Question

I have a 2005 Lexus RX330. My A/C stopped working while I was driving. I noticed the A/C button flashing. I checked the freon in my compressor, and it was good. I checked all my fuses & relays, all good. I have a code B2124 flashing on my dash. What does that mean?? How do I fix this issue?

Answer 1

B2124 this is for the central lock system, and it is not for the a/c system. If the A/C light is blinking , it means the a/c is inoperative. This can be from a a/c clutch . or the compressor, to even the pressure switches, There is also a TSB that may be what you are facing. TSB# EL003-06. titled Abnormal function of A/C and combination meter. what this repair does is replace the junction box with a improved junction box.
