I'm looking to buy a thermostat switch/controller for my 96 XJ. It's a copper probe that goes in between the evaporator fins and has a couple of wires that plug into the dash harness. The Jeep dealer is way backordered and doesn't have a clue when they might be available again. Junkyard ones are fused to the evaporator due to dissimilar metals and cannot be removed without damaging them. Does anyone know of an aftermarket source for these??
