Indicator relay clicking

[H15DTL]

Hi guys my indicator relay is constantly clicking when driving, noise is coming from behind the hazard switch above the stereo.. Changes noise when indicators are on but then goes back to constant clicking it's driving me mad.!! Anyone had this before.. Is it just relay nackered..??

This is more likely caused by a problem with the indicator switch assembly, not the relay itself. It can be caused by corrosion of the switch contacts or just a build up of muck. Worth trying a squirt of WD40 into the switch, near the base of the indicator stalk. If this doesn't work, try removing and cleaning the switch contacts. You might get lucky, otherwise probably a new switch assembly needed.

Was wondering about that as it clicks sometimes when steering to. I'll have a look later cheers

i had a replacement relay which would constantly click unless indicators were being used lasted about 2-3 days then the relay burnt out. little bit of panic with the smoke from the dash but no damage done. i would advise against running the car whilst its constantly on

Had this exact problem a few weeks a go. Try giving the indicator switch a good clean (the bit between the stalk and the steering column). I stuck some electrical contact cleaner down there, gave it a wipe and put a little wd40 in there, problem solved.

IPA, http://www.maplin.co.uk/p/isopropyl-alcohol-400ml-re79l sprayed on a cotton bud is the best thing to clean the actual contacts with. It cleans well and then completely evaporates without leaving a residue.
It can damage/discolour some plastics though and being pure alcohol, it's extremely flammable and burns with a near invisible flame, so a bit of caution is needed when using it.

Yup, WD40'd my hazard light switch area at the beginning of the year and it worked a treat! Yes it'll be a bit messy but you can always use the residue to clean up the dash board (and it smells nice - kind of)
