  1. I fear my SC400 is near the end of the road. I just returned from a week long vacation and all the sudden the following electrical components are not working regardless of what I do: Power Seats, Windows, Steering WheelStereoClimate Control UnitDashboard (When set to ON)But these electrical components ARE working like normal: Door ChimeHornLightsThe battery and alternator are both less than a year old and the battery tests out as good. My car was left on a gravel driveway and has been there from last Sunday (6/29) to this evening (7/7). When I left it, it would start just fine and all components were operating normally. Regardless of where I turn the car key now though, thedoor chime doesnt stop. Nothing lights up and I hear none of the typical fuel pump/preparation noises the car makes in the ON position. I've spent all day researching what could be wrong and followed some suggestions. I tried using a valet key and that made no difference. I checked the 7.5amp fuse #4 in the driver panel which is responsible for the starting system and it was OK. Made sure the car was in gear, attempted a jump start...nothing. The only audible response I got was when I tried the door locks. They stopped working a long time ago, but have always made a noise as though they were trying to lock. They are still making that noise. While I was testing the various components out, my Uncle Gearhead noticed a "electrical burning" smell coming from the alternator area. I'm at a loss for what could be wrong. Any ideas what I can look into? Thanks for your help in advance!
  2. Hello everyone, I'm looking for some input on how to best install an A/C compressor to my '94 SC400. I haven't done this before. The compressor I'm installing is OEM and was pulled out of a fully charged A/C system on a '97 SC400. I'm replacing my compressor after some research into my blinking A/C light (as seen here). I figured all I had to do was take out the junk compressor and put everything back together with new o-rings. But now I'm under the impression that the entire system needs to be pressurized with a vaccum and professional guages are needed to make sure everything is in order. It's also been suggested I get a $15 A/C Dryer from NAPA to replace the old one. Finally, I've been told that I can find potential leaks in other areas while I install the compressor using a blacklight. I think there's a big one somewhere since the junk compressor had refrigerant in it. In any case, I'm debating on how best to go about things before I start installing the compressor. I've attached the pages I'm following in the SM to this post. As always, thanks for your help in advance. AC Compressor SC400.pdf
  3. Power Steering Leak!

    Just wanted to thank you for this suggestion. I think it's going to solve the issues I'm beginning to have with my pump which was just replaced a couple years ago. The car leaks a small amount of fluid after it is turned off and left alone, and I suspect it is coming directly from the pump. The system does not "whine" while in use or act up, but i know P/S fluid bis leaking somewhere because the reservoir needs refilled routinely. Hopefully an O-Ring is all I need, but are there any other things I should be looking for?
  4. Sc400 Transmission Flush

    Hey everyone, another update. My SC400 now has ~232k and it has been almost 4 years since we did the transmission flush. This original transmission Lexus thought was dying is still in the car! On a routine inspection today though I found the T4 ATF fluid needs to be replaced again. It's not red, rust brown, brown...it's black. My dad took a look at it and we've decided to do something about it this week. Looks like some of my college graduation money is going toward preventive maintenance on what has been a pretty good college car. :) Results: Flushed 10 quarts OEM T-IV ATF through the entire system, 2 at a time. I thought it would still be somewhat black when we were all done, but the fluid now is still a clear red after driving it around a couple of weeks. Transmission shifts smoothly and I haven't had any problems with it so far. So, for me at least, the full T-II to T-IV replacement we did back in '07 (all at once rather than 2 quarts at a time) has led to no repercussions. For all I know though, it may have originally had T-IV in it when I bought it...
  5. Afternoon LOC members, I have a Nakamichi amp and P/S pump up for grabs. They're both from my 1994 Lexus SC400. The amp will not work as-is, but for somebody who repairs these it may be useful for parts. It sustained water damage from a car wash (through that overflow hole) and blows a fuse when it is plugged in now. The amp includes the mounting bracket. The pump has a small leak. It looked like it began due to a failing O-Ring. Fortunately, it was not significant and the leak avoided my alternator. I was pressed for time when the leak began though and had to buy a new one immediately. I think it may be just fine with a resealing kit from Toyota, and this why I held onto it. Asking 120+Shipping for both through Paypal. Please PM me if you are interested. Thanks for looking! - Brandon
  6. 97 Lexus Sc400 With 187K One Owner

