Rory Posted March 14, 2007 Share Posted March 14, 2007 My stupid horn has stopped working! I checked the horn push on the steering wheel which seems to be connected ok. I had a look in the fusebox, and theres some sort of fuse/ relay block for the horn. I couldnt see how it comes out to check it though, do you simply pull it? I didnt want to break anything. Anything else I should check? Link to comment Share on other sites More sharing options...

Rory Posted March 14, 2007 Author Share Posted March 14, 2007 Well I'm assumed it was bought as an aftermarket addon, unless these were an option from the factory ? It has a momo wheel, which Ive seen on quite a few Supras... when I took the centre section off I was suprised to see a little TRD logo horn push in the centre of the wheel underneath.

Big Ads Posted March 14, 2007 Share Posted March 14, 2007 Close up pics of centre section would help mate, could just be that the MOMO cover doesn't allow you to press far enough to activate the horn. Link to comment Share on other sites More sharing options...
Rory Posted March 14, 2007 Author Share Posted March 14, 2007 Nah it does ... it worked fine before but has stopped working now. Took centre of wheel off to check it today. Link to comment Share on other sites More sharing options...
Sheefa Posted March 16, 2007 Share Posted March 16, 2007 You sure you haven't blown your normal fuse in the engine bay mate, under the fuse cover, and not the relay (larger one) ? It's a 15w one ,blue, and controls the hazards too. Pop your hazards on, if they don't work, that's your most likely problem. Mine has gone a few times with an aftermarket horn.

Graham S Posted March 16, 2007 Share Posted March 16, 2007 Have you tried a multi meter on the actual horn itself? See if you get 12v when its pressed, that way your eliminating everything on the way there! Link to comment Share on other sites More sharing options...
Rory Posted March 18, 2007 Author Share Posted March 18, 2007 Well I checked the fuse, and its fine. Will try a multimeter on the horn in the next couple of days ( off work tomorrow but the weather is artic just now ! ) I've had a brainwave though. My alarm is spliced ( badly with tape, not by me lol ) into the loom, and it must have a connection to make the hazards flash when the remote control is pressed. I will check these connections out!

Mas Posted March 18, 2007 Share Posted March 18, 2007 dont forget that 99% of after market steering wheels need a negative wire connected to the bosskit, you may want to check that Link to comment Share on other sites More sharing options...

Rory Posted March 18, 2007 Author Share Posted March 18, 2007 After reading as many threads about horns as I can , I now suspect something wrong with the wiring at the steering wheel boss. The self cancellation of indicators doesn't work properly either on mine... one direction works but not quite at the points youd want it to , and the other direction doesnt seem to work at all Link to comment Share on other sites More sharing options...
Pot Posted March 18, 2007 Share Posted March 18, 2007 I'd suspect it was that too, when I fitted my Momo wheel, the boss didn't have anywhere for me to attach the earth wire, I ended up creating a point for it to go onto... I noticed the indicators didn't always cancel too, but I can't say for sure if they always did before, luckilly I've driven enough old bangers in the past for me to be used to cancelling them myself...

Mas Posted March 18, 2007 Share Posted March 18, 2007 I must have fitted over 100 steering wheels by now and they mostly are the same with the bloody horn business Link to comment Share on other sites More sharing options...
Wazz72 Posted March 18, 2007 Share Posted March 18, 2007 Its less embarassing if your horn doesn't work anyway. Supras horn is more of a wine than a beep. Link to comment Share on other sites More sharing options...
Rory Posted March 18, 2007 Author Share Posted March 18, 2007 Had another quick look behind horn push ... and it has a wee TRD horn button - Behind that you can see the red wire with blue end that goes onto the horn button... what Id like to know is what the other white connector thats sitting there is for ?

Big Ads Posted March 19, 2007 Share Posted March 19, 2007 On mine one of the wires that comes from the horn button has to be earthed for the horn to work. Link to comment Share on other sites More sharing options...
