I am a new owner of a 1992 subaru legacy wagon (140k) with factory pneumatic suspension, recently the "hi height" switch, has been rapidly flashing after roughly 10 minutes of driving. The suspension appears to be operating correctly, isn't bottoming out, isn't sagging, the compressor sounds like it is operating correctly. My question is why is the "hi height" switch flashing and what are some possible solutions before it goes to the dealership. Thanks -
Hey guys, new member here. I recently aquired a silver 87 GL-10 turbo wagon with air suspension and the 3 speed automatic. I essentially got the car for free so I figured if it ran, I'd spend some time and a little money trying to get it running good so I'll have a winter car. It sat for probably 2 years, at least, up in the woods of the northwest. Encouragingly the car started right up with a jump, and it actually drove over 180 miles down to where I live without any needed repairs. So far, the problems I’ve found with the car are limited to the push-button 4WD not engaging( which may be a bad button is all) and more importantly...the air suspension will not lift the car. When I turn the key to ON, the compressor starts running and continues to do so for about 8-10 minutes then shuts off. After it shuts off, the light begins to blink on the dash indicating that there is an error. I’ve found very little technical information on this system that I can effectively use to properly troubleshoot the problem. The little that I have found has informed me that the behavior I just described usually occurs when a leak is present in the system. Because the ride height does not change after 8-10 minutes of the compressor running, the computer assumes there is a leak so it shuts off and projects an error code to the driver. I also read somewhere( and I could have this wrong, please let me know) that the computer will always try to raise the rear of the car BEFORE the front. So, with this in mind I removed the plastic and carpet from the back of the car and checked the air lines for holes. I found out that mice had literally severed the air line going to the passenger-side rear wheel. I bought a couple air-line bridges(blanking out on what they’re actually called) and patched the line. As of right now that’s the only defect I can find in the air system. After fixing that though, the system still does the same thing. It runs for 10 minutes without any change in elevation, and then shuts off leaving me with nothing but a blinking dash again. What I’m hoping for is for someone who has had experience with these air systems to suggest some things to try. Or that possibly someone who has a technical shop manual for the 80’s GL’s could take a gander at the pages detailing air suspension troubleshooting and post some suggestions...maybe even some scans One observation that I’m not sure is important, is that my dad unhooked the middle hose from the compressor that goes to the tank. We noted that he was able to blow air INTO the compressor...which seems like something irregular. But I’m not sure. Maybe it needs a new diaphram? Help me out. Oh and before everyone starts chiming in saying that I should just tear out the air suspension.. I’m not going to put that much work into this car lol Plus, everything seems to be in good condition, the car has 150,000 miles. Thanks in advance guys.
