Air control unit broken and can't find replacement
Posted: Thu Dec 14, 2017 5:58 pm
I am new to the forums and the Subaru world, but have been searching and reading the forums since I bought my 1990 legacy a few months ago. It is a project car with some minor issues that have been getting fixed, but my biggest issue that is stumping me is I cannot get ac/heat to work at all.
I have pulled parts from the systems to test if they are working or not. I pulled the blower motor and it is fine, tested the blower motor resistor and it is fine, pulled the blower motor relay and it is fine, yet I have nothing at all coming from the system. I have been testing everything with a multimeter to check for continuity and power to these parts.
The control unit has been pulled as well and it receives power signal from a few of the wires, but it has no response when pushing buttons or ever having the lights coming on. I am thinking if that is broken and making the system not blow air in any way, but am unsure of how to test the continuity on it.
I have looked online as well and cannot find any air control units in order to even replace it for my car, all I can find is the outback ones from a newer body style. Has anyone seen these for sale anywhere used or know something that I can do to properly test mine?
