SOURCE: removing dash board from 1969 chevelle

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

- 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.

How do you replace the blower motor on a 1997 cavalier?

I believe on that you have to actually remove the dash to gain access. Remove the speaker grill on top and there are a few torx screws under that. Remove the side access panels, when you open the car doors you will a panel on each side, they are just held in there by pressure and small nubs on the panels, you will find more torx screws. In the glove box on the top towards the front you will find a few more torx screws, also in that area there are two 10 mm bolts that are somewhat hidden but accessible. After all the bolts and screws are removed you can pull the dash cover off, becareful because on the passenger side, the airbag has a paper type cover on it, you don't want to damage that. From there you should be able to gain access to the heater blower on the passenger side of the vehicle. Good luck.

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.

Its not hard to change. The hardest part is getting to it. Start by removing the glove box. It should be behind that.

Where is speaker harness

Under your dash on the drivers side there is a big connector that I think has a little bolt to hold it together. Just underneath that, there's a smaller connector with like 26 wires in it. That's the only intermediate connector that goes to both front speakers, but it's got so much goin through it that if it were disconnected you'd have a bunch of stuff not working.
