Check the wiring inside the rubber flex boots between the van and doors. I had wires corrode and brake inside them.

My power window switch stopped working, gas lock, trunk & radio, changed the master switch to no avail, we had bought new window switches awhile back so we know it's not those I need help

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 .

Hand held diagnostic tool

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

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.

99 concorde power windows, signal lights and heat does not work

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!!!" Site is: I hope this helps you out!

99 yukon denali drivers side turn signal in rear tail light not working, i replaced bulb and still nothing, I looked at the connections and wires and found nothing, front turn signal blinks fast, passenger...

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.

Does the 2003 trailblazer have a on board diagnostic system? if so how do i activate it

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 and let me know if you have questions.

I need to set the distributor timing

These vehicles have to have the timing set while hooked up to a diagnostic computer as they are self setting once they have been zeroed with the diag, computer. if you try to set it on your own you will just be fighting the vehicles control module (computer)

Cannot find where to plug 16 pin diagnostic controller

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!
