Default Legacy no heat issues

New to these forums and new to Subarus. I recently got a new to me 93 BJ Legacy 2.2L. There is no heat from the vents. It does feel like there is some air movement from the vents, but I never hear a motor kick on, and dont really know if I should be hearing one. I've been doing some research and it looks like no heat is a symptom of a "phantom overheating" issue that was present in these cars. I'm trying pin down what is causing this before I just start throwing parts at it. Any help you guys can give me will be much appreciated.

Thanks,
-Jake

Check your heater core. If you have air flow but no heat that's where I'd start. Fairly cheap and easy to replace if necessary. Also check the lines leading to and from.

Alright I'll check that. Is there different models for LHD cars and RHD cars because I have seen some people listing their heater cores as LHD Heater Cores and my car is RHD.

Wait, so it doesn't blow air period? Or it blows, just not hot air?

On full blast, it'll blow a bit of cool air on cold (feels more like it should on setting 2) , and practically nothing on hot. Like if I held a pinwheel in front of it, it would struggle to spin it.

Maybe a worn blower motor or bad climate control unit?

Hmm I'll have to check those. Anybody know where I could find these parts that would work on my car?

If someone else would confirm this, I'm thinking this may be it.

If the fan is not blowing distinct speeds for each setting, It's likely a bad connection in the resistor in the blower housing (assuming Subaru has the same thing in that year vs. later years).
You can fix it yourself, or buy the part.
I did the fix on my wifes 1999 Impreza.

If the fan seems "OK" (not likely...but...), then a reverse flush on the heater-core may help. You can do it in the car, outside the car is "easier" for the flush, but more time consuming.
Basically, pull both heater-core hoses, run a hose (full pressure) through the "out" of the core and see if crap comes out.

Also make sure the system is properly "burped" to take an "air bubble" out of the issue.
