you will find bolts in the defrost air vents and under any speaker covers. also in the glove box. make things easy and remove the windshield first. can be done with the windshield in place but much harder.

Dash board speedometer, rpm gauge and all other instruments turn off. If I beat on the dash sometimes it all turns back on, but mostly not! Also when instrument panel turns off, door locks won't...


Sounds like the instrument cluster main wiring harness pins on the instrument cluster circuit board. How are you with a soldering gun? Just re-flow the solder on the 13 pins of the main wiring connector on the instrument cluster circuit board, and you should be fine. To get there, you need to remove:
- the lower dash panel under the steering wheel (5 screws),
- instrument bezel cover around the steering column (2 screws),
- instrument cluster cover (3 screws to my recollection),
- and then instrument cluster (4 screws)

If the problem returns or persists, then consider re-flowing the solder on the #331 resistor on the body control module circuit board - there is only one of these on the circuit board. To get the bcm out, remove:
- lower dash panel under steering column (5 screws)
- metal kick plate - 10 bolts and 1 screw (although not necessary, you can get more room by removing the lower metal dash bracket as well - 5 bolts)
- three 10mm bolts holding the bcm in place
- 2 wiring connectors on the bottom of the bcm
- 4 wiring connectors on the front of the bcm - You need to back off the connectors with a nut driver - they were either 11mm or 12 mm

Then:
- remove the metal bcm cover - 3 small bolts
- remove the circuit board - 4 screws
- use a magnifying glass to find the #331 resistor
You're probably best off replacing this resistor while you have everything accessible. (this is apparently the standard re-build fix for these bcm's) I didn't have a suitable replacement, so I just re-melted the solder. After re-installing everything, all my previous dash board gremlins disappeared.

Give yourself 2-3 hours (well maybe 4) for all this.

Land Rover Discovery I dashboard replacement.


There is a little more to it than that, but not a tough job if you have patience. You will need to remove both 'doors' on the dash-one glovebox, one fuse access panel. on US models, you will need to remove the pass side airbag as well, then 2 bolts that hold a set of relays under the airbag, then 5 bolts that hold a support bracket (also under the pass side airbag-behind glovebox.

Then under the dash at teh outside near the doors, remove 2 sets of 10mm bolts. after than remove 2 sets of 10mm bolts near where the bottom of the dash touches the tranny tunnel. obviously all the center console needs to be removed, and the center panel of the dash, as there are several sets of screws that hold that to the back of the dash.

be patient, take lots of photos of how it goes together, and where the wiring is(was), and this is pretty easy.

Thanks

Removing front and back speakers in 1991 Grand Am....


There is a lot involved in replacing these speakers. You should also know that the original factory speakers are 10 ohm speakers. This means that if you replace them with new speakers (most of which are 4 ohm) you run the risk of damaging the stereo, the speakers, or both. This can also cause a potential fire hazard in your car. If you want new speakers, you really should look at installing a new stereo as well.

To get to the back speakers, you will need to remove 2 bolts located under the front edge of the rear seat (bottom). After you remove the bottom, you will need to remove the rear seat (back). This involves removing the bolts that hold down the rear seat belts, which is a large sized torx bit (T-45, T-47, or T-50... Don't remember which). After removing these, lift straight up on the seat back to remove. Now remove the deck brake light housing, and the bracket that holds it. Now the deck cover can be removed. Be careful not to bend it too much getting it out from under the side trim on both sides.

For the front speakers, you must disassemble a good portion of the dash. Remove the screw holding the light switch and the wiper switch housings. This screw is underneath each housing. Once removed, there are dash mounting screws behind them. These screws (and many of the other dash screws) are a smaller torx-bit (T-10 or T-15, don't remember which). Sometimes they use a 7mm bolt. There is a cover panel just above the glove box. This panel is held on with 2 screws located in the glove box. After removing this panel, you will find 2 or 3 bolts holding on the dash. Last but not least, you will find 2 bolts inside each of the defroster vent grilles. These grilles just snap out for easier access to the bolts.

Remove Dash On 1988 Camaro IROC


You do not have to remove any part of the dash at all! All you have to do is use a socket wrench from the front of the box with an extension over the top of the box. There is even a dip in the box at this point that may have been designed to make it more accessable. I have a 1988 Camaro and removed this impossible to reach 5th bolt by using a 9/32 socket and an extension or two to get the right lengths and a universal joint for easy manouvering. My son helped by holding the socket on the bolt while I did the unscrewing. It helps to have a good variety of socket wrench extensions and a universal joint and a skinny arm to get behind the box. The fifth bolt is about 3" in from the upper right bolt. Same size bolt as the other 4.
