I had the same problem turn signals wouldn't work windows wouldn't work blower didn't work 4 wheel drive didn't work. it started when I tried to turn off the 4 wheel drive. I found that the 15 amp fuse inside the cabin for the ignition was blown but when I tried to replace it it kept blowing. I got under the car and cleaned off what I thought was the solenoid that engage the 4 wheel drive because it had oil all over it and then put in a new fuse and now it seems to work fine.
