1997 Impreza Outback Sport Issue: No power to Blower motor Things I have replaced in system already: Blower motor, Blower motor Resistor, *Climate control module (to see if the fan switch (actuator) was broken)), Blower Motor Plug (Then I realized could have just checked it first with a multimeter), Blower motor fuses. I bench tested the blower motor relay (which was very difficult to get to), and it clicks, shows continuity and voltage when powered, have a replacement on the way just in case. I have checked every fuse, every relay, the next step I suppose would be to make sure that the system is grounded properly and that no wires are damaged, not sure how to do that. What I know: No power is reaching the BM plug, BM relay clicks when I switch fan from "OFF" to "1" which also means power must be reaching the CCM, Bench tested BM, BM relay, Fuses-all either tested functional or were replaced anyway (BM relay will be replaced at the end of this week but it bench tested functional so I do not think that is the problem). My Assets: A small tool box, a multimeter, 30Amp wire spools, butt connectors and heat shrink, YouTube My questions are: How do I go about finding the wiring issue i.e. ground is poorly connected, or wire is damaged, or should I simply snip the lines from the BM relay to the BM and replace them, and how would I do that, (obviously I need replacement wire and to make sure the old wires are sealed off properly, but how do I make sure that I don't mess the system up, and that I can trust the wiring diagram I found to be enough information for me to connect a power and ground wire to the BM plug so it'll get power. *I replaced this with a used part, so maybe I got unlucky and got a bad fan actuator twice? should I buy a new actuator for the CCM? Is there a way to test if the actuator I have is good? NOTE: The blower motor was making loud noises (like a bad bearing), but had power from 1-4 one day, the next day I only had power to 4 (bad resistor) and then one day I left my car to warm up with the fan on full blast and when I came back it had ceased to work entirely. I have scoured the forums for BM issues which has been helpful, but none have led me to a solution in my case. Attached is the wiring diagram that I am going off of, advice about what my next steps should be are greatly appreciated. Blower motor wiring diagram.svg -
I've been tracing wires trying to figure out why the blower doesn't work, I checked the fuses and they were all good and then I took the blower motor out and hooked it up to the battery and it ran. There was a singe red wire with coupling and then a 3 wire coupling (similar to the 4 prong on a small trailer hook up) from that I trace the 3 green/red/black wires to coupling for the selector panel fan switch which had yellow wires coming out of it, it had one black wire clipped close to the panel side of the coupling, and one extra yellow wire with a coupling that had gone to the ac before being disconnected. the only question I have is I found the blue wire coming directly from the panel switch that went through the firewall into the engine compartment to some silver little small box with wires going into it. I didn't know if maybe you might have some input. Little silver box I'm talking about with the wires is to the left of the spare tire as you're facing the vehicle from the front with the hood up.

For diagnosis: No fan speeds for Blower motor at all~ so from what I hear probably not the resistor. Also, the Blower motor stopped working all at once, no intermittent failure~ if it were the switch wouldn't it be likely to fail some and work other times? I'm thinking it's the Blower Motor Relay~ Haven't taken a meter to anything yet~(need to purchase one). 2 quick questions before I proceed: In the photo of the relay comparison~ Based on location (just above the fuse box) and appearance, I think I've found the Blower motor relay for my Brat. Problem is, the other Relay in the photo is in a Loyale. Can anyone confirm I've got the right Relay Location for an 86 Brat? Manual I have doesn't show it at all~ 2nd question: From the second graphic from another Subaru Repair manual (again a Loyale) it shows another relay under the hood (?) Is this a possible cause as well, and can anyone confirm which exact Relay it is? Not having direction that is "Brat Specific" has been frustrating. I've got the dash all apart already & am not putting it back together until I get the fan running again Please let me know~am I getting close? Thanks in advance~ BRATMOBILE

Okay I know why it's not turning off, sixstar automotive did this to my moms subaru when her hvac controls went out. I have since fixed them using legacy777's write up but whatever six star did is still operating the fan all the time. I looked up where the heater fan relay is but, I got conflicting story's. I believe the relay is behind the left hand kick panel behind the fuse box, is that right? Also does anyone know what they might have done to make it work like this? The way it's hooked up the fan will run even if the hvac controls are unplugged. I believe they were messing around with the relay, but I can't find any wiring diagrams on the climate controlls to even get an idea of what they did. Any help would be appreciated.
