Customer: replied 11 months ago.
HI we have a 2005 freightliner M2 in the shop and we have been fighting the ac system for the past two days now. This truck has an evaporator probe in the evaporator compartment and every time we take that probe out, the A/C works fine, but it doesnt no when to shut off the compressor. when we put the probeback in, the compressor kicks off almost instantly. Do you have any ideas?

Thank you for that

Compressor will not shut off with the

probe out, have you replaced the probe
