The power steering on my 07 LS460 not operating like it should. I have checked all electrical connections which checked out ok. Any suggestions would be appreciated.

 

@Mods, move to LS....

OP, your battery or alternator are likely dying. Any chance, you had a jump lately? A jump with reversed polarity can take out the fuseable link that powers the power steering.
So, tell everything you know here, get the battery and alternator tested at a local parts store. Expect that your thread may be moved to here, the 4th Gen LS general section - https://www.clublexus.com/forums/ls-...2007-2017-178/

GL and report back, the IS folk are pretty nice too!
