LS400inCA

Sounds like an expensive repair. Any idea as to whether it is an issue I should take care of immediately to avoid even more expensive repairs down the road? I've put $1600 into it in the last month and would love to wait on any more major repairs if I can, but I know it doesn't make sense to wait if it will only cost me more in the long run. Your input is really appreciated!

Thanks for the help! I'll start with a check of the filter. Amazingly, all day today it has been working perfectly. So I'm hoping it is just a loose wire.

I just took my 1996LS400 to a mechanic to fix a knocking sound that I hear in the front right of the car when I go over a speed bump or a dip in the road. He replaced the front strut rods and bushings, but the noise is still there. Any suggestions as to what the problem might be?

I am the proud new owner of a 1996 LS 400, which I love, except for a new problem that just developed with the a/c unit. When I turn on the A/C, whether in Auto Mode or Manual, it blows cold air on high speed for a few seconds, then low speed for a few seconds, then high speed again. It does this repeatedly and is the same whether I put it in Auto or Manually adjust the air. The air is still cold, but I need to regulate the amount of air that is being blown out of the vents. Any suggestions as to how I might fix this problem?
