SOURCE: speedometer gauge/climate control lights dont work

Look for a dimmer wire,, sounds like your radio dont have the option for the car dimmer switch,,

the power for these lights run through the dimmer wire for the radio. ether its not hooked up or the radio dont have the option for it.

there is a way to bypass the radio dimmer option,, BUT you have to know what your doing or you could fry something.

look for Car Radio Illumination/dimmer Wire: should be Green.

The odometer, gas gauge, basically none of the instrument panel registers anything. What is it?

It could be a loose plug on the instrument pannel or a blown fuse. Sometimes if you hit your dash right above the guages they will come on for a seccond. That will tell you its a loose plug on the guage cluster. First I would check the fuses though. Hope that helps. Write back if neither of those work.

The car runs but the instrument gauges do not work; therefore I can not tell how much gas, what speed running, oil pressure etc. The panel was changed then the Body Mount Module was replaced. the gauges...

Start by checking the fuse for the dashboard displays. Even if it looks good, replace the fuse with another. Sometimes fuses can actually fail without looking blown. If the fuse is good, then the instrucment cluster ground wire may have come off. If everything is plugged with one master DIN plug, then that may be loose. If none of these, then the circuit board in the instrument panel may be defective.

Fuses got wet

Blow fuse box dry with a hair dryer. Look under dashboard, left bottom. And under hood, just inside right front fender, between battery and fender, is the power distribution center.

How could you have possibly gotten the fuses wet? And the only way it would matter is if it were salt (conductive) water.

A little water in there isn't going to matter, not for long.
