I have a 86 mustang 5.0 HO car.
I am getting ,right side thermactor system inoperable,I have traced it to the tab /tad...thermactor air bypass ,thermactor air diverter solenoids.
Ford sayes if they click ,there fine when power is applied,I have read other places that they need a resistance test and need to be between 58 and 108 ohms resistance to be good .

Anyone have any exsperiance with this ?

I applied vaccume to where the solenoid is suppose to supply vac and the thermactor system works,its almost positivily the tab/tad solenoids.

Anyone have a good source for these or any advice on this problem or further tests that could be run?
