Bought an 88 lancer shelby. It has an ASC aftermarket sunroof in it that has never worked since i bought the car. Im told that they used these sunroofs for a year or two but cant find a ton of information on them. I have tested as much as i can without a diagram or more knowledge of how the sensor and the circuit board is supposed to work. Rhe switch works. The motor also works when applying power to it. I have power coming out of the circuit board and to the switch then back to the circuit board but it doesnt send power to the motor thru the circuit board. Would anyone be able to shed light on this thing? Anyone have parts or know how to test these properly?
