space for the extra motor but with a gromet in the hole, you'll need to drill a hole in your lower headlamp metal trim for the wiper to sit, also require the motors themselves that screw to the bottom of the headlamp cluster. the wipers work every few presses of the washer sprays, only when the lights are on so i suspect the wiring loom is quite complex and maybe involves some sort of relay....

    Just reading silver saloons comment, regarding the relay, on the 202 I did have to fit a relay, the base of which formed part of the fusebox, all that was required was to put a relay in the base, plug the loom into a connector adjacent to the relay base, and fit the fuse. Washer bottle on the 202 was the same as silver saloon described the 124, just drain remove grommet fit the pump.
    To be honest it was one of the easier retro fits I have done, and as you have a donor car, should be quite easy to carry out.

    I decided against in the end, Its cetainly more effort then its worth as mentioned really. One bit of me still says i should have gone for it one bit of me says nah!?

    I also found out that one of the motors on the RHS was siezed up on my donor. Given the fact i had a mammoth task with the other bits i needed off it, I simply let go of doing this wiper conversion.

    Nothing will be difficult as i have grown to learn in the past few months. If you have a donor which you have then time, effort and patientce is all you will need :)

    take plenty of ref pics for yourself so when it comes time to fit you will know exactly where it goes for a professional retrofit.
