Pearl, 90 Legacy LS

218K+ miles

My tranny works decent for it's age, AWD works when it wants to.

But it will let me know by the lack of lights (Sun roof open and shift indicator lights) or the presence of them.

Lights on, AWD is good to go. Lights off, I'm stuck in FWD like the FWD fuse is in.

I have found that a sharp rap to the dash will toggle it. So I have a loose connector I presume but not to interested in taking dash apart to fix at this time. Even though there are two other gremlins in there!! (Tack and heater)

 

So, my question is if I install a manual switch to ingage/disingage the AWD will it bypass my gremlin?

yes, assuming nothing really funky is going on (doubt it). all you need to do is control the duty C circuit (one wire!).

Don't forget to place a 10 Amp fuse in that line.
