A/C Switch 200 1987

A capillary tube is used to connect the fluid from a remote sensing point to a switch element. If the tube is broken, there can't be any pressure on the switch, so it can't turn on. It would be a plunger or pin in the middle of the switch body. There's no magic here- it's just a sealed copper or brass bulb with a fluid like ammonia in it- something that expands quite a lot with heat. These style switches are used in every home air conditioner, refrigerator, dehumidifier.... they all work the same. You probably can't get it to work without a new capillary assembly. You can probably pull the old bulb out of the goop on the evaporator and get a new one in there, if you can stand working way under the dash for a little while.
Good luck!