    I would probably offer somewhere in the low-mid 4k range if he had maintenance records and the interior was in good shape. I got my '94 three years ago with 188K for under 4k after title and taxes. The seller wanted 5500 at first, but no one was offering to buy it.
  7. 93 Sc300 Transmission Problem

    Just throwing it out there...have you checked the transmission fluid level before you've driven it by any chance? I recall having a slipping problem of my own after performing a transmission flush, and it was instantly fixed by adding a little more T-IV fluid when I got back from my test drive. If your trans acts up every single morning, maybe the temperature outside in the morning is influencing things. If it's below freezing, maybe the liquids are getting thicker and leading to your problems.
  8. Complementing Yokohama As430s

    My plan then was to get these two for now, then buy four later and sell them. Just can't do that when you're a college student who is now in between jobs. :whistles: I'm afraid I have to do the responsible thing and continue using them.
  9. Hey guys, I'm officially convinced Winter is over around here, and I'm looking to get the snow tires off my car very soon. I'm in the market for two new tires to go with the AS430s I got back in '08. Turns out my local NTB no longer stocks them...so I'm shopping around. What would you get?
  10. Cold Start Failures

    Alright, here's an update. I followed grnsc400/CR's advice and got an Everstart Maxx battery based on its 700 CCA and positive warranty reviews. I didn't have a single problem starting through the deep freeze here in the states. Looks like I'll be seeking out multiple opinions the next time something acts up. Thanks again for all the help, everyone.
  11. Cold Start Failures

    Don't have a multimeter, but I found out this morning after making some phone calls that my local NAPA and Advanced Auto Parts offer free testing with theirs. Just got back from having tests done on the battery, alternator, starter and charging system at both places. Much more in-depth results than the "A-OK" I got from Auto Zone! Turns out my suspicions have been confirmed...the only problem I have is that Autocraft battery, which measured 631 CCA at NAPA and 544 CCA at AA. Apparently, it's supposed to be close to 875. No wonder my SC has been struggling. What stinks though is that the battery was purchased at AA on 12/7/06, so it's out of the 36 month replacement warranty. <_< It's prorated for an additional 47 months, but I don't think I'll be buying another Autocraft battery based on the problems outlined in Eatingblacktop's link. What batteries do you guys use/recommend? My poor car has to endure startups below freezing temperatures on a regular basis during the winter, so I'm thinking I may need something like a Redtop Optima... Thanks for all the help so far, everyone.
  12. Cold Start Failures

    Is there a way to do this at home, by any chance?
  13. Cold Start Failures

    Hey everyone, I'm in need of your collective expertise again. The temperature is dipping below freezing around here, and my '94 SC400 isn't starting up on its own anymore. I suspect it's the alternator and battery, but after having both of them tested at my Autozone they passed. The test seems to be reliable; I had my '98 4Runner checked at the same place a couple months ago, and the OEM alternator in it finally needed to be replaced. I replaced it along with the battery, and she starts just fine again. The battery warning light on my SC's dash lights up at startup and stays off whenever I drive. The battery is an Autocraft Titanium and was purchased on 11/2006. The alternator was purchased on 6/2006. Assuming the test is accurate and both are all right, what else should I be checking? I didn't have any luck finding common trouble spots on the forums.
  14. Sc400 Transmission Flush

    I don't know how much help I can be here, because this was one of the first things I addressed with my car and the memory is hazy on how I took care of it. When I did flush was done back in 2007, I decided to do a full flush instead of the progressive approach at the advice of my father. We did this to get it running on T-IV only. I also took the trans pan out to clean out the magnets inside thoroughly. I think I replaced the pan because we wanted to get rid of as many contaminants as possible. I don't recall there being any additional filters beyond those magnets I worked with... In any case, my tranny has been fine since that flush. I've driven ~32K (now at 223k on the car) with no noticeable slip-ups or problems.
  15. Power Stering Leak

    Based on my own experiences, depending on who previously owned your car (if it wasn't you), the lines may have been changed and could be the only thing causing your problem. I don't know how much this can help you, but I attached a diagram for my own 94 SC400 that was used to diagnose my own PS problems a couple months back. We pinpointed the leak to a single hose (shaded part 44416 in the diagram) that the previous owner tried to fix and did it myself...fixed the entire system! Unfortunately for me, a new leak has been discovered closer to the pump and we're still trying to see if the pump is responsible or not. I'd definitely take a look at the lines before replacing the pump, if you haven't bought a pump already. SC400_PS_Diagram.PDF
