Mk1 Mondeo, o/s/f window goes down but not back up...
Is this likely to be a faulty "one touch down" relay? (it clicks when 
"up" is pressed on the switch)
Just a little confused because it's only a four pin relay, and they 
aren't usually changeover types.

Had a nightmare trying to work out the wiring becuase the diagram in the 
Book of Lies is wrong - but just close enough to look right...
Anyway it's not the motor or mechanism, fortunately, because it happily 
goes up and down if power is applied direct to the motor and the switch 
is ok too.

I believe it should work ok without the one touch relay plugged in, so your 
likely culprit is the switch.

Are you sure its not the switch? These do play up. Although they are not 
designed to be dismantled, you can take them to bits without too much 
trouble and clean the contacts. This will fix the problem about 70% of 
the time.

I did dismantle the switch and checked it out with a meter too - it 
seems to do what it's meant to, but the 12v feed for the "up" position 
seems to be routed through the relay.
Which is the part I couldn't follow, what with it being about 10pm last 
night and about to rain...

Think I'll just buy a switch and a relay and be done with it ;)

LOL! Last time I attempted that, admittedly with an all singing all dancing,
one shot up, one shot down etc etc switch, upon releasing the actual rocker
part oh-so-carefully I was showered in springs, contacts, ball bearings and
god knows what else!

There wasnt a cat in hells chance of re-assembling the bugger without
several bits left over!!

Tim..

It was the relay in the end - reckon the heat must have cooked it ;)
