heater servo motors
« on: November 23, 2013, 02:27:55 PM »
Hey all!

My '89 DL Wagon has no heat. The blower runs, but not hot air comes out. I've drained, flushed and replaced the radiator, thermostat, hoses and belts.

I haven't tested them yet, but I'm suspecting the vacuum servo motors or another control issue. I'm looking for a source to buy heater parts, and other interior parts if you know of any.

Thanks!

John

if your car is anything like my last two subarus, you should be able to take you glovebox out of the way and have enough access to test everything.

This might be a suggestion that you don't find helpful, but RockAuto may be a location for parts.

thanks onemanzu!

i've got most of my parts so far from rock auto, but they don't list the servo motors.

i decided to remove the whole dash so i could fully address any remaining mouse issues.

this is my heater motor: :o

WOW. that's crazy. Does the heater work now?
you really should. it sounds better than two V8s having sex with a blowoff valve while a v12 tapes the whole thing.

thanks all!

round two in the assault on the mouse fortress:







took quite a bit of mouse material out of the heating system. if i'm interpreting the system correctly, fresh air is drawn in and blown past the a/c coil, before it passes over the heater core. with so much material blocking the fan and a/c coil, i doubt very much air was getting to the heater core. i'm going to drain the coolant and finish removing the core, to make sure i get all the mouse houses out of the system. i guess i'll try to vacuum out the vent area that's built into the body.

i used a vacuum gauge to test the servo motors and they all seem to be functional and hold vacuum.

questions:

are these vacuum motors a notorious wear item? i don't want to tear this dash out more than once in a lifetime, so i want to replace anything that might be apt to fail in the future. on the other hand, if i can save a buck, that's desirable since i'm out of work right now.

is the worn out weather stripping between the components anything special, or would something from a hardware store suffice?

thanks!
