I am looking for the lower control arm bushings for my 92 SC400. There are one type listed online made by Ast that sell for $125 for each side. Considering they are just a rubber/composite bushing, I thought that was quite steep. Anyone know of cheaper ones? Also is this a common problem? and are the bushings easy to get out? Thanks for any help.

I have a '93 SC400(Canada model) which has daytime running lights. I just noticed that when they come on which is headlight swich off, park brake off and transmission in drive, then the front side lights and back tailights are also on. I have a workshop manual and looking at the wiring diags I would have to conclude it is a problem in the "integration (daytime running) relay". Can anyone else agree with this or am I missing something simple? Also would it be worth changing as its in an awkward spot, and at what cost? Thanks in advance.

I ran mine "bypassed" for about 8 months but just recently bought a new solenoid. I tried to find the part # but unfortunately I can't find it. Anyhow, I got mine online from http://www.lexuspartsmall.com/ . It was about $138 and if you e-mail them say you need the solenoid that opens/closes the heater valve and they will give you the part #. It is quite a common part to fail. Hence the exorbitant price. Here in Canada the dealer wants $270 for the part. I checked some wreckers yards on the internet but most want $75-100 for it used so I thought I should go new. Good luck.

I think I located the part in question. Is it about the size of a lighter with two hoses leading in to the bottom, and the electrical connection on top? If so, swapping the lines wont' do any damage? Topped up coolant level, nothing. Swapped hoses, nothing. Still looking for options. Yes, that sounds like the part. Swapping the 2 vacuum lines(hoses) won't work. You need to disconnect the electrical connecter and put an ohmeter across the solenoid terminals. If it is open(high ohms) as I suspect, then the solenoid is shot and needs replacing. As a temporary fix and to check the valve and heater core you could plug the two vacuum hoses together somehow and that should open the valve and allow hot water into the heater core.

Mikado Technology Company 1435 Huntington Ave, Suite C San Francisco CA 94080-5974 (650) 615-9966 If you overnight it to them, they will overnight it right back atcha (e.g., send it out overnight on Monday and you'll have a fully functional HVAC back in your hands on Wednesday). They charge $195+shipping. They are legit...got it from Hennessy Lexus Service in ATL. Enjoy! I used them to replace my speedo neddles, and they were very good.

Same happened to mine a year ago. The problem was the solenoid valve that opens/closes the heater valve. It is a small black plastic part close to the firewall on the passenger side engine compartment. It has 2 small 1/4" vacuum lines going to it and an electrical conector. If you unplug it and check with an ohmeter between the terminals you should read about 15 ohms I think. Mine was open circuit so it was dead. A new one cost $138. Its worth about $3 but there you go. Lexus dealers say it is fairly common to fail. Good luck

Yep... they are brand new ones.

I recently bought a new LCD for my '93 SC400 off ebay. I bought it from a guy in California named LEXUS LS400 for about $100. I believe he has a number of these for sale. I was very pleased with his service and the unit. He also has an excellant write up for taking it out and repairing it.*** BUT**** anyone attempting this should have some soldering experience as it is not the easiest job I have ever done. The toughest part is getting all the old solder off the unit. It is quite difficult but certainly doo-able if you have the patience and tools. Anyway, I am very happy with my new one.

Yes, they do but I think they are not on e-bay at the moment. Not sure why.

I have just bought a manual for my '93 SC400 off ebay CHEAP!!!! $7.95 cheap. It is a download from a CD. Seems to work just fine, and the manual looks excellent. Will take a bit of computer time to re-name all the files so that they make sense, but so far looks good. Check it out!!!!!!!!!!!!!!! :D

Look on ebay. They are much less than $400 but you do have to install them yourself.

Thanks for the info. I think I can repair it so I will look on ebay as a used one may not last long.

The Climate control LCD has "bled" and I know its a very common problem. Can anyone suggest a good place to buy new ones and the approx. cost. Thanks, Bess
