1990LS400 Posted October 13, 2008 Share Posted October 13, 2008 Yes, the broken wires in the left trunk hinge can cause this problem. Here are some instructions: http://www.lexls.com/tutorials/lighting/bulbout.html I had to fix this on the 90 LS I used to have. Quote Link to comment Share on other sites More sharing options...

I have found Rich Industries to be a good place for small parts like that. Their prices are very reasonable and they usually do not have a problem shipping small parts outside of the Kansas City area. www.rich-industries.com Quote Link to comment Share on other sites More sharing options...
90LS400Lexus Posted October 16, 2008 Share Posted October 16, 2008 the car started to jerked and bucked like a wild horse!!! Gee, sounds like you have a Mustang, not a LS400. Seriously, that sounds bad... hope you get it going right again. Quote Link to comment Share on other sites More sharing options...
