Hi folks. I have a recently bought Bravo 1.6 HLX which since purchase has caused me no end of problems. About 4 days ago the wipers developed a fault - the flick wipe stops as soon as you release it (ie in the middle of the windscreen) and the other settings all work at the same speed - it's either on (fast) or off.

I've been told that the problem is most likely the relay in the wiper motor, does this sound likely?

This morning the engine management warning light also came on. Is it possible that this is related to the wiper problem? I really hope it is because otherwise I have to go and pick a fight with the garage I bought it from... I've only had it 3 weeks and it's needed new pads, discs, bonnet release catch and a headlamp bulb and now this lot. I was told by a friend after buying the car that Fiat stood for Fix It Again Tomorrow but I thought that was a joke :/
 
yep its true, welcome to the world of fix it again tomorrow (or as i prefer to say ferrari in affordable trim, but thats just denial)

the wiper fault does sound very much like a relay problem. i'm confident you can easily fix that with a scrapyard part.

the engine management light issue cant be related. the wiper circuit is independant of the ecu, and when the engine managenent light is illuminated it means the ecu has noticed a fault. that means a sensor is either no longer wokring or has returned an out of range value. there are many possible causes, on the 1.6 its often injector fialure, coil failure, lambda sensor failure, crankshaft or camshaft sensor failure, a bad earth strap connection and literally hundreds of other things. a diagnostic check will often identify the exact fault, but it may be better to wait and see what happens. often the fault will go away, also try some redex in the fuel tank. and let us know what the symptoms are, when does the light come on (all the time, on acceleraiton, when slowing down, only at high rpm) and does the engine lose power or run rough when the lihgt is on (or even all the time?)
 
Well, the light disappeared after a day and I haven't seen it since. It had been on whenever the engine was running. More suprisingly the wiper problem fixed itself too, after 5 days.

You really do need a sense of humour driving a Fiat don't you... It seems with this thing that there will always be something wrong somewhere.

Thanks again for your help.
