hi i have'nt been on the site for a while but i am having issues with the climate control and the clock not working tried checking the fuses, but the diagram does indicate which is which
as mine is a uk model could it be the relay? it all started with me trying to use the cigarette lighter as i wanted to use my portable tyre pump for my front tyre ever since then it has not worked.
could anybody help please

 

The owners manual for the US spec 1992 LS400 says that fuse 14 in the kick panel fuse box is the only fuse for the clock. The same fuse has something to do with the A/C. Here is a link to that part of the manual on the US Lexus website: http://drivers.lexus.com/t3Portal/do...df/6-4_216.pdf

 

I believe that it is your fuse. Your owners manual will tell you which one it is. The same thing happened to me one day, changed the fuse and all better. If you have a test light you can determine what fuse is bad, also. If you are in the UK, go find the Stig and let him take it for a lap, then the clock will be the least of your worries.
