LEXUS GS430 2001 - HELP

Hi, please can anyone HELP and advise !! I don't want to take the car to lexus dealer.... Not worth it

Is it the ecu???

Issues: ON GOING FOR 7 MONTHS NOW. CAR IS OFF THE Road and I'm frustrated as I don't know what to do.

Strip and scrap the car will be the next stage 😯😢😢😭

All this started one day... Left car at airport for one week in car park. Came back and the car started but on way home no HEATING!! Radio worked Inc sat nav... Lights stopped working... Started to loose power and RECOVERY Home 🚗

loosing charge very quickly on NEW BATTERY. Charged back up 3 TIMES once the battery is fully charged... The car drives well but looses electrics and lights. ____Yes it looks like alternator!!! ____The auto electrician said its NOT? WHAT'S GOING ON

At one stage all windows stopped working... Before I took it to auto electrician

HEATING NOT Working AT ALL... (since all the issues started happening) !! THE FAN WORKS FINE AND THE REST WORKS. I HAVE BOUGHT 3 SAT NAV RADIOS..... its NOT a faulty sat nav radio heating unit faulty 100%

All fuses checked

It blew my original heating/radio/heating head unit 1st one stopped working!!! I bought a couple more replacements on ebay lol 😀😀

It's been to an auto electrician... Spent £1500 having checks...maybe the guy had little expirience with these cars!!! We changed the heating solonoid component from LEXUS dealer

Do I get the ECU checked??

Ive been told to send it to the dealer. 4 months later they will fix it at a cost of £4000 ))

Why?? Does anyone know any secrets to these cars ⚡🙂⚡🔐

Any advice would be appreciated guys!!!!!! Please please

Thanks

Wow, that is a lot of $$$ spent not to have your issues fixed.
The original symptoms you mentioned sounded like a bad charging system. I would replace with a new battery, alternator and check all the wires and connections for the charging system. That is, the battery cables and the grounds to the chassis/engine block.
Once you get the charging system going you should be able to better troubleshoot the other issues.
Good luck with your repairs.

If you're loosing charge on a new battery that points to your charging system...grab a multimeter ($10) and with the car running check and see if you're getting 14v from your alternator.

What's the voltage when the car is running?

Low voltage on other threads show that really weird things can happen.

I'd replace the alternator at this point, even if it is "tested good". We've had too many times with Toyota/Lexus cars, that we'd pull the alternator, have it tested good, still have an issue, then have the issue resolved with a replacement alternator.
