Why do my cooling fans not work sometimes?

2003 Ford Focus. The cooling fans usually work when they need to, but sometimes they don't which causes the car overheats. I've replaced the entire cooling fan assembly including the resister and a resister connected that was burned up. I'm still having the same issue. It happens when I drive around in the heat for a while. I've also replaces the thermostat and the temperature gauge with no luck.

Ford Focus ST Hatchback seats?

I've been looking into the used market for the Focus ST (2013-2014) and from what I can tell most of them have the Recaro front seats which are notorious for not being friendly to taller and bigger guys. A two categories I fit into. I was wondering what were my options for replacing them just in case I can't find a used model with out the Recaro's in them. Could I take it to a Ford dealership and trade the seats in for the standard one? Or just pay for he standard ones and have either a dealership or autoshop install them for me? Or are there other options I'm not thinking of?

Car Alarm goes of repeated throughout day?

My ford Focus Zetec 2007, Alarm has been going off every couple of days, a few times in a row. It had indicated that the bonnet was open when it wasn't, we eventually realised there was a loose wire which has now been fixed, this was about a week ago, it had gone of once or twice since, no bother.

until in the last 24 hours I would say it has gone of around 10-13 times, maybe more as I had to go shopping and left it for a while, I and others have checked the doors, windows, lights and the bonnet again, both before it was locked and after, but can't seem to find a problem.

I had been using the normal key a around 6 months, (this isn't the problem) as my FOB key is broke, and I haven't actually been able to find a new casing for the this particular key.

Would anyone have a solution to this, bloody alarm,
any help would be appreciated, I don't want to have to get up 6 times a night to shut the bloody thing off, and I really don't want to have to leave it unlocked.
