2002 Outback, heater not working
Posted 04 December 2012 - 09:24 PM
Unfortunately, I've never been in the car. So I don't know what the engine, trim, etc is. Just that it's a 2002 Outback.
I'm trying to research a bit before I get the car, but I'm not finding much help in the PDF service manual I sourced on the web.
I assume the heater blend flap is electronically controlled. Can you point me to the location of the servo? I'd like to at least be able to rig it to medium heat for her.
Any suggestions? Thanks!

I can snap pics tomorrow if you need 'em.

Is the temp gauge normal at the mid point range? If not, have you replaced the thermostat with a factory thermostat?

What does the temo gauge read?
When she turns on the blower does air move?
Is the heater core bypassed?

As I said, I have not had hands on the car yet. Was hoping to get some ideas. I've been googling and I haven't gotten the impression that this an exceptionally common problem.
I'm a reasonably competent hobby mechanic, I'm just completely unfamiliar with the car. I'd appreciate pics it you've got them, get me some idea what I'm looking for/at.
So if I look under the dash I should be able to verify the linkage is connected and operating the flap without any dash disassembly. And the heater lines are accessible enough to grab hold of and feel temp. That's a start.
Are heater core failures common? I'd assume that's the only reason it would be bypassed. If the thermostat was stuck open, I'd still think she'd get some heat, but I'll check. I have an OBD2 scan tool that reads realtime data, should be able to watch the actual temp with that.

Cores really rarely leak, but it does happen. Sometimes a miss guided fool will blame a heater core for causing a HG failure (dont ask) and choose to bypass the heater core.
This may be as simple as the control cable not working.
Another possability is a bad radiator cap.
Has she complained about mpg being poor?

I'm hoping for just a missing clip of course. I'm glad the linkage is exposed enough so that I can at least rule that out quickly.
I just took the dash out of my Range Rover to troubleshoot it's vents. I thought I'd have to replace the expensive blend servos, but turns out it was just a gear not engaging the defroster flap shaft correctly. A $0 fix for me, but pulling the dash fascia is still a hassle.

There is one other fault on her car, her running lights won't turn off! She has to pull the fuse to keep the battery from going dead. I'd figure that's the switch on the control stalk not going all the way to the off position. Might have to start up a new post to see if that can be disassembled at all.

I bet that it has been accidently switched on.
Just switch it off, and put some tape over the switch.
