Hi Misty,

I got you note and will send the pages today. May I suggest while waiting that you check fuse #6 under the dash on the driver side, and then go to the battery and notice that on the + post cable clamp there are a couple of smaller wires, one that is brown in color. That one carries the power to the control panel for the heater/ac also.

It is connected to a black/pink wire that looks like spaghetti which is actually a wire-type fuse. It in turn is attached to black 4-pin plug on the frame rail nearby.  If you have a voltmeter or neon 12V glow light check for there to be 12V on that wire where it enters the plug. Measure between the pin and the - post of the battery. If you don't show 12v then that item, called a fusible link is blown and will need to be replaced. It may blow if there is a short to the rear window defroster which is also powered by that wire.

So check those two "fuses" and then do the self-test when the pages arrive.

Roland
