my drivers side rear brake light not working so i changed the bulb but still not working. can any 1 give me some ideas what it could be thanks

 

fuse or faulty wiring in the bulb holder or cluster somewhere

 

spoiler brake light not working as well
tryed all fuses under bonnet

 

is there any other fuse boxs in the car accept under the bonnet

 

On classics and early cars, there is one under the coin tray, driver's side lower dash: you have to lower the coin tray, then pull it right out.

And it REALLY helps if you post what car........

However, if it were a fuse, it would likely put all three lights out, so..........

First off, see if you can trace which wire comes from the brakelight on the worlking side. Then trace it back towards the top of the boot and across, where you might find the wire from the non-working side.
It could be a poor connection, bad earth, short circuit on the spoiler brakelight, corroded connectors, broken wire, etc.

 

thanks for the help not too sure how i fixed it but after pulling and pushing the wires it now works

 

Bad connection, then.

I'd be inclined to look at any connections and check for corrosion.
