extreme Posted July 21, 2003 Posted July 21, 2003 hey guys... need help... i got a 93 sc400..... car was working fine... until last week.... first the A/C won't work unless i set it to the MAX.. the coldest setting... then the cold air will work.... when i turn the unit up to just even one click... hot air blows??????.... then on thursday i think the Valet ppl forget to turn off my headlights and it drained out my battery cause on the way home i noticed the red battery light turn on... but after awhile it will go away.... then when i'm idealing.. it come back on...... then friday nite went to eat... and notice my power windows were going slow.... and then when i turned off the car.... and tried to start... it would.. just made a ticking noise.... then i come back and try to jump it... it won't make the ticking noise..... nor will the power doors and the trunk release button work....i thought it would be my after market alarm... so we took out the brain and disabled the alarm.. but still the power doors and the trunk release will not work????? and the damn car still won't start with a new battery... did all the test...12V..... relays...etc... works... my only guess is my car can't start cause of maybe a bad starter??? but still have no clue about the doors and trunks.... ANY SUGGESTIONS?????
SKperformance Posted July 21, 2003 Posted July 21, 2003 your alternator is shot get it checked and replaced it is a common problem also look at the power steering pump to make sure it is not leaking on it causing the problem for the a/c problem might be in regards to the flap that controls the flow of air do the a/c diagnostic test and it should come up as what the problem so do a search and it should show a post for how to get the codes and what tehy mean
UCF3 Posted July 21, 2003 Posted July 21, 2003 I would also try cleaning the power supply and the relays. My experience with the clicking noise was, the connection to the battery wasn't connected throughly. Are you having any problems turning the engine?
extreme Posted July 21, 2003 Author Posted July 21, 2003 when i turn the key to the start positon... nothing is happening.... but when we did the wire tests... the wires are fine... just not starting up the car... so u guys say it's the alternator??? and that is linked to the power door locks and trunk button...???? cause when i did the test on the wires... i can release the trunk.... BUT not with the switch.. only when i do the testing... from underneath the dash with the wires.. i can activate it to release the trunk... and yeah... i did notice some leakage on the power steering... also... so u don't think it's the starter at all???? cause i did have a aftermarket alarm system... Audiovox Pretige... that i could automatic start the car with from the alarm remote......
UCF3 Posted July 21, 2003 Posted July 21, 2003 Actually, we can't say anything. We don't have your car infront of us. Are the rest of your electronic instuments working, radio, dash, pw, lights and so on? I think it's the battery relay, but it could very well be an alternator problem or something else. There is something my friend did with my SC when i disconnected my HID relays. He hit the bottom part of the block--on the left side of the car. I think he called it "rocking" the block. Try hitting the bottom part of the block, just above the Pan with a stick end of a broom stick. It may do the trick. Don't forget to check those relays and tighten the screws. If that doesn't work, you might need to tow it to Lexus. good luck.
sandstone400 Posted July 21, 2003 Posted July 21, 2003 Check for a 7.5 amp fuse located on the inside fuse box. It controls the alternator recharge system. My car ran fine until the battery started to drain. First, the radio went scratchy, windows slowly died, trunk wouldn't release...etc. It's like systems just barely worked off of whatever voltage it could get. There are a couple of fuses in that system! It was better than the new alternator and battery the parts place was trying to sell me AFTER they checked out the system themselves.
Sc400 Tuner Posted July 21, 2003 Posted July 21, 2003 lol! Rocking the block?? Is that like kicking the tires when you by a new car? You must be joking.
extreme Posted July 21, 2003 Author Posted July 21, 2003 so after you replaced that fuse... everything worked ???? thanks for all your help guys... i just towed my car to my mechanic.... i trust him... he does all of our cars and show cars..... J.E.R in Garden Grove, CA...... let's see what he comes up with...... but i really appreciate everyone's input...... i'll let you know how things are going.... THANKS AGIAN EVERYONE...
UCF3 Posted July 22, 2003 Posted July 22, 2003 lol! Rocking the block?? Is that like kicking the tires when you by a new car? You must be joking. No, I'm not.
SKperformance Posted July 22, 2003 Posted July 22, 2003 i have a friend with a ferrari tesstarosa and as he tells me ask any one of those owners and they carry a hammer in the small trunk just for that reason of the sticking starter
SPORTcoupe300 Posted July 22, 2003 Posted July 22, 2003 they carry a hammer in the small trunk just for that reason of the sticking starter LoL. That's hilarious. Why not just go back to the old crank in the front of the car. Bust out the big old bar and start spinning the engine by hand. So do they hit the actual starter housing? or just the solenoid?
extreme Posted July 22, 2003 Author Posted July 22, 2003 okay... my mechanic fixed my car..... thank God it wasn't the starter... cause that would have been a !Removed! to get too..... was an electrical problem with my car alarm system.... I have the Prestige 995 and it has an automatic start feature.... so something was wrong with the alarm.... DAMN IT.... I thought i checked it all... anyways...... i also replace the alternator cause it was bad... but you all know... it is a common problem anyways...... thanks everyone for your imput again.... oh.. by the way.... for everything i spent $295.00 ... not bad huh???
SKperformance Posted July 23, 2003 Posted July 23, 2003 not a bad price at all for everything now get rid of the prestige alarm and you will be perfect its like putting a skoda part on a lexus they make crap in regards to the hammer i am pretty sure they hit the solenoid as it is the part that sticks but i never got into the exact enginneering of the hammer technique,or it ounce weight lol
AWJ Posted July 23, 2003 Posted July 23, 2003 As far as the starter thing goes - the hammer will work on the solenoid or the armature. A dead spot will get offset enough by the hit to free the armature up or bring the core of the solenoid to contact depending on the location of the calculated blow. Another method is jumping the poles across the starter solenoid. But it is key to make sure the car is not in gear and to wear gloves or you'll get a decent kick of juice through your body if you are not careful.
SPORTcoupe300 Posted July 23, 2003 Posted July 23, 2003 Hehe. Been there done that. If you think 12 Volts isn't all that much, you're terribly wrong. Quite a hair-raiser. Just make sure you don't touch anything else with that live wire if you ever have to do it. =)
extreme Posted July 23, 2003 Author Posted July 23, 2003 i bought the car with the alarm system.... it wasn't my choice... but if it's already on there...... might as well have fun with it.... hahhahah..... anyways.... I've been looking for Soarer emblems or any JDM stuff.... I check Ebay all the time... any good websites besides takakara....
SKperformance Posted July 24, 2003 Posted July 24, 2003 oh yah i fogot thanks for the reply on what was wrong
coolfire Posted July 27, 2003 Posted July 27, 2003 Hi, gotta add to the hammer aspect of this string. I had a Jaguar XK-150 and used to carry a hammer up front in order to pound the floor boards in front of passenge seat to get the car running again when the electric fuel pump, located under that area, would cut out, stalling the car at inconvenient times. Brought some strange looks from passenger, but worked. Also, I miss the crank which I had on the Truimph TR-3. Used many times for starting. :)
