I have a 1999 GMC Jimmy SLT that has an overhead digital temp and compass display, one day it just doesn't display anymore. I can't figure out if a fuse blew or a light is just out. I can't figure out how to get into it. I did check all the fuses on the drivers side door panel and they all show good.

There should be a fuse panel located in the engine compartment, and possibly one on the right side of passengers side dashboard.

If the lights in the console are functional then it is most likely not fuse related. These consoles are notorious for going bad. You can get a new one at the dealership for $250 (!!!), grab one from a wrecker, or I offer a repair solution with a lifetime guarantee. Check out www.autoclockrepair.com I have removal instructions and info there. Please let me know if I can be of further help, thanks!

SOURCE: my overhead compass/temp quit working

It's a known problem with these units. There are two resistors on the board that come unsoldered. If you have access to a soldering iron, you can easily fix it yourself or find a buddy with one. One screw in the eyeglass compartment and then you pull the plastic housing down from the windshield side. It takes a concerning amount of force but as long as you pull evenly from both sides it will pop loose. The clips that hold it in may release and fall into the console so keep your eyes open! Then slide it towards the windshield and pull it down. Unplug both connectors and take the unit down. On the underside, there are three #10 torx screws to remove and the module is free. Turn it over, carefully remove the plastic lens and look at the two black rectangles in the lower right corner of the board. Sometimes the fault is obvious and sometimes it is not. Those are 51 ohm surface mount resistors. You just need to resolder them to the board and that should fix your problem and save you $900!

SOURCE: 1996 jeep grand cherokee - overhead computer read out

All that info is actually relayed from the PCU which is expensive to replace.
Have a certified dealer look at it before you go replacing parts.

SOURCE: 1996 jimmy gmc fuse box

Look on the driver's side fender well under the hood. Should be a long black rectangular box there. That is the power center or fuse block. The relays and fuses are inside. The top is not hard to remove. Hope this helped and best wishes.

Check the wiring plug that goes into the back of the mirror. They come unplugged sometimes.

SOURCE: the digital compass on my 2006 tacoma is out, how

Are your cruise control, dome, and tail lights also out? If so then it is a fuse. If not then the control unit has gone bad internally. You may be able to get it fixed under your warranty.
If it is not covered by your warranty, check out
www.autoclockrepair.com. We offer a very reasonable repair solution.
