Free.51 2,740 Posted September 5, 2014 Gday all my second question for today is does anybody know what would cause the stop lamps in my zl to stop working? I've been trying to figure out the problem for about a week now with no results. I have power at the fuse I've got power at the switch connectors & I have power at the tail lamp sockets when the parkers/headlamps are on I've grabbed a whole bunch of extra switches from pick apart & bought brand new bulbs but still the brake lamps won't come on the tail lamps do though. Is there supposed to be a earth wire from the the tail light panel to the brake light loom? Any help would be awesome thanks- Chris Share this post Link to post Share on other sites
Mr Polson 10,214 Posted September 5, 2014 Could be the trip comp/clock and system test assembly. I had a short in there in my ute and it resulted in no brake lights. Share this post Link to post Share on other sites
Free.51 2,740 Posted September 5, 2014 Yeah I unscrewed the trip computer yesterday thinking that maybe it wasn't plugged in properly but it was, how did u fix your problem mate? Share this post Link to post Share on other sites
BoostedXD 14 Posted September 5, 2014 Often blows the test panel if you have hooked a trailer up or have a short in the brake light circuit. Share this post Link to post Share on other sites
Free.51 2,740 Posted September 5, 2014 The test panel/ clock works fine Share this post Link to post Share on other sites
Mr Polson 10,214 Posted September 5, 2014 I replaced mine. Â Can also be caused by a faulty cruise control computer. Once again, replace it to fix. Share this post Link to post Share on other sites
Free.51 2,740 Posted September 5, 2014 Is the cruise control comp. the actual thing with the test panel & clock? Or something else thanks again Share this post Link to post Share on other sites
Mr Polson 10,214 Posted September 5, 2014 Its the little box thing behind the clock/test panel. Share this post Link to post Share on other sites

Free.51 2,740 Posted September 11, 2014 Seems like everyones having trouble with their brake lights/cruise control/trip computer lately anyway I bought another cruise control unit from pick a part plugged it in & still no brake lights so now I'm gonna unplug the test panel and jump a wire to the 2 green/red wires & see if that works hopefully it does & then I'll know that there's a fault in the test panel & go & buy another one of those. Funny thing is I had a spare one couple of months ago from when I stripped an fe for parts but sold it on gumtree oh well. Share this post Link to post Share on other sites
Free.51 2,740 Posted September 12, 2014 I unplugged the test panel/trip comp. And ran a wire between the 2 green/red wires & the brake lights work thank fook for that but when I plug the test panel back in they don't work so I guess it's time for a new test panel. In the mean time I'm gonna pull this one apart & have a look inside. Share this post Link to post Share on other sites
