Lexus Troubleshooting Questions? Ask a Lexus Expert
Hello and welcome to just answer, my name is ***** ***** master tech here to help. I annot see or hear your vehicle so I rely on your patience and input to my questions to better help you. I read your notes and have a question before we proceed. I will strive for a 5 star ratting and if I fall short let me know what I can do further. The first thing to do is check all fuses properly at both ends with either a test light oe volt meter. Then check the fuse-able links, these are the square higher amp ones in the use block under the hood. Let me know what ryour results are.
Did you check those links as I mentioned?
are your brake lights working?
Question? Did all these work before you replaced the battery and alternator?
Does the charging circuit work properly now?
does the alternator charge the battery normal 13- 14 volts?
Ok what I would like you to try is locate the window relay and swap it with another that looks the same and try that.
