Silohuette 99 driver windows dont work,no signal was available from the On Board Diagnostic computer system the someone know what should i do

Before replacing the master switch , did you check for B+ voltage (power) An ground's at the switch ? There are a couple of fuse's a circuit breaker , a relay (power window relay ) An electronic module ( smart entrance control unit ) in the control of all these thing's you have listed as not working . These are very complex electronic systems . Replacing parts isn't the way to fix them when they fail to work , hooking up a diagnostic tool is the proper way ! Checking for DTC'S - diagnostic trouble code's , check data parameters ! Seeing if the control unit is receiving a voltage signal from the switch so it knows when to energize the relay to open the window ,open trunk or the fuel door ! Your best bet would be to take to a qualified repair shop that knows how to diagnose this .

some troubleshooting problems and diagnostic items built into it, which are only accessible with the dealership
scanning tools.

still
OBD 2 systems on GM vehicles use class 2 data. The signal uses both
Frequency and Amplitude to encode the data. This makes them *very*
sensitive to ANY add on electronic dodad.

In the service manual you will find a section stating that ANY add on
electronic component *may* interfere with ECM communication and cause
driveability concerns or SES lites.

If someone does insist on wiring any dodads into the system, it is
recommended that all connections into the electrical system are made
exclusively at the battery. Most add on company techs will not take
the effort to do this Most don't even know about the above.

I went to the Concorde forum and saw what other owners said. Captain mody said, "There is a black case in the middle of the upper part that contain fuse #5 red 10amp you need to replace this fuse by another on and after that every thing will work again" Another guy named Chris said: "Open your driver's door and open the fuse box on the left, there's a handle near the door hinge. This is most likely a blown fuse - check the fuse box lid for the diagram. Find out which one is blown and swap it out. Not a $400!!!"

The circuit board needs to be replaced. Which is the board that the bulbs sit in. If you remove the turn signal bulb. You will notice the bulb socket will be slightly burnt inside. I had the same problem with my 99 Denali and replaced the circuit board for $35.00. Now everything is fine.

yes, it's always active. A light will come on when it detects a fault. You can also use a good scanner to interrogate the system, actuate valves, etc.

Please see my tip at http://www.fixya.com/cars/r5932051-check_engine_light_check and let me know if you have questions.

Your window switch would be the next thing to check and replace. Both the lock switch AND the up and down switch need to be checked.

there's a blend door actuator behind the dash. they are going bad all the times. however, check your coolant level first.

blinker switch can go bad everything runs through the switch

graham, the only 99 civic engine available in the US is the 1.6 L, so this might not help u, but the 1,6 is the traditional location : driver side, under dash, driver side of steering column, behind lower dash panel. To make things interesting, isn't your steering on the right ? (ours is left). Guess u have to check both sides? Let me know if this is any help, if not , I'll try again!

I have a 99 silohuette and the fuses are in the passenger side open the door and you will see it in the side of the dash i hope this help you
