2008 Subaru B3 hatchback, 135k miles, automatic
The AC works on both sides, the heat works great on the driver's side but blows cold on the passenger side. It does not make a difference if it is set to floor, regular, or to blow up on the windshield.
Coolant and Freon are topped up, both mechanical actuator doors (I think that's what they're called, the thing I can see from under the steering wheel or behind my glove box that moves when I change from heat to AC) open and close completely when switching from cold to heat.
I had an issue at one point that when the air conditioning would run I would have a puddle on the floor under the passenger side in the front of the car (where the heating no longer works). My mechanic did something to stop the leak, but he skipped town and is no longer answering my phone calls, and I have no idea what he did. I just know that when I got the car back from him the heat would no longer work on the passenger side.
Please help! My kids are freezing, and I can't afford going to another mechanic.
It could be a blocked/leaking heater core but I don't think so. Check ALL of the blend door actuators, there's multiple of them.
Thank you so much for your answer.
The only blender doors that I could find are the one by the glove box and the one by the driver.
Is there a manual or a video that could explain to me where the rest of them would be located? (I'm new at this whole car repair thing)
Flush the heater core. It most likely solves the issues.
