I have a 2005 freightliner century class s/t 120 and I am trying to locate the 2 ac sensors but I cant find them. Anyone that could let me know, I will appreciate it a lot.
The the pressure switches are found on the air conditioning pipes, on both sides of the air conditioning compressor. On the low-pressure side (smaller pipe), you can find the low-pressure AC switch, and on the high-pressure side, the opposite switch (large pipe).
