'91 4x4 electricals

[mpierich]

Hi,

New member here. Mike's the name...please allow this to serve as an intro. I have a '91 that has served me well but always had probs with the electric shift and now it's completelly dead.

I read Brain's excellent article on rebuilding the servo motor (thank you sir) and I intend to take it off and service the contacts, etc. at least. But I can't seem to find a search function for the board; I'm looking to check the computer module and see if there is juice going to the motor.

Can anyone direct me to a thread or two that will take me from the module the whole way to the motor so I know everything else is OK before I tear into the servo itself?

Much appreciated...we're having a thaw now but it's just a matter of time before it snows, and where I live I can't be without the 4x4...feeling a little desperate now since I can't afford a mechanic. Any help?

Thanks.

volts meter

if you get under youre X pull the conecter of the shift motor
hook a volt meter to the yellow and orange wire coming from the inside of the car ( not the ones on the shift motor )
get in turn key push 4x4 and look at the meter to see if there is a voltage showing up
if not than you found the problem.

Carefull this is all theorie i havent tryed it myself since i busted my shift motor before i could try anything else.

Thanks again...sounds like you need to get a smaller hammer (just kidding!).
Well at least if you replace the motor you shouldn't need to fool with it again for a long time!

Heck, I might give that a try tomorrow. Rebuilt mine twice and still nothing. Might as well have a two wheel drive
