vyhanh Posted August 31, 2004 Share Posted August 31, 2004 Hi, I have noticed that lately, my son's 91 LS400 has this symptom: When the ignition key is turned on (but not to start the engine , only to light on the dashboard), after the soft warning musical chime is done, there is a slight click click click sound which finishes about 1 or 2 seconds after the chime. What is it? Thanks VH Quote Link to comment Share on other sites More sharing options...

vyhanh Posted August 31, 2004 Author Share Posted August 31, 2004 No, I am sorry. It comes from the front ! Quote Link to comment Share on other sites More sharing options...
VBdenny Posted August 31, 2004 Share Posted August 31, 2004 Try some stethoscopes. I bought one at Sear's for about ten bucks. It has a long metal probe and it is very sensitive. The get someone to turn the ignition off and on and track it down. They are pretty cool to use as you hear all kinds of weird noises. Probably a relay or cirsuit breaker for something. I think I had a feul pump one time that made the noise too/ Good luck Vh Quote Link to comment Share on other sites More sharing options...
