I have a 1986.5 TOYOTA SUPRA . I'm having a problem with my heater it does not work. I noticed that it was broken the winter after the car got a new engine put in. The car went to 3 shops including the one that put the engine in and none of them could fix it. The heater control valve is working. I thought it may be the motor on a air door. but I was looking around and noticed that both connectors on a vaccum swich (located near the thermostat on the radiator) were broken off and there were no vaccum hoses going to it. I found a pic of the swich online. Could anyone tell me where the 2 vaccum hoses go to?
Its the one on the top left
