ac system low side nd or high side pressure sensor

[type-r1]

Hello I have been through the ringer with my AC and have finally come to the conclusion that I have a bad high side or low side pressure sensor because my cooling fan does nit kick on with my compressor and I have tested the fan itself as well as the relas. However I do not know where these sensors are located or which one of them it even has or if both.and my chiltons won't list anything about thec please help!

Do you have a 2000 Civic? If so, a bad pressure switch would not prevent the condenser fan from running. Does the fan run if you jump the fan relay socket in the hood fuse box?

Low and high side lines are very easy to find. Normally, the high (hot) side will be closest to the front bumper.
