2006 International 8600 *****************. Customer broughtCustomer brought in truck with AC not working, Check Ac on the dash. Found a high ac pressure shutdown code (can't remember the code). Found condenser, Evaporator, and cabin filter full of debris. I blew compressed air through all until clean, cleared codes, test drove, and sent back. After 5-6 hr driving customer complains ac stopped working, ac check light on. I found high pressure code again. Replaced Condenser after noticing a section that was building condensation (I assumed a blockage) Replaced orifice tube and line it sits in (could not remove the orifice). Replaced the high& low schreader valves (noticed weak springs that allowed the seat to move shaken). Replaced Trinary switch for no particular reason. Removed Evaperator from truck and blew out and inspected for leaks. Flushed lines and evap. Replaced accumulator/drier. Charged with 100psi nitrogen and sprayed down entire system. Psi did not drop over 6 hrs. Charged ac 1.9lbs, test drove, and Returned to customer. 5-6 hrs driving customer complains no ac/ light on. Code SPN: 612- FMI 14 Byte 7:23 Byte 8:1. I thought this was a thermistor code and inspected thermistors. Low side thermistor had bare wires at the plug. Installed a thermistor kit for both thermistors, cleared codes, test drove, and returned to customer. Customer drove 5-6 hrs and ac not working, ac check light on. Code SPN 613 FMI 14 Byte 7:1 8:10. I thought this was HVAC control head fault. I found batteries were not tied down correctly and arcing out to the frame. Built a new battery holdown, cleared codes, test drove 3 hrs, and returned to customer. Customer Drove 5-6 hrs Ac stopped working. I test drive the truck to find ac working. I notice at idle when fan engages at 300psi, it pulls high pressure down quickly. When driving at 1800 rpm fan stays on for minutes at a time. Driving at 1900rpm or below 1750 fan turns off and does not engage. Ac blows 25 below outside temp. I am asking for some insight before i send the truck back and have the ac system stop working again. … read more
