Hi, I've recently replaced the rubber steering coupler in my 2011 Hyundai i30 (this is a common problem). Simply put; disconnect a range of electrical plugs on the steering column, undo bolts/nuts so that steering column comes down, open power steering motor and replace coupler, then put everything back.
After doing all this, my brake lights are on permanently when the ignition is on. When the car is off (engine off and ignition off), the brake lights are off (so that's good). When I then press the brake pedal, the brake lights come on as they are supposed to (this to me suggest the brake switch at the pedal is OK - but I could be wrong). But then, as I said, once ignition/engine is on, brake lights are on all the time, whether brake pedal is pressed or not. I checked fuse and relay (if I got the correct ones) anyway and they seem OK.
Hope anyone has any thoughts? Thanks
