No such item -- "relay sensor". However, relays themselves are located:
1. in the Relay Center -- behind the glove box (open glove box, pull rear wall tab toward you while continue opening: dump glove box contents on floor). Behind and to the right, at kick panel.
2. in the engine compartment, at the filewall, under a 2-nut cardboard cover.
3. in the engine compartment, at the load leveling compressor pump.
Most "sensors" are located in the engine compartment. Plz re-submit question and be a little more specific.
I will jump in and say that there are many locations for relays such as: 1) the relay cneter array located in eng. comp't on pass side just below Maxi-fuse array and has cover over top of both. Remove two plastic snaps by twisting. Push aside cover to locate relays and fuses above. 2) On passenger side near floor. Remove bottom cover near floor and drop this down. You will see both fuses and relays looking up and right. Diagram on inside of cover mentioned above. Mike from MN

The 1991 Buick IAT sensor can be found in the air intake hose. The IAT sensor will be between the air box and the top of the engine.
AC relay is on the far left passenger side under the hood on a 93 Buick Le Sabre also. About $9.00 from Nappa.
