neil nz Posted March 5, 2009 Share Posted March 5, 2009 Help My 90 ls400 suspesion pumps up realy high and hard but not all the time .Sometimes its the front and sometimes the rear and sometimes both.Have pulled the batterie played with the on off switch in the boot and after a while it will reset to normal. Then after a few days the pump will operate with the key out and pump up one end or the other or both.Makes it hard to drive and also get a power of gref from my mates driving around with the suspesion all jacked up.

SKperformance Posted March 5, 2009 Share Posted March 5, 2009 sounds like a pressure switch issue, no clue where or how to fix it. Quote Link to comment Share on other sites More sharing options...

cubaski Posted June 9, 2010 Share Posted June 9, 2010 Neal, I have been groing through the same with my 92 Ls400 and was wondering if you were finally able to find out what was the problem causing the suspension to act this way. Could you give me some pointers? Thank you Quote Link to comment Share on other sites More sharing options...

Hello sk, I've been trying to resolve a power issue with the fog lights on my 92 ls400. I tested the light conducters and fouond no power, I then tested the fuse that's under in the cluster pannel and theres power but not circulating through to the lights. Is there a breaker or a wire that this particular model suffers from being replaced or something? I appreciate it if you can point me to the right direction. Thank you Cubaski Quote Link to comment Share on other sites More sharing options...
SKperformance Posted June 17, 2010 Share Posted June 17, 2010 cuabski make a new thread from this one on its own. I don't own a 92 but it does have a fuse and is activated by the stalk. Quote Link to comment Share on other sites More sharing options...
