Ambient Temperature Sensor - 1988 Sport 5.0l w/ATC March 12, 2019, 02:36:32 PM I need help sourcing a part. I am looking for an Ambient Temperature Sensor for a 1988 Thunderbird Sport V8 with ATC. I have the A/C unit out and replacing the heater core, evaporator and misc parts. I am also doing the A/C conversion (LMR Kit) from LMR. The sensor is located in the heater core blower box and looks in rough shape. I would like to replace it but I can't find a replacement. Anyone know where I might be able to find one or have one for sale.
