I have a 1991 loyale that I love and often abuse on serious offroad expiditions. This year after working in the desert for 2 months on sandy roads, one day the 4wd would not come on. I highley doubt it is anything mechanical because it worked great up until the day it stopped activating. Does anyone know of a master fuse or have any suggestions on how to check the electrical in the activation button.

I presume you have the single-range, pushbutton 4WD?

 

there is an excellent guide to troubleshoot it here: http://www.ultimatesubaru.org/forum/article.php?a=47

 

I got the link from the USRM link in the header above.

Thanks so much for leading me to that website. Grand total for 4wd repair = $0.38. Apparentley a mouse decided to use a segment of the vacuum tubing that actuates the 4wd for a nest under my hood.
