There could be a ground on the body of the vehicle. If this isn't the case there could also be a problem with the relay that go to the indicators.
try indicator relay switch,,its in the steering colum,and its square shaped
Maybe it's because your engine isn't working or your car is getting too old. I recommend you to fix your car.
Yes, when you turn on the ignition the Check Engine light will come on for a few seconds to show you the light is working. It will go out if no problem is detected.
Usually a problem with emission system have vehicle scanned to determine the problem
Even if the indicators are slow the relay should still click on and off. just open the relay box, turn indicators on and remove relays one at a time until indicators stop. The relay is usually a fairly large one. Hope this helps.
check the fuse
The flasher from other answer is what makes the noise and makes them blink which is why I recommended you try replacing
I have a 02 fiesta, its the engine light mines on 80% of the time, this is because the speedo stops working mainly in wet, cold weather but sometimes in the summer, the light comes on then. But if your speedo works fine, it could be a problem with the engine. Just get it checked by a mechanic or on your next service just incase.
can only be a short circuit, broken wiring, bad earth, dirty connections check and try them.
your motor has probably gone, try wd40 on it first thoughtto make sure
Under the actual indicator. There are 5 screws holding the steering column cover together, remove them (all underneath the column) then under the indicator you will see the relay switch (black box thingy) Why do I know? I have a fiesta mk4 and the relay has gone, resulting in no indicators at all.. not even on the dashboard.
Bad socket? Bad Ground? Broken wire?
