Couple of things, one mechanical, one electrical.
 

My V40 comes up for MOT in a month and I think the off side handbrake cable is seized, is it a major job to fix/replace it?
Second fault just presented itself, hazards have always worked ok but my pre mot test I couldn't shut the little devil off, eventually got it off but is it possible to service it? Or must I buy one as it seems that the part is discontinued and only used ones available.

Seen a guide on the hazard switch somewhere on here before, mine recently refused to turn off until a few attempts but it hasn't done it since

The hazard switch is definitely something that needs a gentle touch - mine jammed once but if you take it out you can reset it so it works again (assuming you've not bust it!).

I don't think it's the internal wiring that plays up, just the quality of the fittings, so if you can get a second-hand from somewhere I'm sure that'd be ok (but try releasing yours if it's jammed first)

Thanks, I've bought a used spare to put in shortly.

Booked the car in for MOT today at 15.00 hrs, as is my wont I took it up the motorway to get the cat hot and as I was returning a large rock was thrown up by the lorry in the nearside lane, hit the wiper drive just in front of me then the screen.
Wiper immediately goes into megasqueak mode and there's a 6" crack from the corner of the screen.
Stopped the car and pulled the wiper out a bit and the squeaking has gone.
Thought I've nothing to lose so took it in for the test, here's a cut and paste of the cert. Not a mention of the screen.

BTW it's a 2002 1.8 GDI that my son gave me last year.
Just booked in with GA, £75 for a new screen fitted.

Forgot to mention, handbrake cable wasn't seized, 1/2 a turn on the adjuster nut and she was a good un. Very relieved it went through without major expenditure.

The right hand cable (and probably the left) is a pig to replace on the ground. It's getting it though the double skinned section of the floor then feeding it around the fuel tank, the hundreds of supporting clips that don't go back on in place.....but it will work once you get it onto the caliper lever!

Thanks for the replies, I sold it yesterday. Couldn't be bothered with fixing it.
