gl10

Howdy fellow Subaru folks, I just bought my first "new gen" Subaru, a '92 Legacy sedan 5 speed. Definately an upgrade from the '86 GL10 in terms of handling, power not so much. Anyway I have this problem where when I push a heater control button while driving steadily down the road, I feel a sudden jerk, like the ignition is cutting out momentarily. It doesn't seem to matter what button I push or how many times. Has anyone else had this problem? The heater seems to work OK.

I didn't want to make new holes either and my aftermarket sender had standard threads, so I broke the plastic off of the old sender and tapped the brass with a pipe tap. Worked great for my VDO sender. I had to saw a bit off the end of the old sender to get the new sender deep enough.

Well, I looked around a bit more and from what I can tell, the button actually controls a vacuum solenoid attached to a linkage that extends to the transfer case. I guess I just need to jam that lever in place somehow. This may explain why there are 3 wires to the button, one to open the solenoid and one to close it.

I'm actually working on the same thing now, for an 86 gl-10. I plan to leave it in 4wd all the time for a rwd conversion. My Heinous Repair Manual says nothing about it! What would be the best way to engage the rear end permanently?
