take a speaker that you konw works and connect leads from it to the leads of the "bad" back speakers, if the good one works--it is the speakers not the amp.
i did this to trouble shoot mine. both back speackers went out.
you can replace the mast. the plastic "wire" in the mast breaks causing it not to work, even when the motor is functioning ok. lexus has a new mast for about $45.00. someone said that pep boys has a toyota replacement for about $25.00.
hope this helps.
i had the same problem. the back speakers are 4.5" and are mounted in brackets.
you have to remove the back seat and the back deck lid to get to them. i replaced mine with infinity speakers.
can anyone tell me how to remove the leather cover over the emergency
brake handle? my dash brake light flicks on and off occasionally
till i push down on the emergency brake handle and i think that
maybe a switch under the cover needs adjustment--am i right?
go to autozone and order them for about $25.00 per "trunk lift"
as they are called-- the part # should be 95270--this is for a
1995 sc400 but the lifts should be the same. have autozone check that.
good luck
the rear speakers are 4 1/2" and require removing the back deck to get to them. this is not a difficult job
but a time consuming one. you have to remove the back seat first. you can test your amp by using a "good"
speaker and touching a hot wire to your "bad" speaker lead ins, if the "good" speaker works then your amp is ok.
you can do this from the trunk without removing anything. i had both of my back speakers die at once and did
this procedure to find the problem. its wasn't my original idea but a good one.
just curious but my 95 sc400 has a cabin filter unit mounted below the glove box. does the sc300 not have the same unit?
i pull the plastic panel below the glove box and remove two wing-nuts to get to the filter. i had the same odor problem
till i replaced this filter.
t0ked is correct. The 4" rear speaker sit in a plastic pod. I removed mine yesterday. The paper cone was competely gone. The sun had dried it to dust. The hole in the metal rear deck is 4 1/4 inches in dia. and the span across the specker bolt down holes is 7 inches. I am going today and find a speker that will fit the precut opening. I will post the size that fits --hopefully-- tomorrow.
YEAH, MY 10 YEAR OLD DAUGHTER THINKS THE FOLD-DOWN CUP HOLD IS COOL. BUT EVEN SHE WONDERS WHAT IT CAN ACTUALLY HOLD.
YOU WOULD THINK LEXUS ENGINEERS WOULD BE MORE PRACTICAL THAN THAT. OH WELL, IT'S ONLY A SMALL PRCIE TO PAY TO DRIVE AN SC.
DO NOT KNOW. BUT I AM GOING TO THE LEXUS DEALER NEAR ME TOMORROW. IF I REMEMBER, I WILL ASK THE PARTS MANAGER WHAT IT COSTS.
YOU COULD TRY TO FIND ONE ON E-BAY. ACTUALLY I NEVER USE MINE BECAUSE THE FLIP DOWN HOLDER WILL NOT HOLD ANYTHING BUT A 12 OZ. SODA CAN OR SMALL COFFEE CUP. ALL THE CONTAINERS YOU BUY TODAY :P ARE TO LARGE FOR ANY OF THE CUP HOLDERS IN AN SC OR IT SEEMS THAT WAY TO ME.
DON'T KNOW ABOUT LEXUS BUT MY G.M. CAR HAD A SIMILAR PROBLEM AND IT WAS THE SPEED SENSOR CONTROL THAT WENT BAD.
THE CAR WOULD NOT SHIFT RIGHT AND THE TACH WOULD JUMP . OCCASSIONALLY, IT WOULD WORK FINE THEN ACT UP AGAIN.
IT COST ME ABOUT $180.00 TO GET IT FIXED AT A G.M. DEALER. HOPE THIS HELPS--GOOD LUCK LETS US KNOW WHAT'S WAS THE PROBLEM.
HOW DO YOU "GET" TO THE TAIL LIGHT BULBS. THE WARNING LIGHT CAME ON FOR A BLOWN TAIL LIGHT BULB. BUT LOW AND BEHOLD WHEN I OPENED THE TRUNK, THE BULB RECEPTICALS WERE NO WHERE TO BE FOUND. I AM GUESSING THAT THE TAIL LIGHT LENSE COVERS MUST BE REMOVED BY LOOSENING THE SMALL NUTS ON THE SCREWS STICKING THROUH THE REAR OF THE TRUNK. AM I CORRECT?
AMP ON SC400 IS UNDER THE CD CHANGER IN THE TRUNK.
MY REAR SPEAKERS RECENTLY WENT OUT -WELL NOT COMPLETELY-IF I PUT ALL POWER TO THE REAR, I CAN FAINTLY HEAR THEM. I WOULD BET THAT IT'S CAUSE BY A PARTIAL AMP FAILURE. I CAN'T IMAGINE THAT BOTH REAR SPEAKERS WOULD GO OUT AT THE SAME TIME. HAS ANYONE "FIXED" THIS PROBLEM YET?
