sascha 17 Report post Posted January 12, 2012 Okay so a while back my right hand side indicator stopped working. Instead of the indicators coming on, a loud buzzing noise comes from the flasher unit/relay that sits under the steering column. I've tried replacing this with 3 different ones, and today I got a new indicator stalk with wiring loom from Ray and I hooked that up but still no luck. I've got no idea what to check next, as far as I can see there are no plugs unplugged or broken wires. If it helps, when it first started happening it'd happen when I went over a bump or pothole, which made me think it might be a connection that was loose and has now completely unplugged itself? Any ideas on where to look next would be appreciated. Btw, left side works fine. Quote Share this post Link to post Share on other sites
tcbaurpower 5 Report post Posted January 12, 2012 (edited) Might be obvious but did you check the light bulb didnt blow?? Swap it to the left to check maybe. I have had similar issues in the past and it was a the plastic connector was stuffed and didnt complete the circuit properly. I would plug it back in but after a few good jolts it might come loose and again the indicator would stop working. Edit: I think the connector was so buggered the wiring was touching.

sascha 17 Report post Posted January 12, 2012 (edited) But wouldn't that just cause it to tick at twice the normal rate? Edit: I'll give it a go in a sec though and let you know what happens Edit again: I tried swapping bulbs, no luck. What plastic connector are you talking about? The one in the tail lights?

tcbaurpower 5 Report post Posted January 12, 2012 My indicator that was fault was the side indicator, and have had issues with the front too. Try unplugging one or both so you can find which one is the problem. Quote Share this post Link to post Share on other sites
sascha 17 Report post Posted January 12, 2012 (edited) Oh right, i don't have side indicators, only front and back. I'll try that though, thanks E: still no luck. I should also mention that it happens when I push the hazard lights switch too. Anyone got any other ideas? Edited January 13, 2012 by sascha Quote Share this post Link to post Share on other sites
polley 916 Report post Posted January 13, 2012 unplug right hand side bulbs and check with multimeter that there are no shorts in the indicator wiring? if the flasher unit was shorted out it might buzz. Quote Share this post Link to post Share on other sites
tcbaurpower 5 Report post Posted January 13, 2012 Ok, narrowing down the list. If it isnt the bulbs and it isnt the switch, fuse or relay then the wiring is seeming more likely. Follow the wiring and look for any damage, crimping, discolouring and even heat/smoke when you have them turned on. I have had buzzing before and am sure it was when the wires were shorting. The negative is another area to check, it can be fixed tight and still cause issues if the connection surface isnt clean enough. Quote Share this post Link to post Share on other sites

I'll give that a go this weekend, cheers Ok, narrowing down the list. If it isnt the bulbs and it isnt the switch, fuse or relay then the wiring is seeming more likely.

The negative is another area to check, it can be fixed tight and still cause issues if the connection surface isnt clean enough. Fuse & relay all fine, they were the first things I checked. I've followed the wiring as far as I can without taking off the dash and can't see anything out of the ordinary. Will double check the negative in the weekend, thanks for your help by the way.

hotwire 352 Report post Posted January 13, 2012 It will be a short in the R/H circuit somewhere. Look at the extremities first - each end. I would suspect more likely front Quote Share this post Link to post Share on other sites
sascha 17 Report post Posted March 21, 2012 Ahhh can't find the problem! Anyone know a good auto electrician? Or anyone else want to have a go? Quote Share this post Link to post Share on other sites
sascha 17 Report post Posted April 9, 2012 Found the problem thanks to the boys at Mike Barlow Auto Electrical - faulty Hazard light switch! Quote Share this post Link to post Share on other sites
hotwire 352 Report post Posted April 10, 2012 Or voltage drop in the supply line - as confirmed. 3 months to get a simple job confirmed, would have been wise to have it checked at the start & saved frustration Quote Share this post Link to post Share on other sites
sascha 17 Report post Posted April 10, 2012 Yep that's true! Was more like a couple of days to sort it, those couple of days just happened to be spread over 3 months - the car was parked in the garage for most the time while I was travelling and working But yeah in hindsight it would have been easier having a professional check it straight away. Thanks for the help anyway guys Quote Share this post Link to post Share on other sites
