evap temp switch
I have been reading a few posts today about modifying the evap temp switch to keep the compressor from cutting off to early and it got me thinking. I pulled out the switch and left it hanging and went for a cruise and I was able to achieve 38 degrees at the center vents wheras before i could get at best maybe 46 degrees on a long highway run. If I solder in a resistor, to keep the compressor from cutting out at around 45-50 degrees, would it be safe to let it go down to say 40 degrees inside the evaporator box or could I let it get colder in there? Also, does this kind of mod really work on a 95 degree sunny humid texas day? So far I have only tried it at night when the ambient was around 83 degrees.

Is there a way to test if the sensor is in range, before I replace it?

Just as I suspected. It makes no difference at stop and go driving, but does wonders on highway temps. Its gone down to 36 degrees at the vents. BBBRRRRR
