Default A/C problem - Compressor lock

hey guys,
I have a problem with my a/c system.
I have a LS400 1998, with navigation, and AC button is blinking on the screen. When I push AC, the compressor kicks in for ~2 seconds and turns off.
I pulled the codes and they are:
B1421 - solar sensor, pass side
B1422 - compressor lock
B1424 - solar sensor, driverīs side

I assume solar sensors are ok, and the compressor lock causes these codes.
I did some research, but not much info about that B1422 code.

All I found out is that it may be a compressor sensor, that is located on the back of the compressor. If it is bad, it doesnt send a signal and the compressor turns off.

Today I tried to take it off, bot there is absolutely no space there.
So if anyone had some experience about that code, please help.

Thanks !!!!
