Question about 1992 Subaru Legacy
Posted by Anonymous on
The most common issue with the older legacy cruise control units was either the clockspring wiring or the main control unit has becomes faulty. The clockspring is behind the steering wheel and the coil wiring inside dries out and breaks. The fix is to replace the clockspring or just the coil wiring inside. The main unit can fail one of two ways either the vacuum hose leaks from age and drying out or the internal seals fail.
There is the possibility its an electrical fault so here is the basic wiring info
the control unit is mounted in the passenger kick panel
below is a link to a pic of the unit

To properly diagnose problem and the seriousness of it, you should either purchase an OBD2 code reader or take it to a mechanic to read the code and diagnose the problem based on the code. I've also heard you can go to an Autozone store and their staff will let you use their code reader for free.
The OBDII port is located just inches below the steering wheel.

Take the car to Autozone or similar business for a free code read with a scanner. Depending on what turns up, they will be happy to sell you any needed parts.

Hi and welcome to FixYa!
It's definitely a cruise control relay failure. If the relay is faulty issues like this occurs. But before replacing the relay I strongly suggest that you remove the positive battery connector. Let it sit for atleast 5mins. then reconnect it again. Go for a few runs and observe if the cruise control is working again. Removing the positive battery connector will reset the system and may get the car back to it's normal operation.
If it still doesn't help then it's definitely the relay.
Hope this helps and thank you for using FixYa! Have a good one!

You need to get it scanned to find out what the issue is.
Tthe cruise control not functioning is a safety feature that saves the engine and transmission from possible damage due to the fault.
