MX-5 Project log thread

Can a passing mod please change the title of this thread to "MX-5 work log and info thread" as I suppose it's not strictly an "ongoing project" as such! Ta :)
 
The plastic trim can be seen in the bottom right.

Fixing electric window mechanism

I may have mentioned that just before Christmas my driver's side electric window stopped working - didn't go up or down, and the glass would drop to about half way down. I pretty much knew straight away that it would be one or both of the two cables inside, part of the regulator, that have snapped.

So I bought two new cables (about £40) and they arrived just after Christmas.

It's now April and this morning I finally built up the required amount of "arsed" to fix it :D So I thought I'd shove it in this thread in case anyone cares, or needs to do the same job themselves!

First things first, the door must come apart

So speaker grille, door handle and door opener surround removed

step4.jpg



Door card removed
step3.jpg



Now you have to remove the dust/water guard plastic sheet, which is held on with nasty horrible black mastic that sticks to anything, and will come off nothing ;)
step5.jpg



With that lot removed, you have to remove the glass - no pictures of this step because I was too busy getting annoyed at the process, hehe, but you need to remove the trim on the top, outer part of the door, which is held on with some stubborn clips which must NOT be broken. Ask me if you want any more info on this

Nice dirty pane of glass
step18.jpg



Now the motor and regulator were removed, which was a case of marking up the position of a couple of nuts (their positions were adjustable) with Tippex, and undoing all of the nuts that hold these two items to the door. Out comes the mechanism, and...


Yep. There's your problem.

Cables had gotten all mangled up in the motor capstan
step6-1.jpg



And an overview of the mechanism when removed, showing the bit that snapped, causing the grief...
step7.jpg



...which is shown here - the tip of that wire should have a little stub which hooks in to a plastic holder on the window runner...

...which is circled here (you can see where/how the intact cable is held in, and the little broken tip is still stuck in on the other side):

It also caused the wire to jump off of one of the pulleys, further adding to the mess and tangle
step8.jpg



So with the old cables removed and discarded, I set about attaching the new ones, which is a bit fiddly..

You need to grease up the capstan, then wind the upper cable around the bottom hook in it (underside of it, not visible) approx. 2.5 turns, then wind the lower cable on to the top of it (visible below) approx 2.5 turns, grease up the cables thoroughly, then re-seat it on the motor's axle and make the sure the cables are sitting in the threaded runners on the capstan so as not to tangle it again
step10.jpg



Now you can thread the cable onto the greased-up pulleys and into the plastic lug on the runner that holds the cable - not as easy as it first looks, there's not enough slack at first without fully tightening the two plastic "seats" shown in the photo above and compressing the spring and white plastic lug, to reveal as much of the cable from the sleeve as possible

Once you've done this, it should wind round nicely. Now pop the metal cover back on to cover up the capstan, and this completes the re-assembly of the motor and regulator mechanism, which should now look like this:

step12.jpg


step11.jpg


step13.jpg



Now to get the bugger back into the door. Which wasn't too tricky tbh.


Shoving it all back in:
step14.jpg


step15.jpg



Regulator bolted up
step16.jpg



Motor bolted up
step17.jpg



And.. All done! Motor tightened up, regulator aligned and tightened up, window stoppers replaced, glass cleaned (Autoglym Intensive Tar Remover for the win) and replaced, and it goes up and down! wooo
step19.jpg


Door re-assembled
step20.jpg


step21.jpg


So there you have it. I was initially viewing this job with great trepidation, but after some initial snags, it wasn't too tricky! I feel I could re-do it in half the time. Which is handly, because my neighbour's MX-5 has got exactly the same problem, and guess who's going to be helping fix it!

I also decided that now was a good time to fit my new (to me) iPod capable head unit, thanks to a generous friend of mine. I wanted to be able to use my Ipod on longer journeys (to the rolling road in Gloucestershire, for example!) to alleviate some of the boredom of sitting on the motorway, and the radio is rubbish, so step up Alpine.


Old stereo, filthy interior
step1.jpg


Centre console removed to wire in ipod connection to armrest/cubbyhole
step2.JPG


iPod connection successfully wired in :)

Clean(ish) interior, new stereo. Works much better now!

Nice write up mate, I was tempted of converting my keep fit windows to electric, but with the MK1's knocking on a bit, most s/h windows are knackered.....I need the exercise anyway:p

Im fed up with my drab interior, so I painted the centre radio surround, but its a but too shiney so Im gonna go back to black, I quite fancy the Nakamae gear surround tho, and I want to flock the crash pads.



I'll stop trashing your thread now:p
 
Good stuff Howard, fixing the window looks pretty full on, I have encountered that black gunk stuff when replacing my locks, nasty stuff :o

I like the idea of the iPod stereo thing, but im pretty sure a fancy stereo like that would get nicked around here :(

Ive got my MX-5 running standalone on my megasquirt N/A at the moment, just started tuning it properly. Here is a picture of my MS1 V3.0:

Here is how the engine bay is currently looking:
