intermitent

hello the past couple of days i have had the brake pad warning indicator come on. not everytime i get in the but sometimes it does and soemtimes it does not? firstly... my brand new Disks and pads ahev one been on for about 500ish miles and secondly, i have the DS2500's on and they were...

My intermitent wiper is well......intermitent :D some times it works and others it doesnt. Likely problems are probabily the switch (stalk) or the relay correct? Any one know which is more likely? or how i can figure which one it is?
