Default A/C Compressor Clutch Low-Pressure Sensing Switch

Does anyone know if a 2002 TL Type-S has a Low-Pressure Sensing Switch that may be bypassed for A/C system troubleshooting?

My cars compressor clutch nor condensor cooling fan will engage.

If anyone has any suggestions to rule out any electrical switch issues, I would appreciate it.

Thanks,

After removing the leads to the clutch, put 12v directly on the clutch to see if it engages. The clutch should draw about 3-5 amps. If it draws more, it's on its way out. (I'm assuming you have an ammeter.) If nothing happens, it already went out.
