Can only be in one of two places-- either evaporator inlet (small 3/8" line) or at condenser outlet... look for the dimples (crimps) in the line that holds the OT in place.....

The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......

It is in the line from the evaporator to condenser. You can remove the line on either end to remove the OT. Like GM Tech said just look for the small dimples that hold it in place.
