Howiesjh Posted April 11, 2007 Share Posted April 11, 2007 Hello my car has a problem that I cant figure out. Well at first I noticed my lights would dim when I hit the brakes.. Ok not a Huge deal kinda annoying but i delt with it. But then my car started just turning of all together while I would be driving and this was really scary because I would loose most the brakes and have no more power steering while I would be driving... Well lately its gotten even worse I can drive not even a mile from my house and it will turn of 2 maybe 3 times. Now I finally realized I can turn it back one if I put it into neutral but sometimes that doesnt always work ill have to try turning it back on numerous times before it finally works.. Now it doesnt always turn completely of sometimes it will go till all the lights turn of and the radio stops then catch itself... I was looking at other people post that kinda had a simillar problem on here but there only happened when they turned of there A/C and people said it could be the throttle body could that be my problem?? But mine isnt just turning of when I turn of the A/C.... Any help anyone can give would be greatly appreciated.. THANKSS Quote Link to comment Share on other sites More sharing options...

Howiesjh Posted April 11, 2007 Author Share Posted April 11, 2007 No I dont think so the fluid in the reservoir is still all the way 2 the top but I did just change my thermostat a few weeks ago and engine coolant got everwhere because I didint drain the lines first ... So the coolant might of got into some places... Quote Link to comment Share on other sites More sharing options...

Howiesjh Posted April 11, 2007 Author Share Posted April 11, 2007 Well yeah most likely it is right beside it, but the car still turned of randomley before I did all that. Maybe just not as bad only like 1 a week. Quote Link to comment Share on other sites More sharing options...

Howiesjh Posted April 11, 2007 Author Share Posted April 11, 2007 Do you have any links to show me how to do that? Im not sure what I would do.. The negative Cable from my batter goes somewhere under the engine is that the right cable? And if so is it a very difficult job? Quote Link to comment Share on other sites More sharing options...

The negative Cable from my batter goes somewhere under the engine is that the right cable? And if so is it a very difficult job? That's the one, Just follow it down and disconnect both ends and replace with a heavy duty cable. You might want to contact Sk Performance, Here is a link so you can PM him http://us.lexusownersclub.com/forums/index.php?showuser=715 on these forums, He'll have more info on exactly what to do. He's always willing to help out fellow lexus owners. Quote Link to comment Share on other sites More sharing options...
Howiesjh Posted April 11, 2007 Author Share Posted April 11, 2007 Alright well thanks you, im gonna give it a try I think but when u say heavy guage is that like a type of negative wire you buy from auto store or just like Heavy guage steel that you can buy at Home Depot?

I'm sure you can get it at a auto store, But I think a high end stereo shop might have better products. Quote Link to comment Share on other sites More sharing options...
