Hey guys I was just wondering if you could give me any tips on how to fix the power door locks and windows on my 1990 toyota pickup 3.0. I replaced the switches on the drivers side thinking that was the problem but that didn't fix anything. I was thinking it may be the a fuse but I couldn't find any fuse with a name related to the power doors? Thanks for reading.

 

It might help to give some details about just what your problem is

My crystal ball is out getting over hauled at the moment

 

Haha sorry about not specifying. But my door lock and my windows will not roll down. The power mirror switch still works but nothing else does.

 

The answers to all questions are found in The Good Book.

You have a 30amp fuse "Power" that controls the motors. Gauge powers the door lock relay, and dome also has something to do with its function.

Replacing a (expensive?) switch on gosh-and-by-golly hope is nearly as useless asking generally for "tips" on how to fix it. This is an electrical problem, there is one tool you cannot do without: a multimeter. Don't have one? No excuse for that! http://www.harborfreight.com/7-funct...ter-69096.html

Since you've already figured out how to remove the master switch, I'd start by checking for 12v to ground on pin 9, and then 12v between 4 and 3 as you actuate the driver's side window switch.

Good luck!
