In Reply To	Evaporator Freeze control 1994-96 cars. posted by JMartz on January 02, 2014 at 09:21 AM
Message	:I have posted on this topic in the the past. This is a rarely mentioned area on this forum, understandable, as fewer of the cars are of the years 1994, 1995 and 1996. Freon 134a cars (introduced in 1994) use a pesky little sensor on the dicharge side of the evaporator to control refrigerant expansion and freeze up. This device sends a voltage signal to the ECU, which in turn, shuts off power to the compressor clutch magnet. The sensor actually sinks pin 46 of the ECU to ground rather sending it voltage I haven't tried splitting the box in situ yet, because I'm usually gutting the TSV anyway on earlier cars. FWIW, the TCA from a Nissan frontier only costs about $30, and can be easily retrofitted. I plan on a writeup at some point in the future.
