Slow windows on Mk1 Eunos

[notax]

Really enjoying our Eunos but wondered what I can do to speed the windows up? They go up ok but take an age to go down. They also stutter a bit on the way down too. The car had very little use before we bought it. Any ideas?

[Disco You]

It's a common fault, a bit of searching will reveal what you need to do to solve it. I think it's to do with the wiring but I'm not sure.

Thanks - tried searching but the function has been out of order for ages... can anyone else help?

Elec. Windows - Electric windows get slow and stick over time, if they still go up and down fully the runners just need dousing in silicone spray grease from halfords

Mine are exactly the same. A squirt of WD40 in the runners helps for a short period. I just put up with them TBH and give them a helping hand on the way down!

WD40 will only be a (very) temporary fix as it dries out too quickly. You need a good silicone spray.

Yup, the halfrauds grease spray works a treat down the runners. Theres some spray to put down the rubber strip too for even better effect, cant remember what it is though, i'll have a look in my garage when i get home

If you really want to speed them up you need to re grease the runners that are in the doors ,its not that hard to do just a case of removing the door cards then wiping the old grease out of them and applying some new white grease in them.

I am sure there is a guide on how to do it somewhere

Firstly, buy an aerosol of white Lithium spray grease, and a can of silicone spray (not WD40).

Remove door card by removing handle and un-popping the card around it's perimeter.
Wind the window down if possible, and you'll see 2 channels that almost reach the door top. You need to re-grease these with the white silicone spray grease.
- I gave mine a shot of penetrating fluid before spraying ~ not essential, but I thought it might help!

Spray the grease into the channels as far as you can - operate the windows, and spray again - AFAIK you can't sensibly over-do this.
See if you can also get some on the top pulley & cable too (tricky, because it's shielded).

Spray the rubber vertical trim with the ordinary spray silicone - try to get some down into the part inside the door too.

Operate windows several times, and if they're better you've done it!

Spray the door card tops with the spray silicone (NOT the white stuff) where the glass runs up & down.

Re-fit door card (I sprayed a little silicone spray into door & lock mechanism, and a little on the "poppers" too).

Repeat for the other side.

Full benefit takes a couple of days, and you'll have windows like greased lightening!

[Don Phil]

^^^ Spot on.

I'll just add, i did find the grease makes its way out of the bottom of the door onto the paintwork outside for a while after doing this, make sure you keep wiping it off, dont want to mark the paintwork as its a sod to get off.

Thanks very much for all the advice Will get to work one evening!
