Subject: Saab 9000 Hazard Lights - followup

Hi All, There was a thread here a couple of months ago about hazard lights on 9000's only working when the indicators were switched on. I also had this problem at the time on my '96 9000CSE - the hazard lights didn't work unless the ignition was turned on and the right indicator activated. (Bizarrely, the left indicator didn't seem to get it working...) A few other people noted the same problem and Tom/SaabTech noted that he'd had to replace the flasher unit on a car. This alarmed me a bit, but I didn't do anything about until this week, since my MOT is due next week. However, I had a fiddle around a couple of days ago and noticed that messing around with the fuse box (i.e. banging it a bit!) seemed to get the hazards working. Since they've got a unique fuse, I pulled it out, checked it was OK and cleaned up the contact legs (since they were a bit oxidised). Bingo! Fully working hazard lights. I don't know why this caused the symptoms seen - maybe there's another route for the 12V power to get to the hazard lights via the flasher unit only when an indicator is used (I guess I should really find a root cause - since I'm an electronic engineer - but I can't be bothered!) Anyway, HTH. It may not be the cause of other people's problems, but worth checking out before you progress to more expensive solutions. Regards, Gerry, Southampton, UK '96 9000CSE
